A friend asked me if I could develop a low-cost power driver for toy/hobby DC motors so he could use it with his microcontroller-based small electronics toy projects. Challenge accepted, the concept ...

He uses the ever-popular Rigol DS1054Z to demonstrate the differences between a handful of brushless motors when rotated by his handheld drill at a constant RPM. Not only is he able to identify a ...

I'm upgrading the motor to use a 4kW brushless hobby motor, which is roughly 5hp peak. Realistically, I expect around 1kW continuous (1-1/3hp). I chose a BLDC over VFD induction drive because A ...

Hobby BLDC motors abound these days, and you might even have a few spares tucked away on the shelf. This algorithm, when applied on the motor controller electronics, can give us the chance to ...
