    摘要： A self-starting type permanent magnet synchronous motor comprises a stator and a rotor. The rotor comprises a rotor core having a plurality of slots provided in an outer periphery thereof and a cage winding comprising conductive bars embedded in the slots and conductive end rings that short-circuit the conductive bars on both end faces of the bars in an axial direction thereof. The rotor core comprises at least one magnet insertion hole arranged on an inner peripheral side from the slots, and at least one permanent magnet embedded in the at least one magnet insertion hole. When a pole center axis is denoted as a d-axis and an axis deviating from the pole center axis by an electrical angle 90° is denoted as a q-axis, a flux content generated by the cage winding during start-up becomes maximal in the vicinity of and on one of the d-axis and the q-axis.

    摘要： A second frame is arranged between a first frame and an orbiting scroll, and a central space and an outer peripheral space are sealed off by a seal portion, which is formed between an end surface of a shaft support of the orbiting scroll and the second frame. Also, a balance weight is arranged in a space between an underside of the second frame and the first frame. Thereby, most of an oil having lubricated respective shaft supports flows into the space below the second frame, and the oil accumulated in the space is discharged through an oil scavenge pipe into an oil reservoir in a lower portion of a closed vessel. Also, since the balance weight can be assembled from a side of the orbiting scroll in a state, in which the second frame is removed, it is possible to mount the balance weight close to the orbiting scroll.
