Electromagnetic Design of a Dual-Consequent-Pole Transverse Flux Motor

In this paper, a dual-consequent-pole transverse flux motor and its electromagnetic design method are proposed. Both the stator and rotor of the proposed motor are designed to own the consequent-pole configurations. The unique motor structure improves the space utilization and the torque density. Firstly, the detailed structure and principle are introduced, and the development of the torque density of the proposed motor is discussed. Secondly, the electromagnetic design method's theory, considerations and flow process are listed. Then, the selections of some main structure parameters are proposed (e.g., pole-pitch, thickness of PMs and pole-arc coefficients of PMs). The electromagnetic performances of the proposed motor are compared with the existed transverse flux machines. At last, a prototype is manufactured and some primary experiments are done to verify and evaluate the proposed motor topology.
