Abstract

본 발명은 브이.씨.알의 드럼모터 구동 장치에 관한 것으로, 드럼모터(300)를 구동하기 위한 구동 전류를 공급하는 전류 공급부(100)와, 전류 공급부(100)로부터 발생하는 초기 구동 전류를 제어하며, 드럼모터(300)를 정속 구동을 제어하기 위한 제어 신호를 발생하는 마이컴(400)과, 마이컴(400)의 제어에 따라드럼모터(200)를 구동하기 위한 구동 전류를 드럼모터(300)로 제공하는 구동회로부(200)를 포함하고 구성된다.The present invention relates to a drum motor driving apparatus of V. C. R, and includes a current supply unit 100 for supplying a driving current for driving the drum motor 300 and an initial driving current generated from the current supply unit 100. And a drive current for controlling the drum motor 300 to generate a control signal for controlling the constant speed drive, and a driving current for driving the drum motor 200 under the control of the microcomputer 400. It includes and comprises a driving circuit unit 200 to provide.

따라서, 본 발명은, 스위칭 홀소자를 제거하고도 드럼모터의 구동을 제거할 수 있기 때문에 제드럼모터의 제작단가를 감소시킬 수 있는 장점이 있다.Therefore, the present invention has the advantage that the manufacturing cost of the drum motor can be reduced because the drive of the drum motor can be removed even if the switching hall element is removed.
