Pseudo vector control – an alternative approach for brushless DC motor drives
... techniques Torque ripple is the main concern of the BLDCM because it limits this kind of motor from many applications. There are three main sources of torque production (and therefore of the torque ... ripple) in BLDCMs: cogging torque, reluctance torque, and mutual torque [1]. The torque ripple can be reduced by (a) motor design; (b) control means; (c) or both o...
