Abstract

PURPOSE: To perform a smooth starting by decreasing a field system current of the synchronous motor, increasing the armature current when started, increasing the field system current as a rotational speed is increased and decreasing the armature current to restrict the electric current flowing to a power transformer and to perform a smooth starting.
