The utility model provides a high?power?density rotor structure, include rotor shaft, rotor yoke, fan -shaped big magnet steel and fill little magnet steel, fan -shaped big magnet steel adhesive fixation fills little magnet steel and inserts in the vacant air gap of adjacent fan -shaped big magnet steel on rotor yoke to the direction that magnetizes of filling little magnet steel adopts the parallel to magnetize, high?power?density rotor structure place motor magnetic loop is the fan -shaped big magnet steel S of fan -shaped big magnet steel N utmost point -> air -gap -> stator tooth -> stator yoke -> stator tooth -> air -gap -> utmost point -> and fills the fan -shaped big magnet steel N of the little magnet steel -> utmost point. The utility model discloses utilizing the space between the magnet steel and changing the direction that magnetizes of inserting the magnet steel, improve the magnetic gesture of motor on the one hand, load under the unchangeable condition at the structure and the electricity of mo
