Motor Temp, it’s a hot subject.

Ok, on a small EBike motor of around 500 - 600W’s what temperatures would be acceptable ? Some of the charts you can find are mentioning Type B and F with circa 135 degrees above ambient, is this what you guys are working to.

On my installation the motor is now almost enclosed by the frame and it would be useful to know limits of what’s acceptable and what’s not.

Thanks.
