Abstract: A compressor includes a closed container, a compression element placed within the closed container, and a motor placed within the closed container to drive the compression element via a shaft. An integral structural part is formed by integrally assembling a compression element with a rotor via a shaft. The natural frequency of the integral structural part is larger than five times the maximum number of rotations of the compressor during its operation. A coil of a stator is provided in concentrated winding. A cylindrical-shaped rotor core of the rotor has a small-diameter portion and a large-diameter portion provided inside the rotor core. The shaft is fixed to the small-diameter portion of the rotor core. A bearing of the compression element is arranged to support the shaft and is inserted into the large-diameter portion of the rotor core, with the shaft being cantilevered by the bearing.

Abstract: A high-pressure, dome-type compressor includes a DC motor 5 having a rotor 5a that uses a rare earth/iron/boron permanent magnet having an intrinsic coercive force of 1.7 MA.m−1 or greater in a rotor thereof and has a rated output or 1.9 kW or higher. The motor, which drives a compression element 3 in a casing 2, is disposed in a high pressure, high temperature area 6, which is filled with gas discharged from the compression element. An inverter 10 controls current supplied to the motor such that the motor temperature becomes equal to or less than a predetermined temperature and an opposing magnetic field generated in a stator has a predetermined strength or less. Since the magnet does not reach a high temperature and is not exposed to a strong opposing magnetic field, it is hardly demagnetized. As a result, performance of the motor and of the compressor is stable.

Abstract: There is provided a high-pressure dome type compressor which comprises a motor using a rare earth magnet and has stable performance. There are provided a compression element 3 and a DC motor 5 for driving the compression element 3 in a casing 2. The motor 5 is disposed in a high pressure area 6, which obtains a high temperature and high pressure due to a discharged gas. The motor 5 includes a rare earth/iron/boron permanent magnet having an intrinsic coercive force of 1.7 MA/m−1 or greater in a rotor and has a rated output or 1.9 kW or higher. An inverter 10 controls a current to be supplied to the motor 5 such that a temperature of the motor 5 becomes equal to a predetermined temperature or lower and that an opposing magnetic field generated in a stator of the motor 5 has a predetermined strength or less. Therefore, since the rare earth magnet of the motor 5 does not obtain a high temperature and is not exposed to a strong opposing magnetic field, the magnet is hardly demagnetized.
