  • Appl. No: 17/151710
  • Application Filed: January 19, 2021
  • Claim: 1. An electric motor system comprising: an electric motor; a motor driver electronics (MDE) component configured to operate the electric motor, the MDE component comprising: a power card comprising one or more components; a heatsink comprising a thermoelectric generator; and a controller configured to: receive voltage data associated with the thermoelectric generator; determine a temperature reading based on the voltage data; and enact an action associated with the MDE component based at least in part on the temperature reading.
  • Claim: 2. The electric motor system of claim 1, wherein the thermoelectric generator is located on the power card proximate to the one or more components.
  • Claim: 3. The electric motor system of claim 1, wherein the thermoelectric generator comprises a plurality of Peltier cells between a first junction and a second j unction.
  • Claim: 4. The electric motor system of claim 3, wherein the first junction comprises a contact with the one or more components.
  • Claim: 5. The electric motor system of claim 3, wherein the plurality of Peltier cells are arranged in series.
  • Claim: 6. The electric motor system of claim 3, wherein the plurality of Peltier cells are arranged in parallel.
  • Claim: 7. The electric motor system of claim 1, wherein the controller is configured to enact the action associated with the MDE component based on the temperature reading exceeding a threshold value.
  • Claim: 8. The electric motor driver of claim 1, wherein the controller is further configured to display the temperature reading on a user interface for an aircraft.
  • Claim: 9. The electric motor system of claim 8, wherein the user interface is configured to receive a user input; and wherein the controller is configured to enact the action associated with the MDE component further based on the user input.
  • Claim: 10. The electric motor system of claim 1, wherein the MDE component further comprises a temperature sensor.
  • Claim: 11. A method comprising: receiving, by a controller on a motor driver electronics (MDE) component, voltage data associated with a thermoelectric generator, wherein the MDE component is configured to operate an electric motor, and wherein the MDE component comprises a power card including one or more components; determining a temperature reading based on the voltage data; enacting an action associated with the MDE component based at least in part on the temperature reading.
  • Claim: 12. The method of claim 11, wherein the thermoelectric generator is located on the power card proximate to at least one of the one or more components.
  • Claim: 13. The method of claim 11, wherein the thermoelectric generator comprises a plurality of Peltier cells between a first junction and a second junction.
  • Claim: 14. The method of claim 13, wherein the first junction comprises a contact with the one or more components.
  • Claim: 15. The method of claim 13, wherein the plurality of Peltier cells are arranged in series.
  • Claim: 16. The method of claim 13, wherein the plurality of Peltier cells are arranged in parallel.
  • Claim: 17. The method of claim 11, wherein enacting the action associated with the MDE component based on the temperature reading exceeding a threshold value.
  • Claim: 18. The method of claim 11, further comprising displaying the temperature reading on a user interface for an aircraft.
  • Claim: 19. The method of claim 18, wherein the user interface is configured to receive a user input; and wherein enacting the action associated with the MDE component is further based on the user input.
  • Claim: 20. The method of claim 11, wherein the MDE component further comprises a temperature sensor.
  • Current International Class: 02; 64; 64; 64; 64
