摘要

The transient run-up performance of a three-phase induction motor with the Smith connection is investigated, with particular emphasis on the motor behavior at low-speeds. A time-stepping, coupled circuit, two-dimensional finite element method is used for the study, due account being made of magnetic saturation, harmonic and rotor deep-bar effects. It is found that short periods of speed reversal might precede motor run up. Besides, severe torque pulsations at low speeds could be produced when the motor is started at a zero-crossing instant of the supply voltage
