A rotor that includes a shaft; a rotor core that is attached to the shaft and that is configured of a plurality of electric steel plates that are stacked; and a permanent magnet that is embedded in the rotor core, wherein: a coolant supply port that supplies a coolant to the rotor core is provided in the shaft, and at least two electric steel plates of the plurality of electric steel plates each include a first portion that has a first thickness in a rotational axis direction and a second portion that has a second thickness in the rotational axis direction, which is thinner than the first portion, the second portion extending in a radial direction and configuring a flow path through which the coolant supplied from the coolant supply port of the shaft flows.

Rotor

In a vertical through hole of a rotational shaft, a first protrusion portion and a second protrusion portion protruding from an inner peripheral surface of the vertical through hole are provided in an axial direction of the through hole to form a storage area for storing oil, and discharge holes for directly discharging oil flowing over the first protrusion portion into the transaxle casing are provided in parallel with cooling holes.

Cooling system for motor

A rotating electrical machine includes a rotor which has a rotor core formed by stacking magnetic plates having an annular plate shape in an axial direction, a permanent magnet is inserted into a magnet insertion hole formed in the rotor core, and a rotor shaft is inserted into a shaft insertion hole surrounded by an inner peripheral surface of the rotor core; and a stator. A radial communication passage is formed by a communication penetration hole group that is formed by sequentially communicating a plurality of the penetration holes from a shaft insertion hole to a magnetic resistance hole in the radial direction. The plurality of the penetration holes are divided into at least two specific magnetic plates and formed such that the radial positions of the penetration holes are different from each other and the penetration holes partially overlap each other when viewed in the axial direction.

A stator that includes a cylindrical stator core, which has a plurality of slots that are provided at predetermined intervals in a circumferential direction and open toward an inner peripheral surface of the stator core; and a coil, which has a coil end portion protruding from an axial end of the stator core.

Stator

First and second connection mechanisms electrically connect power cables extending in the same direction to first and second electric motor neighboring to each other in the extending direction of the power cables, respectively. The first connection mechanism of the first electric motor is arranged in a radially outer portion, and the second connection mechanism of the second electric motor is arranged in a space between the electric motors. Since both the connection mechanisms are located on the opposite sides of a joint surface between the first and second casings accommodating the first and second motors, respectively, the first and second connection mechanisms can be components on the first and second casing sides, respectively. This structure can prevent increase in size in a rotation axis direction, and can improve assembly workability for the motors.

Motor module

A motor driving device manufacturing method for manufacturing a motor driving device including a motor case, a rotor, and a stator disposed concentrically with the rotor on the outer periphery of the rotor, includes a measuring step for measuring a position of the stator relative to an axial center of the rotor from an inner side of the stator using a measuring device inserted in the stator; an adjusting step for adjusting the position of the stator from the inner side of the stator based on a measurement result of the measuring step using an adjustment device inserted in the stator, wherein the measuring step and the adjusting step are executed in a rotor not-inserted state, in which the stator is housed in the motor case and the rotor is not inserted in the stator; a stator fixing step for fixing the stator in the motor case; and a rotor shaft-support step for inserting the rotor in the stator and shaft-supporting the rotor on the motor case.

The shield shell is formed of a shield shell main body, a shield shell auxiliary member and a fixing member. The shield shell main body is made of die-cast aluminum. The shield shell auxiliary member is formed by pressing a steel plate, and has a surface plated with gold. The fixing member has a ring shape, which is formed by pressing a steel plate. With this configuration, it is possible to provide a shield shell that can be manufactured at a low cost, that can improve reliability of the shielding effect, and that can improve assembling workability of the shielded wire.

Shield shell

A cable for supplying electric power to a motor is electrically connected to an inner conductor of a terminal block via a contact by a mating structure of a male connector and a female connector. A connecting member for electrically connecting the inner conductor and a motor winding includes a fixed terminal and a movable terminal. The fixed terminal is electrically connected to the inner conductor by a fixing member and has a portion formed to extend along a terminal at the tip of the motor winding. The movable terminal is elastically deformable in accordance with the position of the terminal and arranged to hold the terminal interposed between itself and the fixed terminal. As a result, a motor module can be assembled to the terminal block integrally formed with a housing, while component tolerance is effectively absorbed by the connecting member.

A connector connection structure includes: a female connector on a housing accommodating a dynamo-electric machine mounted in a vehicle; and a male connector shaped so as to be fitted into the female connector by inserting it with a force not smaller than a predetermined amount. The male connector includes a contact joinable with a contact of the female connector to be electrically connected, and a rod-like lever connected with the male connector via a fulcrum. The lever generates the force not smaller than a predetermined amount by applying, with its one end's position being restricted, a rotation force to the other end. The housing includes a protrusion for restricting the position of the one end.

Connector connection structure

A male connector to be connected to a female connector provided at a housing accommodating a vehicle-mounted electrical device includes a contact point to be connected to a contact of the female connector, a cable connected to the contact point, and a shield shell covering the contact point. A fixing structure for the male connector includes a bolt for fixing the shield shell to the housing, on the contact point side, and a clamp for fixing the cable to the housing, on the cable side. The fixed state of the cable established by the clamp is such a state as to allow for more movement of an object to be fixed than does the fixed state of the shield shell established by the bolt.

Connector fixing structure

A vehicle-connector routing structure is provided with which routing can be made through a narrow space. The vehicle-connector routing structure includes a chassis having an engine compartment and a tunnel continuing from the engine compartment, motors provided in the tunnel, and vehicle connectors connected to the motors. The vehicle connectors include bus bars extending at least from the motors to the engine compartment through the tunnel. One bus bar extends to an inverter. The other bus bar is connected to a flexible electric wire.
