Abstract

The results of the loss measurements of some rare-earth permanent magnets in a. c. magnetic field are presented. The losses are consisted of the eddyurrent losses and the hyteresis losses of the magnets itselves and the eddy-current losses of the metal coatings. The hysteresis losses occur in Sm₂Co₁₇ type ones. These data can be applied for estimating the tooth-ripple losses of the motors with permanent magnets on the pole surfaces, and for discussing the flux loss under the motor flux condition.
