摘要: This invention relates to a harmonically graded airgap reluctance-type rotating electric resolver. The magnetic permeance of the airgap is made to vary sinusoidally. Therefore, only the fundamental wave exists, free of higher harmonics. The invention has application in numerous fields, including commutation of brushless motors and to precisely position machinery tools relative to work pieces in numerically controlled machines.
