I'm keen to get a DC Brushless motor (DCBM) going much like Jeremy did for his spindle project ( is it really 2 years ago?).

Mach claims to have a PWM output, has anyone tried using that to drive the DCBM driver module?

I'm hoping that this is a solution to the noise my router makes! Also most routers aren't rated for more that 3 or 4 minutes running anyway. I typically run mine for up to 1 hour.

the duty cycle topic is discussed else where
