Hi guys,
I'm trying to design a brushless motor for an EV with temperature sensing for both the copper coils in the stator and the permanent magnets in the rotor, but I'm not sure how to add a temperature sensor on the neodymium magnets in the rotor. Wouldn't the high levels of varying electromagnetic fields throw the readings off? Or would the system have to compensate for that somehow, e.g., using a low pass filter?
Of course, the bigger question would be whether the permanent magnets ever generate significant (if any) heat during normal operation anyway. :)
