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.
