The Development of the Encoder for 7 phases 6 poles BLOC Motor of High Speed

고속 7상 6극 브러시레스 직류전동기 전용 엔코더 개발

In general, to get the accurate switching point of power electronic components is dependent on a given rotor position by the encoder. However, a conventional encoder may not be used to detect position and speed of the developed motor due to the very high speed. Thus, an encoder that uses the hall effect directly was designed and applied. This paper presents the developed encoder that meet requirement of military purpose. To confirm the developed encoder, the experimental results are shown.
