AI Technical Summary
Technical Problem
The rotational speed stability of the existing motor rotor is low, and the carrier structure requires large radial space, resulting in increased manufacturing costs.
Method used
Using non-thin plate-shaped rotor shaft material and integrating carrier into the rotor shaft, the precise alignment and firm anchoring of the convex poles are achieved through the design of anchor shoulders and anchor grooves, reducing the fastening steps and improving Speed stability.
Benefits of technology
Improves speed stability, reduces manufacturing costs, reduces the fastening steps of the carrier, and achieves a higher radial anchoring effect.
