More Information
Summary:A control unit for an induction motor which detects a primary current in an induction motor, obtains an error current which becomes zero when an actual value of the primary magnetic flux coincides with a set value provided as a product of I1d* and a primary self inductance L1, executes correction of the primary resistance, primary self-inductance, and leak factor according to the error current. Furthermore, the control unit has a correcting section control circuit in which a set error most influential for effecting coincidence between the primary magnetic flux in the induction motor with the primary magnetic flux is preferentially corrected.
