Rotary electric machine system and hybrid power system having same

The invention provides a rotating electric machine system and a hybrid power system having the same. A rotating electrical machine system (10) has a rotor (34) having a permanent magnet (72) and a rotating shaft (40). The rotating shaft is supported by the rotating motor housing (14) through a first bearing (74) and a second bearing (84). A first oil supply passage for supplying lubricating oil to the first bearing and the second bearing is formed in the rotating electric machine housing. In addition, an inner rotor oil passage (354) is formed inside the rotor. A portion of the lubricating oil is shunted from the first oil supply passage and supplied to the rotor inner oil passage. 本发明提供一种旋转电机系统和具有该旋转电机系统的复合动力系统。旋转电机系统(10)具有转子(34)，转子(34)具有永久磁铁(72)和旋转轴(40)。旋转轴通过第1轴承(74)和第2轴承(84)被支承于旋转电机外壳(14)。在旋转电机外壳形成有第1供油道，第1供油道用于向第1轴承和第2轴承供给润滑油。另外，在转子的内部形成转子内油道(354)。润滑油的一部分从第1供油道分流，供给到转子内油道。
