Abstract
A centrifuge including: a rotor rotating with a sample contained therein; a rotating shaft rotatably engaged with the rotor; a motor rotating the rotor and the rotating shaft; a belt transmitting rotational force of the motor to the rotating shaft; a rotor speed detecting unit detecting a rotation speed of the rotor; a motor speed detecting unit detecting a rotation speed of the motor; and a control unit controlling the motor, wherein the control unit calculates a signal for controlling the rotation speed of the rotor on the basis of a signal from the rotor speed detecting unit and controls the motor on the basis of a signal from the motor speed detecting unit and the calculated signal.
