This paper describes a surface permanent magnet (SPM)-type vernier motor that can generate high torque at low speeds, and a simple, high-speed method for analyzing its output characteristics is proposed. In this method, if the induced electromotive force, the synchronous reactance, and the iron loss are provided by finite element analysis (FEA), the output characteristics can be calculated immediately...
Surface permanent magnet-type vernier motors with three magnet array-type rotors (parallel magnetized type, repulsion type, and Halbach type) are compared based on the pull-out torque. It was clarified that increasing the rotor radius increases the pull-out torque at a fixed three-phase alternating voltage. The mechanism for the pull-out torque increase on each magnet array type was different, when...
