Design of low-torque-ripple synchronous reluctance motors

Abstract
A design approach oriented to minimization of torque ripple is presented for synchronous reluctance motors of the transverse-laminated type. First, the possible types of rotors are classified and the more suited rotor structure is evidenced, to be matched to a given stator. Then, the inner rotor design is described, pointing out the low-ripple measures. Last, experimental results are given from three different rotors; they confirm the validity of the proposed approach. © 1998 IEEE
