Introduction
- Nema 23 motors are about 6x6x8 cm size - and require _______ amps for driving.
- Xylotex says body length is 3"
Off-the-shelf options
- 5 axis version of controller brain (minus power handling) - can this be used with any power-handling system? - [1]
- An up to .75A brawn module from Sparkfun - [2]
- Any advantage cf. open source RepRap stepper controllers?
- This does offer USB connection, and is open source - [3]
- 3 axis, 3A kit on eBay, $200 - [4]
- CNC Stepper Motor Controller at [5].
Turnkey systems
- 2-axis, 4A, 24V system - [6]
Open source projects
This is a goldmine for drivers: http://reprap.org/wiki/StepperMotor#Stepper_drivers
RepRap 3D printer

Power supply
What if we used power supply units from PCs? They're pretty high current and they can be placed in series for 12 volt, 24 volt, 36 volt, etc, systems. They've got 5 volt taps to run the microcontroller off of. They're ubiquitous and either free or cheap. Jason 00:46, 23 May 2011 (PDT)
Crazy idea - combine inverter and motor controller circuits onto one board
It seems to me that the high cost of both motor controllers and inverters are some pricy power electronics components. What if we could reuse those expensive power electronics components to make a single circuit that can either be an inverter or motor controller? An inverter takes DC power from batteries and creates an AC signal. However, when running motors, you don't need that functionality, because you're taking DC power and running motors with it. So, potentially, with a single expensive piece of power electronics, you could combine inverter and motor controlling capabilities for just a little more than supporting just a single function.
