ROTARY ELECTRIC MACHINE, AND ELECTRIC VEHICLE EQUIPPED WITH THE SAME

摘要

PROBLEM TO BE SOLVED: To provide a rotary electric machine in which a pump and coolant paths for circulating liquid coolant are put together compactly and downsized and assemblability and maintainability are improved.SOLUTION: A rotary electric machine comprises: a rotor 5 having a rotary shaft 6; a stator core 1 arranged on an outer peripheral side of the rotor; an armature winding 4 wound to the stator core; a housing 8 which holds the stator core on its outer peripheral side; and brackets 7 which are arranged on both ends in a rotary shaft direction of the housing and hold a bearing of the rotary shaft; a pump 10 which circulates liquid coolant that cools the armature winding 4, the stator core 1 and the rotor 5; coolant paths 12 in which liquid coolant circulates; and a reservoir part 11 of liquid coolant. The pump 10 is arranged on an outer peripheral side or an end part side in a rotary shaft direction with respect to the bearing 9, the pump 10 and the coolant paths 12 are integrally provided with the brackets 7 together with the bearing 9, the pump 10 is freely detachable from the brackets 7, and the coolant paths 12 are freely exposed from the brackets 7.
