What is a hollow cup motor? What is its principle and structure?
- Mar 23, 2018 -

Shenzhen Sinbad motor Co., Ltd. gear motor [gear motor: geared motor] from the gear box and the motor, the motor will be a very important part, today to tell you what is the hollow cup motor, and its principle and structure.


    First, the hollow cup motor: hollow cup motor belongs to DC, permanent magnet, servo micro motor. The hollow cup motor has outstanding energy-saving characteristics, sensitive and convenient control characteristics and stable operation characteristics. As a high-efficiency energy conversion device, it represents the development direction of the motor. The hollow cup motor breaks through the structural form of the rotor structure of the traditional motor, using a coreless rotor. The hollow cup motor has outstanding energy saving, control and drag characteristics.


    Second, the principle and structure of hollow cup motor

     Planetary Gear DC Coreless Motor


    The hollow cup motor breaks through the structure of the rotor structure of the traditional motor in the structure, using a coreless rotor, also known as hollow cup rotor.


    This novel rotor structure completely eliminates the power loss caused by the eddy currents of the iron core, while its weight and moment of inertia are greatly reduced, thereby reducing the mechanical energy loss of the rotor itself. Due to the structural changes of the rotor, the operating characteristics of the electric motor have been greatly improved, not only has outstanding energy-saving features, but more importantly, it has control and drag characteristics that can not be achieved by iron core motors.


    The hollow cup motor is divided into brushless and brushless type. The brushless hollow cup motor rotor has no iron core, and the brushless hollow cupless motor stator has no iron core.
