Abstract
Systems and methods for sensing the temperature of the rotor magnets of an electric motor are provided to facilitate the determination of motor performance characteristics such as the torque of the rotor.
Claims25
An electric motor system comprising:
- an electric motor;
- a temperature sensor mounted inside the motor capable of measuring local temperature and generating a temperature related signal;
- a processor that utilizes the temperature signal from the temperature sensor to determine an output mechanical torque generated by the motor.
A centrifuge, comprising:
- an electric motor having at least one temperature sensor;
- a processor that communicates with the temperature sensor to determine an output mechanical torque generated by the motor;
- a motor shaft;
- and
- a specimen holder, connected to the motor shaft.
