The difference between an engine and a motor and an electric motor

Engine: A power output device that converts other forms of energy into mechanical energy. Motor:

The English transliteration of electric motor, that is, the motor and the electric motor are one kind of object. Electric motors are referred to as motors and can be divided into electric motors and generators. The electric motor is converted from electrical energy to mechanical energy, and the generator is converted from mechanical energy to electrical energy.

It can be seen that the difference between the engine and the electric motor (motor) is that the engine can only convert other forms of energy into mechanical energy in one direction, but not the reverse direction; The motor can not only make the two-way circulation between electrical energy and mechanical energy, but also the conversion efficiency is very high, which is also a major reason why modern industrial motors are widely used.

An engine --- a mechanical device that converts other forms of energy into mechanical energy (currently generally an internal combustion engine, previously such as a steam engine, etc.).

Motors --- power conversion devices (electric motors, hydraulic motors, etc.) that can convert other forms of energy into rotating mechanical energy

An internal combustion engine --- a mechanical device (gasoline engine, diesel engine, gas engine, biogas engine, etc.) that converts the thermal energy of combustibles into mechanical energy by burning combustibles in the combustion chamber

Note the comparison of the extension and inclusion of the concept.

Engine: includes all, internal combustion engines, motors, steam engines, steam turbines.

The structure includes: intake and exhaust, parts for fuel to release energy, and a device for converting energy into power.

The motor is the electric motor: the structure is nothing more than the solenoid coil, the brushes, etc

Is there a comparison? The engine and the motor are two different concepts, and the motor and the electric motor are the same thing, how to compare?

The engine converts chemical energy into kinetic energy, and the electric motor (motor) converts electrical energy into kinetic energy.

I don't know what the difference is you're asking.

No. The principle of the engine (internal combustion engine) is that the fuel deflagration drives the piston to reciprocate; The principle of the motor is the phenomenon of electromagnetic induction.

The engine is also called the engine and the motor is actually the same.

No, although they are all power, but the principle is different Motor: The transliteration of motor is motor, electric motor, and the engine is not the same thing. Electric motors are generally used in stationary equipment, such as water pumps.

However, today's electric vehicles are also driven by electric motors (direct current electric motors). An engine, also known as an engine, is a machine that can convert one form of energy into another, more useful energy, usually by converting chemical energy into mechanical energy.

The term electric motor, which converts electrical energy into machine energy, is sometimes applied to both the power generating device and the entire machine including the power unit. For example, car engines, motorcycles, aero engines.

There is no difference between a motor and a motor, and a motor is a transliteration of the motor of the motor.

A motor refers to an electric motor, which in turn includes an electric motor and a generator. Motor is the transliteration of English motor, that is, electric motor, engine. The working principle is to drive the starter rotor to rotate through electromagnetic induction, and the pinion on the rotor drives the engine flywheel to rotate.

Motor refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction, or converts one form of electrical energy into another form of electrical energy.

Precautions for motor use

Do not plug the motor wires and motor terminals directly into household outlets to avoid electric shock. Do not touch the energized part of the energized terminal during the energizing process to avoid electric shock. Do not touch the rotating part with your hands or fingers during the power supply to avoid injury.

Be careful not to hold the shaft in place (lock) while it is always energized.

Depending on the size of the motor, even a short period of fixation may lead to a risk of burning. Please be careful if the motor is burned due to the operation of the motor (installation status, load, ambient temperature) and the heat of the motor increases.

Many people know about engines and electric motors, so do you know what the difference is between them? 1. Similarities between the two

1. The structure is the same. They are all composed of coils, magnets, commutators, and brushes.

2. The interface mode of components is the same. Each component is connected in series to form a power supply circuit.

3. All are harmed by the direction of the magnetic field, and the direction of the current caused by the generator is related to the direction of the magnetic field; The bearing force of the coil in the motor is related to the direction of the magnetic field.

2. The difference between the two

1. The principle is different. The generator is made according to the magnetic effect of the current; The motor is made according to the principle of fitness movement of an energized conductor in an electromagnetic field.

2. The way of distinguishing is different. The right-hand rule is applied to the direction of the current in the generator; The left-hand rule is applied to the direction of the fitness movement of the electrical conductor in the motor.

3. The transformation of purpose and energy in work is different. Generators need external work to convert mechanical energy into electrical energy; The motor is open to the outside world and works to convert electrical energy into mechanical energy.

