Problems solved by technology

[0002] In the field of drive technology, in order to obtain low speed and high torque, the traditional method is to use a high-speed motor plus a reducer structure, in which the motor and reducer are connected by a hydraulic coupling. The disadvantages of this structure are : Large volume, high weight, high speed reduction ratio, serious mechanical loss, high noise and high vibration, high probability of system failure, complex installation and disassembly of the system, large amount of maintenance, and low system efficiency
[0003] With the continuous development of permanent magnet motors, low-speed and high-torque permanent magnet motors are used in this technical field, and the direct drive of permanent magnet motors with low speed and high torque is designed and produced, which solves the problem of low system efficiency and high noise in traditional methods. The problem of high vibration, but this kind of motor still has the disadvantages of large volume, high weight, complicated process and low cost performance
In addition, in the case of high torque, the braking of this kind of motor is difficult, the braking cost is high, and the volume of the braking system is too large, so this kind of motor or drive system cannot be applied to low-speed and high-torque applications in various industries. In transmission equipment, its application range is limited
