Zusammenfassung:PURPOSE:To enhance the heat removing efficiency without using a separate part like a jacket by forming a pair of brackets and a stator in a circulating passage of coolant and preventing the leakage from the passage in a laminated core by a metal coating layer. CONSTITUTION:A cooling circulating passage 27 connected with an inlet 23 and a coolant circulating passage 28 connected with an outlet 24 are formed in a bracket 13. Four circulating passages 29-32 which pass axially a stator 11 are formed in the stator 11. A metal coating layer 38 is fusion-bonded to the inner surfaces of the passages 29-32 in the laminated core 18 of the stator 11, thereby preventing the leakage from the passages 29-32.
