  • Patent number: 9954419
    Abstract: A mist is generated by scooping up cooling oil using a lower end portion of a non-load side end plate. Air containing this mist is circulated by a centrifugal fan provided to a load side end plate to form a recirculating air current flowing through first through-holes in a rotor core and through a ventilation passage on the outside of a rotor in opposite directions. According to a cooling mechanism as above, a mist generated in at least one point in the housing can be supplied with the recirculating air current to every point across a whole area within the machine. Hence, both of the rotor and a stator can be cooled efficiently with a small amount of mist.

  • Patent number: 9882444
    Abstract: A terminal block is fixed to a frame holding a stator and in phase with the stator whereas a part of an outside wire is fixed to a case. Hence, a bus bar extracted from a connection plate is welded to the terminal block hardly under the influence of a tolerance caused by integration of components and a tolerance of assembly. Even when a load applied from the outside gives rise to a phase difference between the case and the frame, a tolerance can be absorbed by the outside wire. Accordingly, a load applied to a weld portion of the terminal block and the bus bar can be reduced.
