AI Technical Summary

Technical Problem

The overall operating efficiency of existing dual three-phase motors is low, making it difficult to fully unleash their performance potential.

Method used

The stator assembly employs a special layout design for the first and second windings, including multiple winding segments spaced apart along the circumference of the stator core. The adjacent winding segments are arranged to shorten the end length, optimize the magnetic field distribution, reduce leakage flux and electromagnetic losses, and are configured with independent multiphase windings to achieve power supply redundancy and dynamic optimization of the magnetic field.

Benefits of technology

It improves the efficiency and stability of the motor, enhances its reliability and fault tolerance, improves torque stability and load adaptability, and reduces resistance and copper loss.
