Abstract: A centrifuge includes light sources to provide different illumination states depending on the status of the centrifuge to communicate the status of the centrifuge. The light sources, when activated, project light in the centrifuge chamber and through the centrifuge lid. The light sources are preferably light-emitting diodes.

Abstract: Rotor temperature in induction motors is estimated without the need for any direct temperature sensors, by using only computer calculations based on data readily available in the motor control center. Thus for any given motor, it is generally possible to predetermine a relationship between rotor temperature and rotor resistance, so that by determining rotor resistance, rotor temperature can be calculated. Rotor resistance, in turn, can be calculated from measured information relating motor slip and motor torque. Any of several methods can be employed for determining torque and slip. Temperature estimation can be obtained by use of equivalent circuit methods, and additional relationships can be obtained from a simplified equivalent circuit.
