1. An engine generator apparatus having a motor/generator operated in a motor mode for starting an engine and in a generator mode to be driven by the engine, comprising:

  • first control means for minimizing field current when a changeover is made from the motor mode to the generator mode;

    second control means operable in the generator mode for maintaining rotational speed of the engine at a first set rotational speed until engine temperature attains a set temperature, and for outputting a signal, which increases the rotational speed of the engine to a second set rotational speed, to throttle-adjusting means after the engine temperature attains said set temperature; and

    third control means for increasing the field current of the motor/generator from the minimum state after the engine temperature attains said set temperature.
