Abstract: Transverse flux permanent-magnet motor has the advantages of high torque density, but its torque ripple seriously affects the output torque characteristics. This paper proposes an improved direct torque control method. It increases the numbers of voltages vector and subdivides flux area, with redesigning switch table, changing the way of flux angle and the estimation models of stator flux and torque. So the switch frequency increases, and the model is more accurate. Finally, the motor can have a smooth operation for reducing torque ripple. It establishes the controlling system simulation model of transverse flux permanent-magnet motor, analyzes and compares with current hysteretic tracking control. The research results show that, the improved direct torque control reduces the torque ripple, and increases load torque and maximum value of speed, so that working performance of transverse flux permanent-magnet motor has been improved.
