摘要： The invention provides a permanent magnet motor capable of preventing the productivity from being reduced and appropriately fixing the permanent magnet simultaneously, and reducing the vibration and noise and achieving high efficiency. The permanent magnet motor comprises a rotor having a laminated iron core (3) in the rotating shaft direction with a plurality of grooves (4) along the rotating direction and a stator for providing the rotating field for the rotor, wherein, the grooves are laminated with a plurality of flat magnets (5) in the length direction, the permanent magnet motor comprises a rotor end plate (1) arranges at one end in the rotating shaft direction of the laminated iron core (3) for covering an opening part at one side of the grooves (4), a rotor end plate (2) arranged at another end at opposite side of the rotor end plate (1) for covering another opening part at the other side of the groove (4), and a press part (6) for pressing the magnet (5) to the rotor end plate (2) from the inner of the projection in the rotating shaft direction of the groove (4) of the rotor end plate (1).

摘要： PROBLEM TO BE SOLVED: To provide a gas heat pump air conditioner capable of properly operating a gas engine even under variation of air conditioning load, and saving energy while continuing a stable operation. SOLUTION: The gas engine 2 and an electric motor 3 are used in driving a compressor 1 for a gas heat pump. A system control portion 5 comprises a means for setting driving force by the gas engine 2 for the driving force requested by the compressor 1, and calculating an operation cost in operating the gas engine 2 by the set driving force, a means for setting the driving force by the electric motor 3 for the driving force requested by the compressor 1, and calculating an operation cost in operating the electric motor 3 by the set driving force, and a control means for independently controlling the driving force of the gas engine 2 and the driving force of the electric motor 3, and changing a ratio of the driving force set in the gas engine 2 and the driving force set in the electric motor 3, and the ratio is changed to minimize the sum of the operation costs of the gas engine 2 and the electric motor 3.
