SRM의 진동ㆍ소음의 저감을 위한 직류여자 전류방식에 관한 연구 = Study on the D.C Excitation Commutation Method of SRM for Reduction of Vibration/Acoustic Noise

다국어 초록 (Multilingual Abstract)

SRM drives generate large vibration and acoustic noise because it is commutated individually by step pulse m.m.f on each phase pole, The frequency or motor speed of peak vibrations and acoustic noises is coincided with the natural resonant frequency of the magnetic structure and frame material And this radial vibration force is induced on the phase commutation region. This paper suggest the new electromagnetic structure of SRM with auxiliary commutating winding excited d.c e m.f This phase- commutating winding is coupled magnetically between one phase winding and the other, In this commutation mechanism, the vibrating force is failed down, As a result, SRM with d.c exciting commutation winding is very useful to reduce vibration and acoustic noise of SRM drive,
