Analysis of Torque Performance of Motor With Continuous Flat Wire
2021
This paper analyzes the torque performance of the flat wire motor, a potential winding form of a high-performance motor. The motor has continuous flat wire(CFW), so it has no solder joint in every branch, which improves the reliability. Besides, the axis length of end windings is shorter than that of the hairpin motor, so its power density is higher. However, the torque ripple and the cogging torque of the CFW motor are higher because of the larger slot opening. This paper compares the rotor skew and the stator chute, reduces the torque ripple and the cogging torque by the rotor skew.
