ELEVATOR MOTOR CONTROL SYSTEM FOR A.C. INDUCTION MOTOR Abstract: An alternating current induction motor control system suitable to employ the motor as a hoisting motor for an elevator. The motor includes a high speed winding and a low speed winding, the high speed winding being used for acceleration and the low speed winding for deceleration. The low speed winding is connected in such a way as to rotate the motor in a direction opposite to that in which the high speed winding rotated it. A motion detector is provided to prevent the elevator from moving in the opposite direction after being brought to a stop at a landing. -1-
