The working process and application direction of the motor

The working process of the motor mainly involves the conversion between electrical energy and mechanical energy, and its core principle is based on the law of electromagnetic induction. In the motor, the current is passed through the stator winding to generate a rotating magnetic field, which interacts with the rotor winding to generate electromagnetic torque, thereby rotating the motor. Specifically, the stator winding generates a rotating magnetic field, and the rotor winding cuts the magnetic flux lines in the magnetic field to generate induced current, which in turn forms an electromagnetic torque to drive the rotor to rotate.

The application direction of the motor is extremely wide, covering almost all fields that require power output. According to the purpose, the motor can be divided into two categories: drive motors and control motors.

Drive motors are mainly used to provide power, such as power tools (drilling, polishing, etc.), household appliances (washing machines, electric fans, etc.), and other general small mechanical equipment (small machine tools, medical equipment, etc.).
Control motors are more used for precise control, such as stepper motors and servo motors, and play an important role in automatic control systems.
In addition, motors are also classified in many ways according to different types of working power supplies, structures and working principles, starting and operating methods, rotor structures, and operating speeds, to meet the needs of different fields and application scenarios. For example, DC motors and AC motors are widely used in industrial production; high-speed motors and low-speed motors are selected and used according to specific work requirements.
