I am using your https://www.pololu.com/product/1205/resources with microstepping through a 90° sweep taking three minutes, for 8 hours a day, back and forth, continuously (part of an art installation). I measured 82°C on the exterior of the stepper motor while in use. Is this okay, or must I attach a heat-sink to its bottom (which would increase the height off the total assembly)?
Thanks!
