What is the difference between a high temperature motor and an ordinary motor?

Compared with ordinary motors, high-temperature motors adopt advanced design technology, made of high-temperature resistant insulating materials, it can ensure the safe operation of the motor in a high-temperature environment, no aging, no burning, although there are not many domestic enterprises producing high-temperature motors, but the application range of high-temperature motors is wide, and the market prospect is promising. Its motor performance is designed according to the characteristics of fan pump loads, which can save energy and insulate structure. The use of reinforced insulation, can be long-term in the high temperature and high humidity wood precipitation water vapor atmosphere environment continuous forward and reverse cycle operation, so as to ensure reliable insulation and improve the service life, the motor adopts keyway type and threaded type, which is convenient for the loading and unloading of fan impellers; In order to improve its own waterproof steam and wood dust resistance.

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

In the circuit it is indicated by the letter M (D in the old standard). Its main function is to generate driving torque, as a power source for electrical appliances or various machinery. Generators are denoted by the letter G in the circuit.

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 push the generator rotor to generate electricity.

What is a high-voltage motor and what is the difference between it and an ordinary motor? Today is a long time to see.

A high-temperature motor generally refers to a motor that operates beyond the allowable temperature of the motor. The difference is that the internal structure of the motor, as well as the material, are different. The mechanical structure is also different from the motor winding material. **Also relatively high.

There are generally two reasons for the high working noise of the motor, one is the mechanical noise, mainly the wear of the motor bearing and the lack of oil, resulting in hard friction noise. For this, it can be cleaned and grease added to reduce noise. When the rotor shaft and bearing are loose or the end cover is loose, it will also cause the motor to produce axial channeling noise when rotating.

There are also some motors with poor assembly quality, the bearing chamber is not concentric, and the radial clearance of the motor is uneven, which will produce abnormal noise. In this regard, as long as the outer cover and the rear inner cover are removed, the rotor and stator seat are removed, and the central shaft of the riveting inner cover can be re-knocked on to repair in an emergency.

In addition, some shaded pole motors have loose short-circuit rings or loose cores that produce electromagnetic noise, and clamping measures should be taken. Shoupu high temperature motor is good.

The reasons for the excessive temperature of the motor are analyzed as follows:

1.There is a short circuit between the turns of the motor winding, between the phase windings, and between the windings and the grounding resistance, so that the current in the winding increases sharply, and the temperature is too high.

2.The insulation between the core pieces of the motor is damaged, which increases the eddy current loss in the iron fiber quietly, and the temperature is too high due to the sharp increase in the core heating.

3.When the three-phase motor works out of phase, the current in the other two-phase winding increases, resulting in the winding temperature being too high, and when the single-phase motor starts the winding is broken, the temperature of the main winding will be too high due to the same destruction of the slag-resistant sample.

4.The long-term operation of the motor under the condition of overload will also cause the current around the mu hall to be too large, so that the heating of the winding will increase and the temperature will be too high.

5.If the motor starts too frequently, because the current at the start is more than 2 times the normal working current, it will also cause the heating of the winding to increase and cause the temperature to be too high.

6.The electrical contact of the motor is poor, which increases the heat at the connecting parts and causes the temperature to be too high.

7.When the grid voltage is too high or too low, the current in the motor windings increases, resulting in heat generation and high temperature.

8.When the bearing of the rotating part is damaged or lacks oil, the friction of the rotating part increases or the temperature is too high due to impact.

9.The heat dissipation part of the motor is faulty or the ventilation duct is blocked, resulting in excessive temperature.

10.The ambient temperature of the motor is too high when it is working.

In the case of the rated load, the temperature of the shell is generally not higher than 80 degrees, and the normal temperature is about 60 or 70 degrees.

If the temperature of the measured motor cover exceeds the ambient temperature by more than 25 degrees, it indicates that the temperature rise of the motor has exceeded the normal range, and the temperature rise of the general motor should be below 20 degrees. Generally, the motor coil is wound by enameled wire, and when the temperature of the enameled wire is higher than about 150 degrees, the paint film will fall off due to the high temperature, resulting in a short circuit of the coil.

Compound excitation DC motorIn addition to the parallel excitation winding, the stator pole is also equipped with a series excitation winding that is connected in series with the rotor winding (its number of turns is less). The direction of the magnetic flux generated by the series winding is the same as that of the main winding, the starting torque is about 4 times of the rated torque, and the short-term overload torque is about twice the rated torque. The speed change rate is 25% to 30% (related to the series winding).

The rotational speed can be adjusted by attenuating the strength of the magnetic field.

It will ruin the high temperature will ruin the motor.

