Abstract:This paper introduces vector control of six-phase PMSMs with selective harmonic elimination PWM (SHEPWM) technology. Mathematic model of six-phase PMSM is given. Then relation between harmonic currents and voltages is derived. Harmonic current responses of salient pole six-phase PMSMs and non-salient pole six-phase PMSMs are different by applying the same harmonic voltage excitation. Besides, the method of smooth transition between different SHEPWMs is given. Some experiments which based on vector control of s… Show more
scite is a Brooklyn-based startup that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
