1. Constant power wide speed range 2. Closed-loop control and servo control 3. Strong cutting force in low speed mode, and stable operation in high speed mode. 1. Smooth finish of workpiece surface. This 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 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. 3. 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. 4. European-style design and small sizes. The bar-type spindle motor can be used at the places with small radial space for spindle; given the same power, the sizes of spindle motor is 30% smaller than that of asynchronous motor. 5. Wide speed range. This motor has a wide range of speed regulation and achieves stepless speed regulating from zero-speed to maximum speed; the constant power ratio is 1:6.67. 6. High productivity. This motor has excellent rigid quality in low speed mode; therefore, it is applicable for rigid tapping. Within the rigidity limit of bearing and the hardness limit of cutter, the motor is applicable for low-speed & wide-engagement cutting or high-speed & small-engagement cutting; therefore, the efficiency of cutting hard metals is greatly increased. 7. Strong servo control. The motor has same functions as digital servo spindle when working with special drive. 8. Energy conservation. Given the same power, the energy conservation effect of spindle motor is 20%~50% greater than that of asynchronous motor. It has better energy conservation effect in case of greater power. 9. Wide applications. Depending on the rigid quality in low speed mode, the range of rotational speed of spindle motor is increased and the power ranges from 500W to 150KW.
