Dynamic modeling of the circular winding brushless DC (CWBLDC) machine

A circular winding brushless DC (CWBLDC) motor is essentially a trapezoidal-EMF multiphase permanent magnet machine with the associated commutation circuit. It can achieve the same level of torque ripple performance as PMSMs, yet boast much higher torque density since the iron core is more fully utilized with trapezoidal EMFs. Field-circuit co-simulation is an effective and accurate tool in studying the operating principle of CWBLDC motors. However, it is too time-consuming. This paper thus proposes a dynamic model for the CWBLDC motor. A 10 kW, 8-pole, 46-slot, and 23-phase CWBLDC motor and associated commutation circuit has been modeled in the PLECS simulation environment. The simulation results agrees very well with field-circuit co-simulation and experimental tests, which verifies the precision of the proposed model.
