Abstract: Provided is an air conditioning system comprised of a plurality of indoor units connected to each other in parallel, each having an expansion valve, and an outdoor unit including a plurality of compressors, in which at least one of the compressors provided to the outdoor unit is a capacity modulation compressor including an electromotive driving unit for driving a plurality of compression units capable of selectively compressing a working fluid, and the electromotive driving unit for the capacity modulation compressor has a stator with a coil wound around thereon and a rotor rotating inside the stator, the rotor being an LSPRM including a rotor core, flux barriers, permanent magnets and conductive bars.

Abstract: The present invention provides a motor, comprising: a stator including a coil wiring portion to which power is supplied; a rotor, which includes conductive bars, flux barriers, and permanent magnets, and rotates through an interactive electromagnetic force between the conductive bars, flux barriers, and permanent magnets and the coil wiring portion of the stator; an integrated capacitor, which is electrically connected to the coil wiring portion and includes two capacitors connected to each other in parallel, an electrical switch serially connected to one of the two capacitors, and a casing on which the two capacitors and the electrical switch are securely mounted.

Abstract: Provided is a capacity modulation compressor, comprising: a shell forming a sealed interior space; a compression mechanism, which is positioned inside the shell and modulates a capacity for compressing a working fluid; and an electromotive driving unit, which is positioned inside the shell, includes a stator and a rotor, and drives the compression mechanism; and a shaft for transferring a torque of the electromotive unit to the compression mechanism, the rotor including a rotor core, conductive bars, flux barriers, and permanent magnets, starting running by an induction torque produced due to the presence of the conductive bars, and operating at a synchronous speed by a reluctance torque produced due to the presence of the flux barriers and a magnetic torque produced to the permanent magnets, and the compressing capacity for the compression mechanism to compress the working fluid being set lower than a maximum compression capacity.
