Abstract
This paper presents numerical simulations of the speed and torque control of a polyphase brushless DC motor prototype. The machine was built using distinctive design characteristics, which contains 12 armature phases and a nominal power of about 30 kW. In order to reproduce the behaviour of the conventional DC motors, a "slot by slot" commutation technique has been considered. The magnetic field distribution has a trapezoidal shape and therefor no d-q transformation is used in the numerical model. The machine model, the speed and the torque control system are presented and discussed in detail. The torque and current phenomena, which have been observed in the hysteresis control method, are analysed and the advantages and disadvantages of this approach are highlighted. Simulation results are satisfactory and they show that the numerical model as well as the control system employed are reliable.
