With the development of shipment synthesizing power technologies, the requirements on shipment propulsion motors. With the transfer of research focus on developing high compact direct drive propulsion motors, the machine transverse flux permanent magnetic motor solves the influence of resistance structure and magnet structure cross-effect of traditional motor on power density. This paper builds the mathematical model of permanent magnetic motor based on the features of transverse flux, designs the direct torque controller and builds the framework of the motor controller. This controller obtains the controlling parameters through magnet delay and directly controls the torque through dynamically regulating the drive voltage. The simulation and experiment results prove that the transverse flux permanent propulsion motor with direct torque controller has higher transient response speed.
