چکیده
 This article proposes a new dual-sided permanent magnet (DSPM) machine with flux-concentrated U-shaped magnets (PMs) in stator, and consequent-pole PMs rotor, respectively. The proposed DSPM can perform bidirectional field modulation effect (BFME) to enhance the effective harmonics, hence improving torque capability. A magneto-motive force-permeance based model is employed reveal production mechanism. contributions of main-order working harmonics are identified quantified by employing hybrid finite-element (FE)/analytical method unified average equation. In order confirm merits design, basic electromagnetic characteristics configuration investigated compared those an existing stator PM design. Besides, further reduce cogging torque, parallel complementary design adopted for final prototyping. Finally, 6-slot/14-pole-pair prototype manufactured, some experimental measurements carried out validate theoretical FE analyses.

Induction Machine Drive with Dual Stator Winding
A new dual stator winding induction machine drive is described in this paper. The proposed induction machine consists of a standard squirrel-cage rotor and a stator with two separate windings wound for a dissimilar number of poles. Each stator winding is fed from an independent variable-frequency variablevoltage inverter. The proposed drive offers such advantages as speed sensor less operation,...

متن کاملA novel PM motor with hybrid PM excitation and asymmetric rotor structure for high torque performance
This paper proposes a novel permanent magnet (PM) motor for high torque performance, in which hybrid PM material and asymmetric rotor design are applied. The hybrid PM material is adopted to reduce the consumption of rare-earth PM because ferrite PM is assisted to enhance the torque production. Meanwhile, the rotor structure is designed to be asymmetric by shifting the surface-insert PM (SPM), ...
