Abstract:
 An axial coil assisted reluctance doubly salient motor was designed for the problem that the permanent agnet might demagnetize and could not be magnetized under high temperature and high pressure  permanent magnet DC motor. According to the principle of the double salient motor,based on the special tructure and inductance model of the motor,a three phase six-state angle conduction mode was put orward on the basis of the standard angle conduction mode. An excitation current-torque direct control trategy based on the central excitation coil with a two-group power inverter module was proposed. By controlling he excitation current at the commutation moment to realize the adaptive adjustment of the excitation urrent the torque control was achieved. Ultimately the feasibility and effectiveness of the control ethod making the motor run more smoothly are verified by the field-circuit coupled analysis and experiments.
