The VESC / BLDC autodetect was used to get initial parameters and the motor itself runs smoothly.
Motor 130 kv Alien sensored motor
Supply 36 volts ( Currently via mains lab supply)
Integrator limit = 155
BEMF Coupling = 650
At full pump speed we have typically 40 amps motor current as shown on the BLDC tool and 80% duty cycle, within a short time we hit 80 degrees on the FET temperature.

Considering the fact that the VESC is used for a few (quite a few) Skateboard designs where the user is on the board up and down hills something must be wrong if we can only achieve a few minutes run time before the VESC overheats.
I have run it in sensored, sensorless and hybrid modes. Obviously sensorless mode does not work too well at low speeds.

Any thoughts would be appreciated as this cannot be correct as the specs for the VESC seem way above what we are actually using ?
