    Abstract: 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,

    Abstract: The magnetic bearing control device (1) has a motor drive circuit (13) provided with an inverter (13a) for driving the motor (4) capable of generating an electric power, the inverter being controlled by an inverter control circuit (14), and an over-speed detection circuit (17) for detecting the number of revolutions of the rotor (3) that is being rotated by the motor (4), the rotor being supported in non-contact manner by a magnetic bearing (5). When the over-speed detection circuit (17) detects that the rotor (3) is being rotated at a preset number of revolutions or more, the motor drive circuit (13) performs a switching operation of a switch portion 13c provided in the motor drive circuit (13) to separate the inverter (13a) from the motor (4) and connect the motor (4) to a regenerative circuit (13b), whereby the magnetic bearing (5) is driven and controlled, employing a regenerative electric power of the motor (4).

    Abstract: A machine tool comprises a spindle unit for raising a spindle on which a cutting tool is mounted by a magnetic force and supporting the spindle. The spindle unit carries out feedback control so as to maintain the spindle in its target position in the radial direction. A feeder for feeding the cutting tool to a work comprises a servo motor for moving the spindle unit relatively to the work. A feeding controller for controlling a feeding operation of the feeder controls the speed of rotation of the servo motor on the basis of feed speed data stored in a memory. The feed speed data comprises a first feed speed corresponding to the time when the cutting tool cuts through an end surface of the work crossing the direction of feeding and a second feed speed corresponding to the time of normal working and higher than the first feed speed.
