Principle and structure of hollow cup motor

1. Principle: The hollow cup motor breaks through the traditional rotor structure of the motor in the structure of the rotor form, using the coreless rotor, also known as the hollow cup rotor. This rotor structure completely eliminates the formation of eddy current due to the iron core and the loss of electrical energy, while its weight and moment of inertia is greatly reduced, thus reducing the rotor's own mechanical energy loss. The hollow cup motor belongs to DC, permanent magnet, servo micro motor.

2. Characteristics: hollow cup motor has outstanding energy-saving characteristics, sensitive and convenient control characteristics and stable operation characteristics, as a high-efficiency energy conversion device, represents the direction of motor development.

3. Classification: hollow cup motor is divided into brush and brushless two kinds, brush hollow cup motor rotor without iron core, brushless hollow cup motor stator without iron core.
