Abstract

This paper investigates a method of reducing vibration property of a permanent-magnet synchronous motor (PMSM) with dual three-phase windings, especially focusing on carrier harmonic component. Carrier phase shift pulse width modulation (PWM) which makes any difference between PWM carrier phase of 1st winding and 2nd winding, is applied to 24-slot 20-pole PMSM. A tested motor is manufactured and measured results reveals the vibration and sound pressure can be approximately halved at around twice of the carrier frequency when the carrier phase is π/2 radian between each three-phase winding compared to conventional in-phase carrier PWM.
