The rare-earth permanent magnets adopted in transverse flux motors (TFMs) may cause manufacturing problems due to their strong magnetism as the motor size and output power increase. For example, large magnetic forces may attract ferrous debris during the process of handling and assembling, and, hence, increase manufacturing cost. To solve the aforementioned problems, this paper applies the subassembly magnetization (SAM) strategy for a TFM. Finite element analysis was employed to design the SAM fixture such that the desired magnetization can be achieved. The SAM approach is advantageous for manufacturing the presented TFM using a ring magnet as the rotor. Simulation results confirm that the permanent magnet of the TFM can be successfully magnetized.
