Abstract
When a motor/generator is changed over from a motor mode to a generator mode, field current is minimized. In the generator mode, idling is performed until the engine temperature attains a set temperature, after which the field current is supplied. As a result, load upon an engine is lightened immediately after the engine is started and the risk of the engine stalling is eliminated.
