Usage For Electric Motor

1, servo motor

Servo motor is widely used in a variety of control systems, the input voltage signal can be converted to mechanical output on the motor shaft, dragging the control element, so as to achieve the purpose of control.

Servo motor has DC and AC, the first servo motor is a general DC motor, in the case of low control accuracy, only the general DC motor is used as servo motor. DC servo motor is a small power DC motor from its structure. Its armature is controlled by armature and magnetic field, but armature control is usually used.

2 、 stepping motor

The main application of stepping motor in the manufacture of CNC machine tools, the stepper motor A/D conversion is not required, can direct digital pulse signal into angular displacement, it has been regarded as the most ideal component of the NC machine tool.

In addition to the application of CNC machine tools, stepper motor can also be used on other machines, such as automatic feeding machine motor, motor as universal floppy drive, can also be used in printers and plotters.

3, torque motor

Torque motor has the characteristics of low speed and strong torque. AC torque motors are often used in textile industry, and their working principle and structure are the same as those of single-phase asynchronous motors.

4 、 switched reluctance motor

Switched reluctance motor (SRM) is a new type of variable speed motor. The structure is simple and firm, low cost and excellent speed regulation performance. It is a powerful competitor of traditional control motors, and has a strong market potential.

5 、 brushless DC motor

The mechanical characteristic of Brushless DC motor and regulation characteristics of good linearity, wide speed range, long service life, convenient maintenance and low noise, does not exist a series of problems caused by the brush, so this kind of motor has a great application in control system.

6 、 DC motor

DC motor has the advantages of good speed control, easy starting and load starting, so the application of DC motor is still very wide, especially after the SCR DC power supply appears.

7 、 asynchronous motor

Asynchronous motor has the advantages of simple structure, convenient manufacture, use and maintenance, reliable operation, small quality and low cost. Asynchronous motor is used widely in the driving machine, water pump, blower, compressor, lifting hoisting equipment, mining machinery, light industrial machinery, agricultural and sideline products processing machinery and machinery for the production of most workers and peasants household appliances and medical equipment etc..

It is widely used in household appliances, such as fans, refrigerators, air conditioners, vacuum cleaners, etc.. [3]

8. Synchronous motor

Synchronous motor is mainly used in large machinery, such as blowers, pumps, ball mills, compressors, rolling mills, as well as small, micro instruments, or acting as control components. Three phase synchronous motor is its main body. In addition, when the camera is used, the inductive or capacitive reactive power is transmitted to the grid.
