PURPOSE:To smoothly operate an induction motor without causing stall phenomena. CONSTITUTION:In the case of controlling the stall of an induction motor through an inverter, it is so arranged as not to cause inconvenience such as start delay, acceleration impossibility, etc., by effectuating the output from a current limiting circuit 7 and performing the limitation of a load current only when it is judged to be in fixed output area with a comparator 3, thus smooth operation is materialized. |
