Abstract A circular winding brushless DC (CWBLDC) machine is a multiphase brushless dc machine with the associated commutation circuit. It can achieve higher torque density than permanent magnet synchronous machines (PMSMs) since the iron core is more fully utilized with trapezoidal flux density in air-gap. Based on the proper pole/slot number, it can effectively reduce commutation torque ripple. The commutation circuit should be properly controlled which is the key of the machine. This paper presents a load commutation method for CWBLDC machine, which relies on the EMF of its load (the motor) to reverse the phase current direction. Power devices of the commutation circuit can be turned off with no current flowing through, which can be considered as a form of soft switching. The analytical method of the machine which considers commutation process is derived and critical conditions for successful commutations are highlighted. Field-circuit coupled analysis and experiment results have been performed to verify the load commutation method.
