AI Technical Summary

Technical Problem

Traditional round wire motors suffer from increased copper losses and difficulty in heat dissipation due to the long winding end length. Furthermore, the air inside the slots occupies space, resulting in low conductivity, heat accumulation, and reduced lifespan of the insulation materials.

Method used

It adopts a rectangular slot with flat wire embedded in it and is equipped with insulating paper and partitions. Combined with the narrow slot and rotor V-shaped groove design, and with the elastic magnetic gap compensation structure, the magnetic circuit is optimized and efficient heat dissipation is achieved through a cooling device.

Benefits of technology

It improves the copper fill rate and current carrying capacity, reduces the risk of interlayer short circuits, optimizes magnetic field superposition and heat dissipation, and improves the efficiency and noise performance of the motor.
