| 1. Servo motor Servo motors are widely used in various control systems. They can convert the input voltage signal into a mechanical output on the motor shaft and drag the controlled components to achieve the purpose of control. Servo motors are divided into DC and AC. The early servo motors were ordinary DC motors. When the control accuracy is not high, ordinary DC motors are used as servo motors. Structurally speaking, a DC servo motor is a low-power DC motor. Its excitation mostly uses armature control and magnetic field control, but armature control is usually used. 2. Stepping motor Stepping motors are mainly used in the field of CNC machine tool manufacturing. Because stepping motors do not require A/D conversion and can directly convert digital pulse signals into angular displacements, they have always been considered as ideal CNC machine tools. In addition to the application on CNC machine tools, stepper motors can also be used in other machinery, such as as the motor in automatic feeders, as the motor of general floppy disk drives, and can also be used 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 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 a strong market potential. 5. Brushless DC motor The brushless DC motor has good mechanical characteristics and adjustment characteristics linearity, wide speed range, long life, easy maintenance, low noise, and no series of problems caused by brushes. Therefore, this kind of motor has a lot of advantages in the control system. Big application. 6. DC motor DC motors have the advantages of good speed regulation performance, easy starting, and ability to start under load. Therefore, DC motors are still widely used, especially after the appearance 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 to drive machine tools, water pumps, blowers, compressors, hoisting equipment, mining machinery, light industrial machinery, agricultural and sideline products processing machinery, and most industrial and agricultural production machinery, as well as household appliances and medical equipment. There are many applications in household appliances, such as electric fans, refrigerators, air conditioners, vacuum cleaners, etc. 8. Synchronous motor Synchronous motors are mainly used for large-scale machinery, such as blowers, water pumps, ball mills, compressors, rolling mills, and small and micro instruments or as control components. Among them, the three-phase synchronous motor is its main body. In addition, it can also be used as a tuning camera to deliver inductive or capacitive reactive power to the grid. |
