According to my old Superior Electric documentation, both of the steppers are 6 wire, with the MO62 having a double-ended shaft.Originally Posted by Smackre
A Gecko 201 will do the job. The motor curves suggest that for the best performance that a voltage around 36 Volts DC be used.
The best source for a power source would be to check out the power supplies on e-bay and see if you can find one in the voltage range of 28 volts to 36 volts DC with a current rating of around 10 Amps DC. Otherwise, you can visit some of the sites advertised here on CNCZone.
Hope this helps.
