Other Parts Discussed in Thread: DRV8301
I am using this to test a fan motor, but the motor requires a higher amperage (i.e. 40 amps). I can get it to run at lower speeds restricting the amperage to 15 amps. Is there a suggested board to handle the higher amperage or would replacing the 6 FETs do the trick? Looking to get it up to 25k rpm or so. It will go up to about 15k rpm, but higher than that resets the controller, not sure why. If I remove the fan blades, it will get up to about 30k rpm, but then there is a lot less torque needed. Also not sure if the BEMF voltage needs to be taken into consideration at the higher speeds.
If someone could point me in the right direction, that would be great.
