PURPOSE:To improve the motor cooling capacity by gushing out the insulated cooling liquid into the inside of a motor, cooling the motor and recooling the insulated cooling liquid exhausted from the motor and then circulating it. CONSTITUTION:The insulated cooling liquid composed of the carbon fluoride is sprayed out from an injection nozzle 8 for insulated cooling liquid to the winding terminal and cools the inside of a motor. The insulated cooling liquid is exhausted from an insulated cooling liquid exhaust slot 9 and cooled in a heat exchanger 10. Then the liquid is compressed by the application of high pressure and gushed out again into the inside of the motor through an injection nozzle 8. Thus, the cooling efficiency is improved.
