Abstract :
In high speed applications, the slotless permanent magnet motors appear an attractive solution, being almost intensitive to magneto-motive force harmonics and to pulse width modulation(PWM) current ripple and exhibiting lower stator iron losses and rotor losses (significant with square wave current control). In this paper, performance characteristic analysis of slotless synchronous motor/generator with Halbach array magnet will be dealt.
