motorMotor is a kind of electromagnetic device that realizes the conversion or transmission of electric energy according to the law of electromagnetic induction, or converts one form of electric energy into another form of electric energy. An electric motor converts electrical energy into mechanical energy (commonly known as a motor), and a generator converts mechanical energy into electrical energy. An electric motor is denoted by the letter "M" (or "D" in the old standard) in a circuit. Its main function is to produce driving torque, as the power source of electrical appliances or various machinery.

The rotor speed of an asynchronous motor is always slightly lower than the synchronous speed of the rotating magnetic field.
The rotor speed of a synchronous motor is independent of the size of the load and is always maintained at a synchronous speed.
Main applications
1, servo motor
Servo motor is widely used in various control systems, can be converted into the input voltage signal on the motor shaft of the mechanical output, dragging the controlled components, so as to achieve the purpose of control.
Servo motor has a DC and AC points, the earliest servo motor is a general DC motor, in the case of control precision is not high, before the use of general DC motor as a servo motor. The current DC servo motor from the structure, is a small power DC motor, its excitation more armature control and magnetic field control, but usually use armature control.
2, stepper motor
Stepper motor is mainly used in the field of CNC machine tool manufacturing, due to the stepper motor does not require A/D conversion, can be directly converted to digital pulse signals into an angular displacement, so it has been regarded as the ideal CNC machine tool actuating elements.
In addition to their use in CNC machine tools, stepper motors can also be used in other machinery, such as as motors in automatic feeders, as motors in general-purpose floppy disk drives, and in printers and plotters.

Switched reluctance motor is a new type of speed motor, the structure is extremely simple and strong, low cost, excellent speed performance, is a strong competitor of the traditional control motor, has a strong market potential.
5, brushless DC motor
Brushless DC motor mechanical characteristics and regulating characteristics of good linearity, wide speed range, long life, easy maintenance and low noise, there is no brush caused by a series of problems, so this motor in the control system has great applications.

Asynchronous motor has a simple structure, manufacturing, easy to use and maintenance, reliable operation and smaller quality, lower cost and other advantages. Asynchronous motor is widely used to drive machine tools, pumps, blowers, compressors, lifting and winching equipment, mining machinery, light industrial machinery, agricultural and sideline product processing machinery and most of the industrial and agricultural production machinery, as well as household appliances and medical equipment.
In the household appliances in the application of more, such as fans, refrigerators, air conditioners, vacuum cleaners and so on.
8, synchronous motor
Synchronous motor is mainly used for large machinery, such as blowers, pumps, ball mills, compressors, rolling mills, and small, micro-instrumentation or as a control element. Three-phase synchronous motor is the main body. In addition, it can also be used as a regulator to deliver inductive or capacitive reactive power to the grid.
