Problems solved by technology

There are a variety of air gap armature structure schemes in the prior art, some of which use all-composite support to support the stator coil and transmit torque, but the stiffness of the all-composite support is low, resulting in large circumferential displacement of the coil, causing Vibrates and damages the insulation; some use a combination of stainless steel teeth and composite material pads to fix the coil. Although the rigidity has been improved, the processing cost is expensive, and the installation process is complicated, which increases the difficulty of manufacturing
