Description

편평형 브러시리스 직류모우터의 회전자Rotor of flat brushless DC motor

본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음Since this is an open matter, no full text was included.

제1도는 종래의 편평형 브러시리스 직류모우터에 따른 회전자의 단면을 도시해 놓은 도면.1 is a cross-sectional view of a rotor according to a conventional flat brushless DC motor.

제2도는 편평형 브러시리스 직류모우터의 공극내에서 형성하는 자속밀도상태를 도시해 놓은 도면.2 is a diagram showing a magnetic flux density state formed in the air gap of a flat brushless DC motor.

제3도는 본 발명에 따른 편평형 브러시리스 직류모우터의 회전자를 일부절개해 놓은 도면.3 is a view partially cut the rotor of the flat brushless DC motor according to the present invention.
