Abstract

본 발명은 브이.씨.알의 드럼모터 장치에 관한 것으로, 브이.씨.알의 녹화 및 재생용 헤드가 취부된 드럼을 구동하기 위한 고정자(50) 및 회전자(20)를 가진, 브이.씨.알의 드럼모터 장치에 있어서, 상기 회전자(20)가 1회전할 때마다 각각 6개의 스위칭 펄스를 발생하는, 상기 고정자(50)에 장착된 제1 및 제2스위칭 소자(18,12)와, 상기 제1스위칭 소자(18)에서 발생된 펄스를 수신하여 6개의 펄스가 수신되면 1개의 PG 펄스를 발생하는 마이컴(30)을 포함하고 구성되어, 2개의 홀소자중 1개의 홀소자를 제거하고 드럼모터를 구동하므로써 브이.씨.알의 제작 단가를 감소 시킬 수 있다.The present invention relates to a drum motor device of a V. C. egg, having a stator (50) and a rotor (20) for driving a drum on which a recording and reproducing head of the V.C. In the C.R drum motor apparatus, the first and second switching elements 18 and 12 mounted on the stator 50 generate six switching pulses each time the rotor 20 rotates one rotation. And a microcomputer 30 which receives one of the pulses generated by the first switching element 18 and generates one PG pulse when six pulses are received. By removing and driving the drum motor, the manufacturing cost of V.C. eggs can be reduced.
