Hi guys
I just smoked two motor driver like these:
http://www.ebay.com/itm/0-36V-Rated...693?pt=LH_DefaultDomain_0&hash=item2ecdfe19fd
here is the contril pins:
The motor run about 1-2 seconds, a "pop" sound is heard, then gone. No physical damage can be seen by eyes. No mosfet is warm/hot, they are all still at room temperature.
it looks like on normal PWM mode, the motor is switched between on and brake, is there a reason for this?
Because I think that might be the reason why my motor controller is smoked.
My DC motor is 250W, 24V, no load current is about 2A, rated current is about 15A. Power by two 12V sla batteries.

here is the contril pins:
- Forward: DIR = 1 PWM = PWM
- Reverse: DIR = 0 PWM = PWM
- Brake: DIR = X PWM = 0
