AI Technical Summary

Technical Problem

The manufacturing cost of existing magnetoresistive motors is high, mainly due to the need to use special processing equipment and expensive rare earth materials.

Method used

A reluctance motor including a stator assembly, a rotor assembly and a control circuit board is designed. The stator assembly adopts a stator punch and a coil frame structure, which is removably connected, simplifying the coil installation process; the control circuit board is integrated at the tail end of the rotor shaft, reducing the overall volume and complexity of the reluctance motor.

Benefits of technology

By simplifying the manufacturing process of the stator assembly, the dependence on special equipment is reduced, the manufacturing cost and steps are reduced; the integrated design of the control circuit board reduces the motor volume, improves service life, and solves the problem of messy line connections.
