Abstract

A thrust magnetic bearing includes a stator having a coil, and a rotor. The stator includes main and auxiliary stator magnetic-pole surfaces. The rotor includes main and auxiliary rotor magnetic-pole surfaces facing the main and auxiliary stator magnetic-pole surfaces. When an electric current flows in the coil, an electromagnetic force in an axial direction is generated between the main stator and rotor magnetic-pole surfaces, and an electromagnetic force in a radial direction is generated between the auxiliary stator and rotor magnetic-pole surfaces. When the rotor is displaced in the radial direction, a radial force that acts on the rotor between the auxiliary stator and rotor magnetic-pole surfaces is increased in a direction of the displacement, and a radial force that acts on the rotor between the main stator and rotor magnetic-pole surfaces is increased in a direction opposite to the direction of the displacement.

Abstract

To reduce the possibility that temperature of refrigerant discharged from a compressor of a refrigeration apparatus becomes excessively high by controlling torque of a motor built into the compressor, the compressor includes the motor having rotation thereof controlled by inverter control. An inverter controller controls torque of the motor using inverter control when operation frequency of the compressor is at least one value within a range of from 10 Hz to 40 Hz. When at least the operation frequency is within the range of from 10 Hz to 40 Hz, torque of the motor is controlled, and under a predetermined condition in which temperature of refrigerant discharged from the compressor easily becomes excessively high, a device controller controls devices provided in a refrigerant circuit such that refrigerant sucked into the compressor is placed in a wet vapor state.
