I am using an Infineon controller to power my XB-500. It works great for a few minutes until it gets warmed up. I then start to have problems engaging the throttle at lower speeds. Sometimes I get a screeching sound from the motor until I back off on the throttle and then slowly ramp it back up.
Anyone have clue what might be going on with it? Is this from the motor overheating or the controller?
Has anyone else ever had their motor squeal? It is a high pitched sound and the pitch will vary with the throttle input.
