Analysis method using equivalent circuit considering harmonic components of pole change motor

This paper deals with the method of the characteristic analysis of the capacitor-run single-phase induction motor has two poles (4-pole and 2-pole). This motor, which is called pole change motor in this paper, is capable of variable speed operation without inverters or drives. However, speed-torque curve can be distorted by the harmonic components contained in the magnetic flux density distribution. Therefore, the characteristics of this motor are analyzed using equivalent circuit considering harmonic components and the simulation results are compared with the experimental results.
