PURPOSE:To provide a method for controlling an induction motor with stability in current control by using a simple circuital set-up. CONSTITUTION:In a vector control method, the torque current and magnetic flux current of a primary current of an induction motor are separately controlled. In an induction motor 1, two windings (U1, V1 and W1) and (U2, V2 and W2) are used, and the same phase current is provided to each winding through an individual control circuit 110 or 120. |
