A Small Low-Voltage High-Speed Consequent Pole Permanent Magnet Synchronous Motor Proposal for Vehicular Industries

Abstract

A small low-voltage high-speed Consequent Pole Permanent Magnet Synchronous (CP-PMSM) motor is proposed in this paper. The motor is suitable in various industries applications such as vehicular technology. The motor properties such as windings configuration and consequent pole structure are illustrated in the paper, where the motor dynamic is analyzed. The possible structure for teeth/poles combination is introduced by mathematical magnetic analysis and a sample one is proposed for vehicular applications. For this aim, a 400 Hz, 14 V CP-PMSM with 7 PMs in the rotor and 12 teeth in the stator is proposed as a 14-pole motor. Moreover, the motor performance under dynamic load is analyzed by Finite Element Method (FEM), where the motor efficiency, power capacity, and Power Factor (PF) are evaluated. Performed analysis for a new type PMSM with consequence pole structure is known as the paper novelties that are investigable for the researchers.
