Engine production units that use induction motors are sometimes needed to be using an ac motor can rotate forward and backward so that it takes a tool that can set the direction of rotation of induction motors, the picture above is a picture of a circuit that works to set the direction of rotation of the motor induction 3 phase, be it in the position of star / wye or delta position.
at the present time the conventional regulator circuit above is still widely used by the industry, both small and large industrial industries. Specifically, its use is not very important, because the production machines had been developed in terms of the use and construction of the engine itself. But in principal is the same, namely the flipping reverse the direction of rotation of induction motors.
