The main purpose of the motor

1. Servo motor

Servo motors are widely used in various control systems, which can convert the input voltage signal into the mechanical output on the motor shaft, and drag the controlled element to achieve the control purpose.

Servo motors are divided into DC and AC. The earliest servo motors are general DC motors. When the control accuracy is not high, general DC motors are used as servo motors. In terms of structure, DC servo motor is a low-power DC motor, and its excitation mostly adopts armature control and magnetic field control, but usually adopts armature control.

2. Stepper motor

Stepper motors are mainly used in the field of CNC machine tool manufacturing. Since stepper motors do not require A/D conversion and can directly convert digital pulse signals into angular displacements, they have always been considered as the most ideal CNC machine tool actuators.

In addition to applications in CNC machine tools, stepper motors can also be used in other machinery, such as motors in automatic feeders, as motors in general-purpose floppy disk drives, and in printers and plotters.

3. Torque motor

Torque motors have the characteristics of low speed and high torque. Generally, AC torque motors are often used in the 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 is a new type of speed regulating motor with extremely simple and sturdy structure, low cost and excellent speed regulation performance. It is a strong competitor of traditional control motors and has strong market potential.

5. Brushless DC motor

The brushless DC motor has good linearity of mechanical characteristics and adjustment characteristics, wide speed regulation range, long life, easy maintenance and low noise, and there is no series of problems caused by brushes, so this kind of motor has a great role in the control system. great application.

6. DC motor

DC motors have the advantages of good speed regulation performance, easy starting, and the ability to start under heavy load, so DC motors are still widely used, especially after the emergence of thyristor DC power supplies.

7. Asynchronous motor

The asynchronous motor has the advantages of simple structure, convenient manufacture, use and maintenance, reliable operation, small quality and low cost. Asynchronous motors are widely used in driving machine tools, water pumps, blowers, compressors, hoisting and hoisting equipment, mining machinery, light industrial machinery, agricultural and sideline products processing machinery and most other industrial and agricultural production machinery, as well as household appliances and medical equipment.

There are many applications in household appliances, such as fans, refrigerators, air conditioners, vacuum cleaners, etc.

8. Synchronous motor

Synchronous motors are mainly used in large machinery, such as blowers, pumps, ball mills, compressors, rolling mills, and small and micro instruments or as control elements. Among them, the three-phase synchronous motor is its main body. In addition, it can also be used as a condenser to deliver inductive or capacitive reactive power to the grid.
