The best two planetary gearbox speed control mechanisms: servo motors and stepper motors. What can be called an efficient planetary deceleration motor? Planetary gearbox motors used for high-energy electricity are referred to as high-efficiency planetary gear motors, or “high-efficiency motors” for short.
For the average motor, for every percentage point increase in efficiency, there is a significant increase in material, and when the efficiency of the motor reaches a certain value, no matter how much material is added, it cannot be increased. At present, most of the high-efficiency motors on the market are three-phase asynchronous motor replacement products, that is, its basic working principle remains unchanged.
5 features of high-efficiency planetary deceleration motors:
1. Add material: the use of increasing the iron heart outer diameter, iron heart length, ster groove size, copper wire weight and other methods, such as Y2-8024 motor from the current medium diameter to 130, some foreign increase of the length of the motor from 70 to 90. The iron consumption per motor increases by 3Kg and the copper wire by 0.9Kg.
2. The use of magnetically good silicon steel sheet, previously with large iron loss of hot-rolled sheet, now with high-quality cold-rolled sheet, low loss.
3. Improve processing accuracy, reduce mechanical losses to replace small fan to reduce fan losses using high-efficiency bearings.
4. The electrical performance parameters of the motor are optimized, and the motor parameters are optimized by changing the slot type and other methods.
5. Application of cast copper rouluts (complex process, high cost).
