Well I think one of my stepper motors may be bad. I have tried it with every driver I have. No mater which one I try it gets up to about 110f when just sitting there doing nothing. When I run it its very easy to stop.
Disconnect and look up the spec sheet for the motor, measure each legs resistance, you might have a short.
Yup thats the next step though I’m almost positive there is a short in one of the coils.
There’s almost never a time when salvaging motors is a good idea.
Normal motors are show 16ohm and the weird one is 16.5 on both coils
One coil might have become shorted to the other - normally they are completely isolated from one another, so if your multimeter shows anything other than out of range for the resistance between the coils, you should toss that motor.
I have it wired in series so mesuring each coil should be 16 ohm. That’s a good idea checking for a short
Well, wait a second - your imperialistic units were confusing me there for second. Steppers get warm when they are powered on, pretty much regardless of whether they are moving or not. 43°C doesn’t seem like much, mine get a wee bit warmer.
And actually, if a coil was shorted onto itself, the motor should heat up less than regular - we’re running them constant-current and not constant-voltage, after all.
Well for what its worth switching from serial to parallel wiring has solved the issue and provides more torque.
