So i got an idea after smoking my sensorless motor on a hill. Powered up the hill and noticed smoke coming from my board, the motor is toast. So my idea is to measure the motor winding temperature without sensors via VESC and its ability to measure motor winding resistance, using the following formula for temperature coefficient of resistance. Would like everybody to chime in and start the discussion to see if this is even possible, thanks!
Here are some links:
The things i dont know are:
- Is the VESC able to measure the motor resistance while it is commutating the stator
- Does the VESC have enough processing power to do the calculations
What should this be used for: It would be cool to integrate this into the many variations of Android and IOS VESC telemetry/monitor apps @Ackmaniac . There are a lot of folks here that have unsensored motors, and i think it would be nice to know the temperature of the motor. If the VESC cant measure motor resistance while riding it would still be useful if it could measure it when you stop.
