Abstract

A Pseudo direct-drive (PDD) machine with Halbach consequent-pole in stator opening is proposed and researched in this paper. To explain the operation principle, the proposed PDD machine is regarded as a flux reversal machine combining with a regular PMSM, and the electromagnetic torque is analytically derived. To study the influence of magnetic circuit on the torque performance, proposed machines with different inner PM rotor are built and compared with FEA methods. At last, an 18 slots 8 poles PDD machine is built and the superiority of Halbach consequent-pole to regular consequent pole is validated. Due to the reduction of flux leakage, the flux density of working harmonics increases in the outer airgap. Results shows that PDD machine with Halbach consequent pole reaches 4% higher EM torque and 43% higher pull-out torque than regular consequent pole PDD machine.
