<P>PROBLEM TO BE SOLVED: To provide a centrifugal separator which can prevent denaturalization of a sample due to excessive centrifugation and/or temperature rising by decelerating the rotor quickly in power interruption conditions and recover the sample when a power interruption occurs and also prevents damage of bearings of driving parts due to high-speed rotations when lubrication and cooling are poor in power interruption conditions. <P>SOLUTION: When a power interruption detecting circuit 20 detects a power interruption, the operation is switched to a deceleration control by a controller 4, and power is supplied to the centrifugal separator itself through the regenerative electric power. For this purpose, an auxiliary power source 6 being sufficient to start the deceleration control during a power interruption is provided, and an electric path interrupting means 5 for avoiding distribution of power to equipment other than the centrifugal separator sharing the power system is disposed. <P>COPYRIGHT: (C)2013,JPO&INPIT |
