Re: build your very own Lebowski controller !

Hi,

I've been using VESCs to control 6kW BLDC motors but have had to current limit the motors quite severely to avoid damaging the VESCs. I've been planning to make my own and was wondering if a Lebowski MCU would work?

I'd want:
bidirectional control
control via PPM, also known as servo signals.
high startup torque.

My motors do have hall sensors built in.

Which chip would suit me best and how much would it be to the UK?

Thanks!

My chip does not take PPM, you would need to translate this somehow to an analog throttle signal and a forward/reverse signal.

That wouldn't be the hardest thing to do, nothing like driving the motors really.
