| 发明名称 | Generator motor cooling structure and generator motor | ||
| 摘要 | A generator motor cooling structure for cooling a generator motor, which includes a housing storing an input/output shaft to which a rotor is attached and a stator disposed at an outer periphery portion of the rotor, by a cooling medium, includes: a protrusion portion that protrudes toward a coil of the stator from an inner surface of the housing of one end side in a direction of a central rotation axis of the input/output shaft to form a passage of the cooling medium between the coil and the protrusion portion, and is disposed around the central rotation axis. | ||

| 主权项 | 1. A generator motor cooling structure for cooling a generator motor, which includes a housing storing an input/output shaft to which a rotor is attached and a stator disposed at an outer periphery portion of the rotor, by a cooling medium, comprising: a protrusion portion that protrudes toward a coil of the stator from an inner surface of the housing of one end side in a direction of a central rotation axis of the input/output shaft to face a side portion of a coil end of the coil and form a passage of the cooling medium between the coil and the protrusion portion, and is disposed around the central rotation axis, wherein the rotor rotates together with the input/output shaft, and ejects the cooling medium supplied from a radial inside toward a radial outside by a centrifugal force. | ||
