PROBLEM TO BE SOLVED: To achieve good heat radiation performance by using a heat radiation member sandwiched between a motor case and a stator coil in a rotary electric machine.SOLUTION: A rotary electric machine 10 includes: a stator 12 including a stator core 20 and a coil wound around the stator core 20; a rotor 14 disposed at the inner periphery side of the stator 12 and having a rotor rotary shaft 32; a motor case 16 which fixes the outer periphery side of the stator core 20 and rotatably supports the rotor rotary shaft 32; and a heat radiation member 40 sandwiched between an outer peripheral surface of a coil end 22 protruding in an axial direction of the stator core 20 and an inner wall surface 18 of the motor case 16. The heat radiation member 40 includes: an outer resin member 42 made of a material having high heat insulation quality and high oil resistance; and an inner resin member 44 made of a material having high heat conductivity and high elasticity. An entire outer peripheral surface of the inner resin member 44 is covered by the outer resin member 42.SELECTED DRAWING: Figure 1 |
