Is there any reason not too? I've got a load of 24v steppers I've ripped out of dead printers. I'd like to use them in a battery powered situation, but I really don't want to have a 20AA battery pack. If I run the 24v stepper coils @ 12V, is it going to damage anything? I realize that they will likely pull double the current they were rated for @ 24v, but is that going to cause smoking motors in the short term?
Thanks!
That should read half the current, duh. But other then the obvious lack of torque, is this going to cause problems? Thanks!
Hi, Richard. No problem at all. Half the current, 1/4 the power, but no ill effects to the motor. Go right ahead.
But if you need +24V for a portable application where you're driving steppers, you're going to need a lot of current, and are going to be burning through those AA batteries like kindling. How about two small lead-acid rechargeables in series?
Cheers Chris
