摘要： A motor cooling device having good cooling performance, which is adapted to promote heat transfer between a coil end and a coil end cover even if the flowing amount of oil is small. A heat of a stator is withdrawn by the oil flowing around the coil end. For this purpose, the motor cooling device comprises a flow path formed between an outer face of the coil end and an inner face of the coil end cover, and a flow rate adjusting unit for changing a cross-sectional area of the flow path by moving the coil end cover toward the coil end or away from the coil end. The flow rate adjusting unit widens the cross-sectional area of the flow path in case a feeding amount of the oil to the flow path is relatively large, and narrows the cross-sectional area of the flow path in case a feeding amount of the oil to the flow path is relatively small.

摘要： A liquid-cooled stator and rotor assembly for use as an electric motor or generator includes a housing having a first end bell, a second end bell, and at least one fluid orifice in the first end bell. A stator is fixed within a stator cavity of the housing. The stator includes a stator core and a plurality of windings for conducting a flow of electricity. A rotor for magnetically interacting with the stator is also included, the rotor being rotatably mounted between the first end bell and the second end bell within a rotor cavity. A first sealing ring and a second sealing ring are provided to form a fluid seal against the respective end bells and against a portion of the stator such that a cooling fluid entering the stator cavity via the orifice does not enter the rotor cavity.

The oil outlet holes (3) are located above the winding coils (6) and the oil-guides (4) are located between the oil outlet holes (3) and the winding coils (6). Oil entering from the oil inlet hole (7) pours onto the winding coils (6) by the guidance of the oil-guides (4) after flowing through the oil passage (2) and flowing out of the oil outlet holes (3). The winding coils of the electrical machine can be effectively cooled and the electrical machine can achieve higher thermal durability. An oil cooling method for the electrical machine is also provided.

摘要： An electric machine (100) comprises a stator (112) and a rotor (114a, b) mounted for rotation about a rotor axis (120) with respect to the stator. Permanent magnets (124a, b) are carried by the rotor. The rotor has an output (190). The stator has coils (122) wound on stator bars (116) for interaction with the magnets. The rotor has two stages (114a,b) arranged one at either end of the stator bars, with two air gaps (126a,b) between the ends of the bars and the rotor stages. An annular housing (102, 142a, b, 146) retains and mounts the stator. A bearing (164a, b) is between the rotor and stator, the rotor being hollow around said rotor axis. There are two significant magnetic flux paths (30,30′) of the motor. The first passes between adjacent coils in a circuit on a substantially circumferential plane with respect to the axis (120). A second path 30′ is in an axial plane, passing around the bearing. The stator coils are spaced around the rotor axis and approach the rotor axis no closer than a first, stator radius (R1) of the stator. The bearing comprises rolling elements rolling on a surface of the rotor that is no closer to the rotor axis than a second, rotor radius (r), which rotor radius is between 60% and 90% of the stator radius.
