Description

Technical Field

[0001] The present application relates to the field of micro motors, and in particular to a high-performance micro motor with an adjustable magnetic field structure. Background Art

[0002] A micromotor, also known as a micro motor, is an electric motor with a small size and capacity, usually less than 160mm in diameter or a rated power of less than 750mW. They are widely used in control systems or transmission mechanical loads to realize the detection, analytical operation, amplification, execution or conversion of electromechanical signals or energy. A micromotor is a miniaturized electric motor with the characteristics of small size, light weight and high power density. It is widely used in various micro devices and systems, such as robots, automation equipment, medical equipment, aerospace and other fields. A micromotor is usually composed of a stator, a rotor and a control system. The stator is the fixed part of the motor, usually composed of a winding, an iron core and a casing. The rotor is the rotating part of the motor, usually composed of a permanent magnet, a shaft and bearings. The control system is responsible for controlling the operation of the motor, including speed, direction, torque, etc.
