Abstract

본 발명은 무정류자 직류 전동기를 정속도로 제어할 수 있도록 회전속도를 검출하는 무정류자 직류 전동기의 회전속도신호 검출장치에 관한 것으로 종래의 회전속도신호 검출장치는 신호검출용 패턴(12)을 구형으로 되고, 전체적으로는 환상형을 이루도록 인쇄회로기판(13)에 속도 검출용 자석(23)이 자력선이 인쇄회로기판(13)의 전면에 분포되게 되고, 이로 인하여 속도검출용 자석(23)의 자력선에 의해 신호검출용 패턴(12)에 유기되는 기전력이 낮아 회전속도신호의 레벨이 낮아지게 되므로 무정류자 직류 전동기를 정속도로 제어하는데 많은 지장을 주었다.The present invention relates to a rotation speed signal detection device of a non-commutator DC motor for detecting the rotation speed so that the non-commutator DC motor can be controlled at a constant speed. The magnetic force lines are distributed on the front surface of the printed circuit board 13 so that the speed detecting magnet 23 is distributed on the printed circuit board 13 so as to form an annular shape as a whole. As a result, the electromotive force induced in the signal detection pattern 12 is lowered, so that the level of the rotational speed signal is lowered.

본 발명은 속도 검출용 자석의 자력선이 신호검출용 패턴으로 집중되게 하여 회전속도신호의 레벨을 향상시킴으로써 무정류자 직류 전동기를 정속도로 정확히 제어할수 있다.According to the present invention, the magnetic force lines of the speed detecting magnet are concentrated in the signal detection pattern to improve the level of the rotation speed signal, thereby accurately controlling the non-commutator DC motor at a constant speed.
