Title: Centrifuge
Inventor: AKATSU KATSUNORI
IPC: B04B13/00
Filed: 1999-08-11
Abstract: PROBLEM TO BE SOLVED: To reduce the accelerating time of a motor by distinguishing a rotor at the time of accelerating the motor or the rotor and if the rotor is not distinguished, controlling to distinguish the rotor shaft stabilizing at an optional revolution speed to shorten the rotor distinguishing time. SOLUTION: After the motor is accelerated, a rotor distinguishing frequency counter is cleared to be zero. When the revolution speed of the motor is recognized to be <=50 min-1, the rotor is distinguished by a distinguishing means while accelerating the motor. When the rotor is judged to be already distinguished, the motor is accelerated up to a set revolution speed and stabilized. If the rotor is not distinguished, whether the rotor distinguishing frequency counter shows >=4 or not is judged and when showing <=4, the rotor distinguishing frequency counter is increased by one count and returned to the original. When the revolution speed reaches 50 min-1, the motor is stabilized at 50 min-1 and the rotor is distinguished. If the rotor is not distinguished even when the rotor distinguishing frequency counter shows 5, a centrifuge is stopped with the error indication.