Generators

Generator refers to the industrial equipment that converts other ways of electrical energy into electrical energy, which is driven by hydro-generator sets, steam turbine generators, diesel engines or other transmission equipment, and converts the energy caused by the ignition or fusion reaction of flowing water, cyclones, natural materials into mechanical energy and sends it to the generator, and then converts it into electrical energy by the generator.

Generators have common major uses in industrial and agricultural production and manufacturing, national defense and security, high-tech and daily life. There are many ways to use generators, but they all work according to the fundamental laws of the magnetic effect of electric currents and the fundamental laws of magnetic field forces. Thus, the general criteria for its structure are:

Equivalence circuits and power supply circuits are composed of magnetic effects that carry out electric currents with moderate magnetism and conductivity raw materials, so as to create electromagnetic induction output power and achieve the purpose of heat transfer.

Electric motors

An electric motor is a kind of machinery and equipment that converts electrical energy into mechanical energy. It uses a plug-in coil (that is, the motor stator winding) to cause electromagnetic oscillation, and acts on the motor rotor (such as a squirrel cage closed aluminum frame) to generate a photoelectric driving force and rotational torque. The vast majority of motors in the power supply system are AC motors, which can be synchronous motors or three-phase asynchronous motors (the electromagnetic field speed ratio of the motor rotor and the rotation speed ratio of the motor rotor do not maintain the same speed).

The key of the motor is composed of the motor stator and the motor rotor, and the orientation of the plug-in transmission line in the electromagnetic field is related to the direction of the current and the direction of the magnetic inductance line (magnetic field direction). The working principle of the motor is that the electromagnetic field acts on the force on the amount of current, which makes the motor rotate.

In essence, there is also a big difference, the engine is run by kinetic energy, and it needs to add oil, but the engine is operated by electric energy, so it works by the battery endurance, and it cannot be used without electricity.

The essential difference is that a motor converts electrical energy into mechanical energy, and a generator converts mechanical energy into electrical energy. The concepts of the two are also different, the applicable occasions are also different, and the main roles of the two are different. And the way of generating electricity is also different.

1. The motor and generator are composed of magnets, coils, commutators, brushes, etc., and the link between the components is basically the same, and the components are connected in series by connecting the circuits in series.

2. There are magnets in the composition of the motor and the generator, so both will be affected by the direction of the magnetic field, and the direction of the current is related to the direction of the magnetic field, so the direction of the force of the coil in the motor and the generator is related to the direction of the magnetic field.

3. Their working principle is different, first of all, the generator is made according to the electromagnetic induction phenomenon, and the generator is made according to the principle of force movement of the energized conductor in the magnetic field, and secondly, the judgment method of the motor and the generator is different, the judgment of the current direction in the general generator usually uses the right-hand rule, and the direction of the conductor's force movement in the magnetic field in the motor is generally the left-hand rule.

4. The purpose of work and the conversion of energy are different, the generator generally needs to do work from the outside world, so as to convert mechanical energy into electrical energy, while the motor is the opposite, it needs to work on the outside world, so as to convert electrical energy into mechanical energy.

5. Summary: The structure is the same. The components are connected in the same way.

Each component is connected in series to form a circuit. All are affected by the direction of the magnetic field, and the direction of the current generated in the generator is related to the direction of the magnetic field; The direction of force on the coil in the motor is related to the direction of the magnetic field. The principle is different.

The method of judging is different. The purpose of work and the transformation of energy are different.

Hello! The generator is to charge the battery, and to charge the various electrical appliances, the drive motor must be rotated by the drive motor to work, it is possible to generate electricity, and there are other uses.

The difference is that one rotation produces electrical energy, and the other rotates through electrical energy.

First of all, the rotor of the large generator is also used to excite and enhance the magnetic force (the main role is to improve the efficiency of power generation, plus the relatively accurate control of the power generation), and the rotor will not produce current transmission to the given stator coil, but the stator coil will continue to cut the magnetic inductance line under the strong magnetic field and generate induced electromotive force. One last question: three-phase motors:

Three-phase stator windings (each with a difference of 120 degrees of electric angle), after the three-phase alternating current is introduced, a rotating magnetic field will be generated, and the rotating magnetic field will cut the rotor winding, thereby generating an induced current in the rotor winding**The sub-winding is a closed path) After the stator winding produces a rotating magnetic field, the rotor guide strip (squirrel cage bar) will cut the magnetic field lines of the rotating magnetic field and generate an induced current, and the current in the rotor guide strip interacts with the rotating magnetic field to produce electromagnetic force, The electromagnetic torque generated by the electromagnetic force drives the rotor to rotate in the direction of the rotating magnetic field at the speed of the rotating magnetic field.

