Abstract
본 발명은 삼상 모터 제어 장치에 관한 것으로, 삼상 모터의 '온', 또는 '오프' 신호를 발생하는 신호 입력부(10)와, 삼상 모터의 최적 구동을 위한 사전 결정된 제어 신호 패턴을 저장하는 메모리(30)와, 신호 입력부(10)로부터 '온' 신호가 입력되면 메모리(30)에 저장된 제어 신호 패턴을 판독하여 삼상 모터의 구동을 제어하기 위한 제어 신호를 발생하는 마이컴(20)과, 마이컴(20)의 제어 신호에 따른 구형파신호를 발생하는 구형파 발생기(40)와, 구형파 발생기(40)로부터 제공되는 구형파 신호에 다랄 삼상 모터를 구동하는 모터 구동부(50)를 포함하고, 구성되어 삼상 모터의 각 단자에 일정 주기를 가진 구형파 신호를 소정의 시간 지연을 두고 연속적으로 인가하여 그 구동 속도를 제어하기 때문에 기계적인 소음을 없애주고 모터의 구동속도도 항상 일정하게 유지하여 최적의 상태로 삼상 모터를 구동할 수 잇는 장점이 있다.The present invention relates to a three-phase motor control apparatus, comprising a signal input unit (10) for generating an 'on' or 'off' signal of a three-phase motor, and a memory for storing a predetermined control signal pattern for optimal driving of the three-phase motor ( 30 and the microcomputer 20 that reads a control signal pattern stored in the memory 30 and generates a control signal for controlling the driving of the three-phase motor when the 'on' signal is input from the signal input unit 10, and the microcomputer ( A square wave generator 40 for generating a square wave signal according to the control signal of FIG. Since the square wave signal with a certain period is continuously applied to each terminal with a predetermined time delay to control the driving speed, mechanical noise is eliminated and the driving speed of the motor is always constant. The advantage is that it can maintain and drive a three-phase motor in an optimal state.
