Abstract
Magnetic frequency characteristics of permanent magnet for arc-shaped PM motor are shown, because harmonics components of magnetic flux density is supplied to PM, and the loss increase is expected. Stator core shape of PM motor makes slot harmonics components, and PWM inverter to magnetize the stator core makes time harmonics components. Numerical calculation shows that NdFeB sintered magnet has a large loss because of large eddy current in permanent magnet, though NdFeB bonded magnet has much smaller, because of 100 times smaller electrical conductivity.
