Abstract

Abstract: A novel structure of Veriner permanent magnet (VPM) machine is presented as an effective option for high torque density direct-driven applications. The key is to locate PMs on both sides of rotor and stator, and design the stator PMs as a cylinder shape, the rotation of which can be controlled by an external driven system. With this design, magnetic field in the airgap can be directly regulated by the rotation of stator PMs. The structure and operation principle are introduced and the performance is analyzed with time-stepping finite element method (FEM). Analysis results show that the novel structure has really high torque density and good field weakening performance.

Key words: Directly-driven, finite element method, flux modulation, high torque density, permanent magnets
