Abstract
- A novel approach to quickly evaluate the electromagnetic vibration emitted by a permanent-magnet synchronous machine in A fractional-horsepower drive is detailed. Field reconstruction method and mechanical impulse response are used. The impulse response for rapid evaluation of vibrations at critical points is used after the design of a torque and speed controller. The vibration obtained using a three-phase pulsewidth-modulation technique and nonclassic space-vector modulations are compared by simulation results. An optimal choice of the carrier frequency, by an optimization method, for the two modulation techniques allows for a 35% reduction of the vibration in the targeted machine under different operating conditions. The peak-to-peak force-magnitude reduction reaches 8%. [ABSTRACT FROM PUBLISHER]