The difference between a high-temperature motor and a normal motor is that they are capable of withstanding the highest temperature differently.

Generally speaking, the maximum operating temperature of ordinary motors is between 80 and 120 degrees Celsius, while the maximum operating temperature of high-temperature motors can reach more than 200 degrees Celsius and even as high as 400 degrees Celsius. High-temperature motors are generally designed with special materials and structures to ensure their stability and durability in high-temperature environments.

In addition, high-temperature motors also differ in terms of insulation, bearings, lubrication, and heat dissipation. In a high-temperature environment, the motor insulation material needs to use special high-temperature insulation materials, the bearing needs to use high-temperature shaft residual bearing or special lubricants, and the motor structure also needs to be optimized to improve heat dissipation efficiency and prevent overheating from causing failure.

In short, a high-temperature motor is a motor specially designed to operate in a high-temperature environment, with higher temperature resistance and stronger adaptability to meet the needs of special industrial applications.

First, the nature of the motor is different.

1. Plateau motor: It is a motor with an altitude of more than 1000 meters.

2. Ordinary motor: It is an electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction.

2. The applicable conditions are different.

1. Plateau motor: Plateau motor requires operation under harsh conditions such as high altitude, low air pressure, lack of oxygen, high cold vertical hail, large temperature difference, and large wind and sand, so plateau motor needs a higher insulation level, good ventilation and heat dissipation structure, as well as motor anti-vibration, anti-sand and other structures.

2. Ordinary motor: The normal ambient temperature of the general motor is -5 to 40, and the location should be below 1000m above sea level.

The high-efficiency and energy-saving motor adopts new motor design, new process and new materials to improve the output efficiency by reducing the loss of electromagnetic energy, thermal energy and mechanical energy. Compared with ordinary motors, the energy saving effect of using high-efficiency motors is very obvious, and the efficiency can be increased by an average of 5% under normal circumstances.

Use of high-efficiency and energy-saving motor features:

1. Save energy and reduce long-term operating costs, which is very suitable for textile, fan, water pump, compressor, and air conditioner.

2. Start directly or use the inverter to adjust the speed, and the asynchronous motor can be fully replaced.

3. The rare earth permanent magnet high-efficiency and energy-saving motor itself can save more than 15 electric energy compared with ordinary motors.

4. The power factor of the motor is close to 1, which improves the quality factor of the power grid, and there is no need to add a power factor compensator.

5. The motor current is small, which saves the transmission and distribution capacity and prolongs the overall operating life of the system.

The difference between high-efficiency motor and ordinary motor is mainly reflected in the following aspects:

Different efficiency values: The efficiency value of high-efficiency motors is generally higher than that of ordinary motors, which means that under the same working conditions, high-efficiency motors can convert electrical energy into mechanical energy more efficiently, thereby reducing energy waste.

Different running characteristics: High-efficiency motors typically have lower noise and higher efficiency during operation, so they can run longer and can withstand higher loads. In contrast, regular motors are typically less noisy and less efficient and need to be replaced more frequently to keep them up and running.

Different material consumption: High-efficiency motors are usually manufactured with more high-quality materials to guarantee higher performance. This means that high-efficiency motors are typically more expensive than regular motors and require more maintenance and upkeep.

Different costs: High-efficiency motors are usually more expensive than ordinary filial piety motors, so the initial cost and long-term operating costs need to be considered when purchasing and replacing motors.

Different application areas: High-efficiency motors are often suitable for more demanding applications such as industrial, aerospace, medical devices, etc., as they require higher reliability and performance. Ordinary motors are more widely used in household appliances, power tools, automobiles and other fields.

High-voltage motors are distinguished by high and low voltages. For example, more than 1000V is considered to be a high-voltage motor, and 380V and 660V are low-voltage motors.

Ordinary motors refer to relatively special motors. Such as dragging electric motors for pumps, fans, compressors, crushers, etc.

Special motors such as marine, flameproof, traction, diving, etc. Most of the high-voltage motors are ordinary motors. There are many ordinary motors, and the motors are high-voltage motors.

High-voltage motor refers to a motor with a rated voltage of more than 1000V. Commonly used are 6000V and 10000V voltages, due to different foreign power grids, there are also 3300V and 6600V voltage levels.

The high-voltage motor is generated because the motor power is proportional to the product of voltage and current, so the power of the low-voltage motor increases to a certain extent (such as 300kw 380v) and the current is limited by the allowable bearing capacity of the wire, which is difficult to make larger, or the cost is too high. It is necessary to increase the voltage to achieve high power output. The advantages of high-voltage motor are high power and strong impact bearing capacity; The disadvantage is that the inertia is large, and it is difficult to start and brake.
