Abstract
PURPOSE:To eliminate positional shift between a processed magnetic flux axis and an actual magnetic flux axis, by changing the actual value or the command value of torque current and magnetic flux according to the saturation or non- saturation of a torque current regulator and an exciting current reguator. CONSTITUTION:A change-over switch 17A is changed by signal(a) showing whether or not a torque current regulator 13 is saturated, and to a slip frequency processing unit 11, a torque current command value iT' or actual value iT is applied. In other words, when the regulator 13 is non-saturated, then by the signal(a), the torque current command value iT' is selected as the input of the slip frequency processing unit 11 with the change-over switch 17A, and when the regulator 13 is saturated, then by the signal(a), the torque current actual value iT is selected as the input of the slip frequency processing unit 11 with the change-over switch 17A.
