Grinding motor spindle / motorized

1. Constant power wide speed range
2. Closed-loop control and servo control
3. Enhance the smooth finish by grinding
Functions and Features
1. Smooth finish of workpiece surface. The motor has excellent speed rigid quality and maintains high rotational speed stability even in case of fluctuation of load, therefore, it enhances the smooth finish of workpiece surface.
2. Slight transmission error. The length of main driving chain is zero and the spindle is directly driven by the motor which achieves zero-error transmission and weakens spindle vibration, therefore, it enhances the smooth finish of workpiece surface.
3. Slight deformation of spindle. The rotor is made of rare earth permanent magnet, and it is free of exciting current and generates little heat. The spindle has good axial stability, therefore it achieves high machining precision.
4. Power and torque large. This rare earth permanent magnet motor has high power density and torque density. Given the same volume, the power and torque of this spindle motor is one grade higher than that of asynchronous motor. Given the same power, the torque is greatly larger than that of asynchronous motor, since the former is free of exciting current.
5. Rear direct drive and flexible combination. The motor is at the end part of the spindle, the motor power and spindle weight and length can be arbitrary collocation. This flexible combination is fit for the places with small radial space for spindle.
6. Wide speed range. The motor has a wide range of speed regulation and achieves stepless speed regulating from zero-speed to maximum speed; the constant power ratio is 1:1.25.
