    Permanent-magnet synchronous motors (PMSMs) have higher efficiency than the conventional induction motors. The multiphase motors have smaller torque ripple and better fault-through performance than the conventional three-phase motors. In this paper, the speed control of five-phase PMSMs without sensing position is proposed. The provided experimental results demonstrate the proposed position sensorless control.

    In this paper, the speed control for two series-connected five-phase permanent magnet synchronous motors (PMSMs) is first proposed where both speeds of two five-phase PMSMs can be controlled independently without any position sensors. In first, the concept of the extended electromotive force (EEMF) developed for single motor is extended for two series-connected five-phase PMSMs. Some experimental results are provided to verify the proposed ISC.
