<p><P>PROBLEM TO BE SOLVED: To provide a portable generator equipped with a protector which can protect a stator winding and a rotor winding of the generator from combustion losses by a simple constitution. <P>SOLUTION: The protector 31 comprises: a stator winding temperature detection means 33 which detects a temperature of the stator winding 30 of the synchronous generator 12; a revolution number detection means 34 which detects the number of revolutions; a time count means 35 which measures a duration when a low-revolution operation is detected; and an engine control means 36 which stops an engine when a detection temperature of the stator winding temperature detection means exceeds an upper limit value of a stator temperature which is set in advance, or when the duration measured by the time count means passes an allowable time which is set in advance. <P>COPYRIGHT: (C)2008,JPO&INPIT</p> |
