Abstract: This rotor for a rotating electric motor includes a hollow cylindrical rotor core with a plurality of laminated electromagnetic steel plates. The inner and outer circumferential surfaces of the rotor core each face a magnetic gap. The rotor core is interposed between a first rotating support member and a second rotating support member. A flange is formed on a first end of a tubular pin protruding from a first hole of the first rotating support member. A tubular expansion part of the tubular pin plastically deforms due to fluid pressure so as to come into close contact with a through hole of the rotor core, the first hole of the first rotating support member, and a second hole of the second rotating support member.

The glass tube includes an end portion having an end surface. The thermal-expansion-difference absorption portion is formed from metal, and includes a connecting end connected to the end portion of the glass tube.

Abstract: When sub-field magnets 8a and 8b are not provided, the magnetic fluxes that pass through main field magnets 7a and 7b respectively and interlink with stator windings 5 and first rotor windings 6, and the magnetic fluxes that pass through the main field magnets 7a and 7b respectively and short-circuit adjacent main field magnets 7b? and 7a? are generated. The short-circuited magnetic fluxes do not contribute to torque generation, therefore a favorable inner periphery magnetic circuit is not formed, and the torque received between a second rotor 4 and a first rotor 3 becomes small. When sub-field magnets 8a and 8b are provided, on the other hand, the short-circuited magnet fluxes interlink with the first rotor windings 6 by the sub-field magnets 8a and 8b, and an inner periphery magnetic circuit is formed, whereby the motor driving torque received between the second rotor 4 and the first rotor 3 increases.

The compressor is selectively driven by an engine and an electric motor. The calculator calculates a thermal load based on the detected information. The controller compares the thermal load with a predetermined value. The controller changes displacement of the compressor to a first predetermined displacement value and selects the engine as a drive source of the compressor when the thermal load is larger than the predetermined value. The controller changes the displacement of the compressor to a second predetermined displacement value that is smaller than the first predetermined displacement value and selects the electric motor as the drive source of the compressor when the thermal load is equal to, or smaller than the predetermined value.
