Abstract

본 발명은 모터를, 많은 전류를 공급하는 1분 운전 영역으로 구동시킬 경우에 모터가 손상되지 않도록 보호하는 것이다. 본 발명은 최대의 토르크를 발생하게 하는 1분 운전 영역으로 모터가 계속 구동되어 손상되는 것을 미연에 방지하는 것으로서 미리 소정의 시간을 설정하여 두고, 제어부는 인버터가 모터로 공급하는 전류의 레벨로 모터가 최개의 토르크를 발생하는 1분 운전 영역으로 구동시키는 지를 판단하며, 1분 운전 영역으로 모터를 구동시킬 경우에 시간을 카운트하며, 미리 설정된 시간이상 1분 운전 영역으로 계속 구동시킬 경우에 인버터를 제어하여 모터로 공급하는 전류를 감소시키게 한다.The present invention protects the motor from being damaged when the motor is driven to the one minute driving region which supplies a large amount of current. The present invention prevents the motor from being continuously driven and damaged in a one minute operation region that generates the maximum torque, and sets a predetermined time in advance, and the control unit sets the motor to the level of current supplied from the inverter to the motor. Determines whether to drive to the one minute operating area that generates the maximum torque, counts the time when the motor is driven to the one minute operating area, and operates the inverter when the drive continues to the one minute operating area for more than the preset time. Control to reduce the current to the motor.
