Title: Sanyo Denki Stepper ?'s
Post by: Overloaded on May 06, 2012, 10:48:25 AM

Hey folks,
  I recently picked up a batch of Sanyo Denki stepper motors.
Some are ... Type : 103-845-6741     12-300 V     6.7 A   Stall Torque 3.4 Nm (Should be perfect with a Gecko ?)

I found gads of info on these, but cannot find any info on the others, which are:
Type : 103H82236540    12-300 V       9A      7.05 Nm

I'm trying to find a suitable driver for the 9A model. It's over the Gecko 7A limit so I suppose it would destroy the Gecko ... or is there a way to limit the load on the driver and use the combination anyway ?

Thanks first,
Russ

The Gecko's dictate the current, not the motor. Set the Geckos for 7 amps and your good, but you'll lose about 25% of the rated torque (7÷9).

Larken makes a 10 amp drive. http://www.larkencnc.com/motion/steppers.htm

Gerry,
   The Gecko set at 7a is no resistor installed.. Just wasnt sure if it was protected internally at that point or if it would fry, Thanks !

Thank you Ian, just what I was hunting for.. Perfect!
