Abstract：Transverse flux permanent magnet motor has a spatial decoupling between electric load and magnetic load, and features with flexible design and higher torque density. So this motor is suitable for low speed high torque field. In this paper a bidirectional crosslinking transverse flux tubular linear permanent magnet synchronous motor(BCTF-TLPSM) is presented, which can fully utilize secondary permanent magnets and have larger space utilization ratio than traditional transverse flux machine. The structure and principle of this motor is introduced. Based on the basic electromagnetic relations and the 3D finite element analysis model of the BCTF-TLPMSM, a set of feasible design method is summed up. A prototype is designed and manufactured. The no-load back-EMF and static thrust experiments are carried out. The theoretical analyses agree with the experiment results well. That verify the validity of the theoretical analysis as well as the rationality of motor design.
