Abstract: PURPOSE:To prevent transient phenomena in switching a control system by performing the control over an AC induction motor in a high speed region and in a medium and low speed region on the rotating speed set out from a reference value in switching respectively over to a synchronous system and an asynchronous system. CONSTITUTION:The rotating speed of an AC induction motor 1 is detected by a detection means 2 such as a pulse generator, etc. When this detected rotating speed exceeds a reference value, a programmable interval timer 112 outputs synchronizing signal pulse.
