Abstract

This paper presents a simple method to calculate the stator surface vibration of a unipolar 4-phase hybrid stepping motor. The approximate radial magnetic force per pole is calculated by using a permeance model and its equivalent magnetic circuit. Based on the calculated radial magnetic forces and the measured stator mobility values, the radial vibration spectrum on top of a stator pole is estimated. The results have shown that there is a reasonable agreement between the calculated and measured radial vibration levels. This verifies the analytical approach which, due to the special structure and excitation of the motor, is significantly different from the technique commonly employed for vibration study for induction machines.
