Publication number: 20240162773Abstract: An electric motor disclosed herein may comprise a rotor core fixed to a shaft, a stator, and first and second refrigerant passages. The stator may include coil ends at both ends. The first refrigerant passage may be provided in the shaft and arranged outside the rotor core in an axial direction of the shaft. The second refrigerant passage may extend inside the rotor core. A first outlet of the first refrigerant passage may be provided on the shaft, and an ejecting direction of refrigerant at the first outlet may be directed towards one of the coil ends. The rotor core is cooled by the refrigerant flowing in the second refrigerant passage. The coil ends are cooled by the refrigerant flowing in the first refrigerant passage, that is, the refrigerant that has not cooled the rotor.Type: ApplicationFiled: November 13, 2023Publication date: May 16, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Kei OHTA, Hideaki MIYAZONO, Junya KOBAYASHI, Junichi DEGUCHI, Hironori ASAOKA, Sho OKAZAKI

Publication number: 20240162766Abstract: An electric motor disclosed herein may include a stator, a supply hole, a first flow passage, and second flow passages. The first flow passage and the second flow passages may be provided in the stator. The first flow passage may extend along a circumferential direction of the stator. The second flow passages may extend along an axis of the stator and cross the first flow passage. A plurality of guides may be provided in the first flow passage to disturb a flow of refrigerant. The refrigerant is supplied from the supply hole to the first flow passage and disturbed by the guides. A part of the refrigerant of which flow is disturbed flows into the second flow passages. The refrigerant is distributed, thus, the refrigerant flows evenly into the second flow passages. The entire stator is thus effectively cooled.Type: ApplicationFiled: November 8, 2023Publication date: May 16, 2024Applicant: TOYOTA JIDOSHA KABUSHIKI KAISHAInventors: Hideaki MIYAZONO, Junichi DEGUCHI, Hironori ASAOKA, Kei OHTA, Sho OKAZAKI, Junya KOBAYASHI