The motor is an electrical appliance that works using the electromagnetic principle, and the engine is an internal combustion engine, which uses the high-pressure gas brought by oil combustion to push the piston to do external work.

Engine maintenance: For engines, lubricating oil is an important factor in protecting engine parts. Therefore, when the lubricating oil is started in cold climates, especially in the northern regions, if there is a lack of effective lubrication protection when starting the car, the engine will be worn, and it will cause high maintenance costs for a long time.

1. The cold car should be idle for a while when it is started. The amount of wear on the engine during cold start accounts for about half of the total wear. Normal idle warm-up can reduce this wear and tear and extend the life of the engine.

At low temperatures, the metal exhibits less elasticity and wear resistance; Only at operating temperatures can the engine achieve normal mating clearance and maintain optimal working condition.

2. The engine fuel system should be cleaned and maintained after 10,000 kilometers of normal driving, and there are two different cleaning methods: one is to add the "cleaning agent" directly to the fuel tank in a certain proportion and carry out internal circulation cleaning in the normal operation of the car; The other method needs to be supplemented by special equipment, which is cleaned when the engine is idling, and finally the decomposed carbon gelatinate is discharged with the exhaust gas.

3. Cleaning and maintenance of engine lubrication system. The cleaning agent is poured into the crankcase, and after 5 to 10 minutes of idling, the old oil is discharged from the imitation. At this time, the sludge, grease and carbon deposits in the lubrication system will be fully decomposed and discharged with the old oil, but it should be noted that the oil filter element must be replaced at the same time.

This cleaning and maintenance is suitable for use when changing the engine oil, and the oil protector can be added after cleaning, which can more effectively improve the service life of the vehicle parts and enhance the engine power).

4. Cleaning and maintenance of engine cooling system. This cleaning and maintenance can play a role in descaling, rust removal, rust prevention, and acid prevention, and the descaling rate can reach more than 85%. It's very easy to use

Simply add the "detergent" to the tank, clean it while the car is operating normally, and after a few hours, drain the waste water from the tank and re-add a new coolant or antifreeze. (Photo by Du Shifan, Pacific Automobile Standby Network).

It is an electric motor that works according to the principle of electromagnetism. The engine is an internal combustion engine, which uses high-pressure gases from oil combustion to push the piston to do work.

Engine maintenance: For engines, lubricating oil is an important factor in protecting engine components. Therefore, in cold climates, especially in northern regions, when starting the lubricating oil, if there is a lack of effective lubrication protection, the engine will wear out, and prolonged use will lead to higher maintenance costs.

1.Idle for a while when cold starting. Engine wear during cold starts accounts for about half of the total wear.

Warming up the car at normal idle speed can reduce this wear and tear and extend the life of the engine. At low temperatures, metals exhibit less elasticity and wear resistance; Only at the temperature of the working object can the engine achieve the normal fit clearance and maintain the best working condition.

2.When the engine travels normally for 10,000 kilometers, the fuel system of the engine should be cleaned and maintained. There are two main types of cleaning:

One is to add the "cleaning agent" directly to the fuel tank according to a certain proportion, and clean it in the internal circulation under the normal driving state of the car; Another way is that when the engine is idling, it needs to be cleaned with special equipment, and the final decomposed carbon colloids are discharged with the exhaust gases.

3.Cleaning and maintenance of the engine lubrication system. The cleaning agent is poured into the crankcase, idle for 5 to 10 minutes, and the old oil is drained.

At this point, the sludge, scale, and carbon deposits in the lubrication system will be fully decomposed and discharged with the old oil, but it is important to note that the oil filter must be replaced at the same time. (This cleaning and maintenance is suitable for oil change, and oil protector can be added after cleaning, which can effectively extend the service life of vehicle parts and enhance engine power.) )

4.Cleaning and maintenance of the engine cooling system. This kind of cleaning and maintenance can play the role of descaling, rust, rust and acid removal, and the descaling rate can reach more than 85%.

The operation is very simple: just add "cleaning agent" to the water tank and wash the car in normal operation. After a few hours, drain the wastewater from the tank and re-add new coolant or unfrozen liquid.

Millions of car purchase subsidies.
