Problems solved by technology

[0005] At present, in the motor, whether the stator or the rotor is located at the center of the motor, they are all solid structures. Therefore, the load driven by the motor must be arranged outside the motor, so that the drive of the motor and its driven load The size of the device is large, and it is difficult to meet the market demand for miniaturization
