Abstract

본 발명은 직류서보 전동기의 구동회로에 있어서, 전동기로 정격전류이상의 높은 구동전류가 지속적으로 공급되는 것을 방지할 수 있도록 된 직류서보 전동기의 과부하 보호회로에 관한 것으로, 전동기로 공급되는 전류치를 검출하는 전류량 검출수단과, 상기 전류량 검출수단에 의한 검출전류치를 시간적으로 적분하는 제어수단 및 상기 적분수단에 의한 적분량을 전동기의 듀티사이클에 따른 기준 전력량과 비교하는 비교수단을 포함하여, 상기 비교 수단에 의한 비교결과를 근거로 전동기의 구동을 제어하도록 구성된 것을 특징으로 한다.The present invention relates to an overload protection circuit of a DC servo motor, which is capable of preventing the motor from continuously supplying a high drive current higher than the rated current in the drive circuit of the DC servo motor, and detecting a current value supplied to the motor. A current amount detecting means, control means for integrating the detected current value by the current amount detecting means in time, and comparing means for comparing the integral amount by the integrating means with a reference power amount according to the duty cycle of the electric motor. It characterized in that it is configured to control the driving of the motor based on the comparison result.
