摘要： A centrifuge includes a rotor, and a motor for rotating the rotor. At least three identification elements provided on the rotor are arranged along a circumference of a circle whose center coincides with an axis of rotation of the rotor. An angular interval between prescribed two of the at least three identification elements indicates a maximum allowable rotational speed of the rotor. One or more of the at least three identification elements indicates a type of the rotor. A sensor operates for detecting the at least three identification elements during rotation of the rotor. The angular interval between the prescribed two of the at least three identification elements is measured in response to an output signal from the sensor to detect the maximum allowable rotational speed of the rotor. The type of the rotor is detected in response to the output signal from the sensor.

摘要： A centrifugal apparatus includes a rotor having a marker for generating an index signal, a motor for rotating the rotor, first and second detectors for detecting the index signal with rotation of the rotor to generate first and second detection signals, an input terminal for receiving supply power, a drive circuit for generating a drive signal from the supply power according to the first detection signal, and first and second switch circuits for controlling the supply of the drive signal to the motor. First and second judging portions are used to detect whether the first and second detection signals are respectfully generated within a given condition. The first judging portion operates the first switch circuit to stop the drive signal from being supplied to the motor when the first detection signal is not generated within the given condition, while said second judging portion operates the second switch circuit to stop the drive signal from being supplied to the motor when the second detection signal is not generated within the given condition. The first and second detectors, judging portions, and switch circuits, respectively, independently operate to provide double feedback loops, so that an overspeed or the like is prevented.

摘要： A centrifuge includes a frame, a damper connected to and supported on the frame for isolating vibrations, a drive unit connected to and supported by the damper, a swing-bucket rotor rotated by the drive unit, an accelerometer for detecting when part of the drive unit contacts part of the frame due to vibrations of the drive unit exceeding a predetermined amplitude, and a control unit for controlling the drive unit based on output from the accelerometer. When amplitude of vibrations in the drive unit exceeds a predetermined value, a portion of the drive unit contacts a portion of the frame. The accelerometer detects an impact caused by the contact between the drive unit and the frame. The drive unit is halted when output detected from the accelerometer exceeds a threshold value for detecting imbalances.

摘要： The rotor data including a model name, a maximum rotating speed, and a rotor identification number of a rotor that is purchased after installation, for example, is stored through the inputting unit in an EEPROM in addition to the rotor data that was stored in the ROM before shipping. The inputted rotor data is displayed on the display in a list image together with the rotor data of the rotor data in the ROM to provide easily selection of the rotor. The inputted rotor data may be displayed with priority to the rotor data in the ROM. The rotor data may further include check data. It may be judged that the inputted rotor data is correctly inputted. If the rotor data is incorrectly inputted, an error message is displayed and the rotary data is not stored. If the rotor data is correctly inputted, the rotary data is registered in the RAM.
