Design of surface permanent magnet-type vernier motor

Abstract

In this paper, the authors designed a surface permanent magnet (SPM)-type vernier motor whose maximum output is more than 5.2 kW, whose power factor at 4 kW is more than 90%, and whose efficiency at 4 kW is 85% under the conditions that the operating voltage, frequency, and synchronous speed are 400 V, 50 Hz, and 100 min-1, respectively.
