Abstract: The current research on transverse flux motors is focused on and the achievements is introduced and analyzed from different perspectives, which provides strong reference values for future research. Firstly, it starts with the decoupling character about magnetic circuit and circuit in the transverse flux motor, pointing out that it can achieve higher torque density and power density than traditional radial flux motors and axial flux motors. It is easy for the motors to achieve low speed and high torque, which has good application prospects. Therefore, it has been highly valued by researchers in various countries. Secondly, the main types and basic structures of current transverse flux motors is introduced while their common patterns and individual differences summarized and analyzed among them. Thirdly, it is provided for the summary about such key technologies as its design and analysis methods, basic control strategies of drive systems, torque (or thrust) pulsation suppression, leakage suppression, and so on. It elaborates on various motor optimization methods, explores various fault-tolerant control strategies, and introduces the application of this motor system in transportation, industrial production, and military fields. Finally, the key areas that need to be studied for this motor system were discussed.
