I'm building a small desktop CNC designed for milling PCB's, I need small DC motors w/ encoders (NEMA17 mounting style)
I need something like this, but a DC motor instead of stepper motors. I simply just can't get the accuracy from step motors. Brushed motors preferred & they need to be less then $40. I was hoping someone might know about something about this.
When using induction motors, we can scale down the physical size by increasing the rated frequency. Take for instance this 200hp 60HZ induction motor at 2127lbs, vs this 200hp 400hz induction motor at 85lbs. So for weight sensitive applications like aeronautics or EVs, the 400hz motor is the clear winner.
But what if we want to use a separately excited would field DC motor?
