Abstract:
A system for measuring temperature in an electric motor includes an interface communicatively coupled to a motor and a processor coupled to the interface. In various embodiments, the processor is configured to obtain access to a temperature-measuring electrical path, where the temperature-measuring electrical path rotates relative to a magnetic field, and the temperature-measuring electrical path has no net induced voltage due to magnetic field as the temperature-measuring electrical path rotates relative to the magnetic field. The processor may be further configured to determine a resistance associated with the temperature-measuring electrical path, and determine a temperature of the motor based at least in part on the resistance.
