Abstract
A reciprocating engine type electric generator includes means for recognizing a phase difference between a phase of an alternate voltage wave generated at a stator coil following rotation of a rotor and a phase of a reference alternate voltage, and means for controlling a speed of a rotational magnetic field generated at the stator coil by controlling the alternate voltage applied to the stator coil based upon the phase difference recognized by the means for recognizing the phase difference.
