Stepper Motor Temperature
Stepper Motor Temperature
(OP)
I'm currently running a 12V 1.8deg stepper motor, doing a short sequence of about 4 secs duration: one 180deg move, one 90, another 90, with about a second's stopping between each move. There is no load on the shaft.
But!! It is running at about 70deg Centigrade (and still rising), which is about 160F! This is after about 20 mins, and it is sat atop a couple of heatsinks, which are also now very toasty!
Is this normal? Is it going to get hotter when I give it some load?

The current it pulls is fine, a bit less when it is moving but not by much. It's rated at 0.4A, I assume that's 0.4 per coil, as together they pull 0.8A.

Could you test the motor out of your circuit by feeding it with a 12 V car battery and check the performance?
