And a forward and reverse control device that is connected via a reactance element and allows the first winding to be connected through the first tap.

주권선으로 사용될 때의 권선수와 보조권선으로 사용될 때의 권선수를 다르게 할 수 있도록 탭을 설정함에 의해 정역회전시 제1, 제2권선과 탭과 콘덴서 사이의 전류경로를 달리하는 스위치 및 제어회로의 구성이 간단하게 되는 잇점을 갖는다.Switch and control to change the current path between the first and second windings and the tap and the capacitor during forward and reverse rotation by setting the tap so that the number of turns when used as the main winding and the number of turns when used as the auxiliary winding is different. This has the advantage of simplifying the circuit configuration.
