摘要： A sensor-equipped rolling bearing assembly includes: a cylindrical fixed bearing ring fixed to a vehicle body; a rotary bearing ring rotatably inserted through the fixed bearing ring and having a wheel-mounting portion on an outboard side thereof; and plural rows of rolling elements rollably interposed between these bearing rings. The bearing assembly is provided with a case member having plural displacement sensors which are circumferentially arranged at predetermined space intervals and which detect gaps between themselves and an outside surface of an inboard end of the rotary bearing ring. The case member is mounted to the inboard end of the fixed bearing ring.

摘要： A bearing apparatus include a rotor having a flange portion, a foil bearing for supporting the rotor in a radial direction, and a magnetic bearing for supporting the rotor in an axial direction by an electromagnet, and a control portion for controlling electric current supplied to the electromagnet. The control portion controls such that a first electric current is supplied to the electromagnet so as to cause the electromagnet to attract the flange portion so as to support the rotor in the axial direction. The control portion also controls such that when the number of revolutions of the rotor is smaller than the number (R1) of revolutions at which the rotor floats off the foil bearing when supplying the first electric current to the electromagnet, a second electric current larger than the first electric current is supplied to the electromagnet.

摘要： If the ambient temperature of a pressure volute measured by a temperature sensor exceeds 0° C., a compressor is instantly started at normal operation. If the temperature of the pressure volute measured by the temperature sensor is 0° C. or lower, there is a possibility that a rotary vane may be adhered to the pressure volute due to a congelation. Therefore, vibration along the axial direction is given to the rotary shaft by way of an axial magnetic bearing. If the vibration amplitude of the thus given vibration exceeds a predetermined value, the compressor is started at normal operation after idle operation. On the other hand, if the vibration amplitude is lower than a predetermined value, it is determined that the thus given vibration is unable to eliminate the adhesion of the rotary vane due to the congelation, and the heater is actuated to heat the pressure volute only for a predetermined time. Thereafter, the ambient temperature is detected again, and if the ambient temperature exceeds 0° C., the compressor is started,
