Abstract

The utility model relates to an energy-saving motor with a thermal conduction function. Heat transfer oil is adopted a conduction device. A stator heat conduction housing (1) is provided with a plurality of hollow heat radiation chambers, and internal heat is conducted by the hollow heat radiation chambers to an external radiator via the heat transfer oil for heat radiation. An automatic or a forced heat radiation method is selected based on the motor, so that the heat radiation flywheel fan of the motor is avoided and a wind-guiding housing is avoided. The conventional heat radiation rib ventilation channels of the housing are replaced by the hollow heat radiation chambers, thereby improving the thermal conduction efficiency, effectively solving a big problem of heat radiation of the motor for a long period of time, and prolonging the running life of the motor. The energy-saving motor with a thermal conduction function is especially suitable for oil field motors under a high, low temperature and severe environment with exposure to the hot sun, for various generating sets with low noise, and for heat radiation systems of motors with a high rotating speed.
