Motor torque control to reduce possibility of centrifuge rotor accidents

摘要

Controlling the torque of a motor by driving a centrifuge rotor connected to the motor; increasing a motor torque of the motor to a specified level; detecting revolutions per minute of the centrifuge rotor; adjusting the motor torque based on detected revolutions per minute; decreasing the motor torque to a constant torque over a range of revolutions per minute; and increasing the motor torque when the detected revolutions per minute are outside of the range.
