This paper investigates a new direct-drive machine, which artfully integrates a permanent-magnet brushless machine (PMBM) into a magnetic gear (MG). In order to achieve the capability of low speed operation and high torque output, the PMBM and MG share the same high-speed rotor. The key of the proposed machine is to adopt the Halbach permanent-magnet (PM) arrays and employ them to compose the PM poles...
In this paper, a new PM brushless hybrid machine is proposed and implemented for wind power generation. The key is to incorporate a small DC field winding and an extra air bridge so that the airgap flux can be effectively strengthened or weakened to online keep the output voltage constant throughout the whole wind speed range. Based on its magnetic circuit, it can be derived that a small change in...
The finite element-analytical method (FEAM) is newly proposed and implemented for analysis of practical machines with free rotation. A new analytical solution of the airgap region will be derived, which can naturally couple with the FEM equations of both the stator and rotor regions. The proposed FEAM will be verified by comparing with both FEM and experimental results based on practical PM brushless...
