As we all know, there are many kinds of motor and each of them has a role to play in their specialized field. This article will introduce some motor that are used in industries and our daily life.
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 slow down the controlled component to achieve the purpose of control.
Servo motors are divided into DC and AC. The earliest servo motors are ordinary DC motors. When the control accuracy is low, ordinary DC motors are used as servo motors. The current DC servo motor is a low-power DC motor from a structural point of view.
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. So they have always been considered as the most ideal CNC machine tool actuators.
The stepper motor can also be used in other machinery, such as as the motor of the automatic feeder, as the general floppy disk drive motor, and can also be used in printers and plotters.
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.
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 highly regarded as traditional control motors and has a strong market potential.
The brushless DC motor features good mechanical and adjustment linearity, wide speed range, long life, easy maintenance, and low noise, so this kind of motor is broadly used in the control system.
DC motors have the advantages of good speed control performance, easy starting, and load-bearing starting. Therefore, DC motors are still widely used at present, especially after the appearance of SCR DC power supplies.
The asynchronous motor has the advantages of simple structure, convenient manufacture, use and maintenance, reliable operation, small size and low cost. Asynchronous motors are widely used in fields such as drive machine tools, water pumps, blowers, compressors, hoisting equipment, mining machinery, light industry machinery, agricultural and sideline products processing machinery, and many industrial and agricultural production machinery, household appliances and medical equipment.
They are also widely applied in household appliances, such as electric fans, refrigerators, air conditioners, vacuum cleaners, etc.
Synchronous motors are mainly used in 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 the main body. In addition, it can also be used as a tuning camera to deliver inductive or capacitive reactive power to the grid.
