What are the applications of motors? What are the main functions of the motor?

There are many kinds of motors, all of which are used in different places!

For example, air conditioners, fans, washing machines, and *** and computers, many, many more.

There are different types of motors, which are used as power units for different household appliances and industrial machinery.

Motors are used in a wide range of applications.

Needless to say, ordinary factories are not to mention.

I'll list some of the others, architecture, healthcare, office.

Because computers also need motors, there are motors wherever they are used.

The average household has at least 10 motors.

Applications where power is to be generated.

As long as it is about turning, it will be used.

Electric machinery (commonly known as "motor") refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction.

The function of the electric motor: to convert the electrical energy of the battery into mechanical energy to drive the wheels of the electric vehicle to rotate, so as to achieve the purpose of continuous riding of the electric vehicle.

When the motor is working, the coil and commutator rotate, the magnet and the carbon brush do not rotate, and the alternating change of the current direction of the coil is completed by the commutator and the carbon brush that rotate with the motor. The strength of the brushed motor is greater than that of the brushless motor, and there are fewer wires, just a positive and negative and a negative pole wire. If the motor is reversed, it can be done by simply reversing the positions of the two wires.

In the electric vehicle industry, brushed motors are divided into high-speed brushed motors and low-speed brushed motors. There are many differences between brushed motors and brushless motors, and the easiest way to distinguish them is: brushed motors have carbon brushes, and brushless motors do not have carbon brushes.

However, the brush motor is noisy, and the brush motor has been basically eliminated.

Common types of motors are: brushed toothed high-speed hub motor, brushed toothless low-speed hub motor, brushless toothless low-speed hub motor, brushless toothed high-speed hub motor, side-mounted motor, etc.

The motor is an electromagnetic device, and its main role is to generate power and decelerate.

Motor refers to an electromagnetic device that converts or transmits electrical energy according to the law of electromagnetic induction. Includes electric motors and generators.

What it does:

1.The main function of the electric motor is to generate driving torque, which is used as a power source for electrical appliances or various machinery.

2.The main role is to use mechanical energy to convert into electrical energy, and the most commonly used at present is to use heat energy, water energy, etc. to push the rotor of the generator to generate electricity.

There are many forms of motors, but their working principles are all based on the laws of electromagnetic induction and electromagnetic forces. Therefore, the general principle of its construction is to use appropriate magnetic and conductive materials to form magnetic circuits and circuits that carry out electromagnetic induction with each other, so as to generate electromagnetic power and achieve the purpose of energy conversion.

According to the different starting and operation modes of the motor, it can be divided into capacitive starting single-phase asynchronous motor, capacitive running single-phase asynchronous motor, capacitor starting single-phase asynchronous motor and split-phase single-phase asynchronous motor, three-phase motor.

According to the structure of the motor, it can be divided into cage induction motor, which is the one you are using (the old standard is called squirrel cage asynchronous motor) and the wound rotor induction motor (the old standard is called the wound asynchronous motor). A squirrel cage is a closed coil.

1) When the three-phase asynchronous motor is connected to the three-phase AC power supply (each with a difference of 120 degrees of electric angle), the three-phase stator winding flows through the three-phase symmetrical current to generate the three-phase magnetodynamic potential (stator rotation magnetodynamic potential) and generate a rotating magnetic field, which rotates clockwise along the inner circular space of the stator and rotor at a synchronous speed.

2) The rotating magnetic field has a relative cutting motion with the rotor conductor, and according to the principle of electromagnetic induction, the rotor conductor (the rotor winding is a closed path) generates an induced electromotive force and an induced current (the direction of the induced electromotive force is determined by the right-hand rule).

3) According to the law of electromagnetic force, under the action of induced electromotive force, an induced current will be generated in the rotor conductor that is basically consistent with the direction of the induced electromotive force. The current-carrying rotor conductor is subjected to electromagnetic force in the magnetic field generated by the stator (the direction of the force is determined by the left-hand rule), and the electromagnetic force forms an electromagnetic torque on the motor rotor shaft, which drives the motor rotor to rotate along the direction of the rotating magnetic field, and when the motor shaft is mechanically loaded, it outputs mechanical energy outward. Since the magnetic flux of the part without a short-circuit ring is superior to that of the part with a short-circuit ring, the direction of rotation of the motor is the same as that of the rotating magnetic field.

Its main role is to generate driving torque, as a power source for electrical appliances or various machinery, its main role is to use mechanical energy to convert into electrical energy, and the most commonly used at present is to use thermal energy, water energy, etc. to drive the generator rotor to generate electricity.

The function of the motor is to convert the electrical energy of the power supply into mechanical energy, and the working device that directly drives the car through the transmission device or directly drives the car. However, due to the commutation spark, the DC motor has low power, low efficiency and leakage rate, and large maintenance workload;

2.With the development of motor control technology, it is bound to be gradually replaced by brushless DC motors (BLDCM), switched reluctance motors (SRM) and AC hand-operated asynchronous motors. Hope.

The function of the motor is to convert electrical energy into kinetic energy through the principle of electromagnetic conversion, which is really helping you look forward to it

The machine tools in the machinery manufacturing plant, from the traditional lathes, milling machines, planers, grinding machines, stamping machines, to modern CNC machine tools and automatic production lines, all use Shen electric motors as power. The auxiliary equipment such as the crane and the fingers in the workshop are all powered by the motor. Even some hydraulic equipment has an oil pump driven by an electric motor.

The most commonly used gantry milling machine in Dali Machinery Processing Factory is a motor that drives the rotation of each milling cutter, in fact, there are many other motors in this cavity infiltration table machine tool, such as the motor that drives the bed blood reciprocating and the beam lifting motor. Screw motors for horizontal turret transverse motion and vertical turret longitudinal motion, motors for horizontal turret vertical motion and vertical turret horizontal motion and cooling water pump motor, etc.
