Abstract

본 발명은 모터 구동 제어 회로에 관한 것으로, 종래에는 모터 제동시 릴레이에 과전류가 인가되어 접점이 융착되거나 소손되는 문제점이 있고 하네스 타입으로 배선하므로 복잡한 결선에 의해 오결선이 발생하는 문제점이 있다. 이러한 종래의 문제점을 개선하기 위하여 본 발명은 모터 제동시 다이오드를 사용하여 페루프를 형성하여 릴레이접점의 사용을 방지함으로써 릴레이의 파손 및 접점 융착을 방지하고 인쇄 회로 기판(PCB)에 릴레이를 부착함으로써 결선을 간략화하여 오결선을 감소시킬 수 있도록 창안한 것이다.The present invention relates to a motor drive control circuit. Conventionally, there is a problem that an overcurrent is applied to a relay when a motor is braked, and a contact is fused or burned, and a wire is wired by a harness type. In order to solve such a conventional problem, the present invention uses a diode to prevent the use of a relay contact by using a diode during a motor braking, thereby preventing breakage of the relay and contact fusion, and attaching a relay to a printed circuit board It is designed to simplify wiring and reduce mis-wiring.
