I´m looking for a card to drive the motor NISCA NC5475 like a servomotor.
I´m want to make an X-Y table, we have a card that out the signals to control the driver.
Interesting to come across this question, I was looking for the spec's on this motor, considering using it to drive a spindle on a small desktop cnc pcb cutter.
To make this, or other commutator type (brushes), motor work similar to how a servo works take a close look at how many modern printers are now made. They utilize a type of timing wheel with with a photo sensor to keep track of position. I think you'd also have to monkey with the gear/pulley ratio to get a usable speed and torque.
It's a doable endeavor however you may consider doing what I'm doing. Use steppers to run your x/y/z end the NiSCA NC5475 to drive the spindle. I'll probably add the timing wheel and photo sensor also so that I can keep track of the rpm.
This may help in calculating the performance on this motor. It's a semi English page to the manufacturer's website on this motor model. http://www.nisca.co.jp/motor_eng/dc_nc5475.html
Good luck with it,
