Simulations and experiments on eddy current in Nd-Fe-B magnets
The eddy current loss of a Nd-Fe-B sintered magnet is estimated from temperature rise rate of their magnets. The obtained values of the eddy current loss coincide with the simulated data of the Integral Element Method. The method of dividing magnet is found effective in the suppression of the current loss. Also, it is observed that the higher harmonic effects on the alternating current are simple addition of each harmonics.
