MOTOR COIL COOLING STRUCTURE

A motor coil cooling structure, includes: a rotor core fixed to a rotation shaft having an internal supply path for coolant, and that includes a rotor-side flow path in communication with the supply path and passing through to a radial direction outer side of the rotor core; a stator core disposed at the rotor core so as to form a space between the stator core and the rotor core, and that includes slots each housing a coil; first flow paths formed so as to include the slots and pass through the stator core in a radial direction; second flow paths formed in an upper portion of the stator core relative to the rotation shaft, including the slots, extending in a radial direction and passing through the stator core only at a radial direction outer circumferential side thereof; and a supply section that supplies coolant from above the stator core.
