Abstract

인버터(1)가 고장을 일으켜도 폭주하지 않고 또 브레이크의 응답성이 우수하고, 정지시에 짐이 낙하해서 쇼크를 발생하는 일이없는 가변속 권상기를 얻는다. 인버터(1)로부터 권상모터(2)에의 출력은, 다이오드 브리지 정류회로(13)과 브레이크 코일(3)로 되는 브레이크 회로를 직렬로 삽입한다. 또 브레이크 회로와 병렬로 전자릴레이 코일(8), 상개접점(8a), 전자릴레이코일(9)에 의해 구동되는 로크 소실과 동시에 권상모터(2)를 확실하게 "록"할 수가 있다.Even if the inverter 1 fails, a variable speed hoist is obtained which is not congested and excellent in the responsiveness of the brake, and does not cause shock when the load is dropped at the stop. The output from the inverter 1 to the hoisting motor 2 inserts the diode bridge rectifier circuit 13 and the brake circuit which becomes the brake coil 3 in series. In addition, the hoisting motor 2 can be reliably " locked " simultaneously with the lock loss driven by the electromagnetic relay coil 8, the top contact 8a, and the electromagnetic relay coil 9 in parallel with the brake circuit.
