Does anyone know who makes a power supply for the following stepper motor?



Holding torque-Nm (oz/in) +/- 10% 8.7 (1208)
Rated voltage 2.7
Rated current per phase (amps DC) 6.0
Resistance (Ohms) +/- 10% 0.45
Induction (mH) +/- 20% typical 5.1
Motor length (mm) 118
Rotor inertia (g-cm^2) 2700
Weight (kg) 3.8

Just about any power supply will work. It really depends on how many motors your using, and what drives your driving them with.

Gecko drives. Problem is finding a power supply rated for the 6 amp motors.

Go with a rewound microwave transformer or a torroid. Microwave transformers are very inexpesive but torroids will cost you a little more but they can be customized also.

I'm looking for a power supply that's off the shelf. Not home made.

With 3 motors rated at 6A each, you only need at most a 12A supply. How many wires do the motors have, and how are you wiring them? 8 wire motors wired bipolar series would possibly only need a 6A supply. Check out the Gecko White Papers at their website, it explains a little bit about what size power supply you need.

I'm using 4 motors. Two wired parallel, to drive X axis gantry. They are bipolar 4-wire.
