High-speed Hollow Cup Motor belongs to DC permanent magnet Servo or control motor. It can also be classified as a micro motor. Hollow cup motor features in outstanding energy saving, Sensitive and convenient control and stable operating. As a highly efficient energy conversion device, it represents the development direction of electric motors in many fields.
Hollow cup motor breaks through the Rotor structure of traditional motor and use a coreless rotor, so it is also called coreless rotor. This novel rotor structure completely eliminates the loss of electrical energy due to eddy currents caused by iron core. At the same time, its weight and moment of inertia are greatly reduced, thereby reducing the mechanical energy loss of the rotor. Due to the structural changes of the rotor, the performance of the motor has been greatly improved. It not only has outstanding energy-saving features, but more importantly, it has the control and drag characteristics that the iron core motor cannot achieve.
Hollow cup motors are divided into brushed hollow cup motors and brushless hollow cup motors.
1. Energy conversion efficiency is very high, its maximum efficiency is generally above 70%, and some products can reach more than 90% (iron core motors are generally 70%).
2. Start and brake quickly, the response is extremely fast, the mechanical time constant is less than 28 milliseconds, some products can reach within 10 milliseconds (the iron core motor is generally more than 100 milliseconds); it can be conveniently operated under the high speed operation in the recommended operating area. The ground is sensitive to the speed.
3. The running stability is very reliable, the fluctuation of the speed is very small, and the fluctuation of the speed of the micro motor can be easily controlled within 2%.
