The shaded-pole reduction motor is a common type of motor, mainly composed of the following parts:

1. Permanent magnet rotor: The rotor part is made of permanent magnets, which concentrates the magnetic field in a small range and increases the torque of the motor.

2. Stator winding: The stator winding generates a rotating magnetic field to drive the rotor to rotate.

3. Gear reduction mechanism: Mechanical deceleration is achieved through a set of planetary gear sets, which greatly reduces the speed of the motor output shaft and increases the output torque.

The working principle of the shaded-pole reduction motor is as follows:

1. The stator winding generates a rotating magnetic field, which interacts with the rotor permanent magnet.

2. The rotor rotates driven by the rotating magnetic field.

3. The gear reduction mechanism converts the high-speed and low-torque motor output into a low-speed and high-torque output.

This structural design makes the shaded pole reduction motor have the following advantages:

- High torque output

- Compact size

- Low noise and vibration

- Long life

Shaded pole reduction motors are widely used in robotic arms, industrial robots, power tools and other occasions that require high torque and low speed drive. I have briefly explained the basic principles and characteristics of shaded pole reduction motors. If you have other questions, please continue to ask me.
