Hi,
I'm working on a project that uses a miniature pager motor (6 mm diameter) serving as an actuator for a feedback control system. It is a coreless DC brushed motor.
I read that the expected lifetime of these motors is only 100 hours and I'm looking for any recommended ways to increase the life span. Any ideas??
My application is switching directions, and I've reduced its operating voltage to 3.8 V (average ~2 V) -- motor is rated to 4.5 V. I think there could also be some arcing between the brushes and commutator that I can reduce. I've read a little about arc suppression circuits, would this help and how do I implement one?
some commercial vendors (e.g. maxon motor) rate their 6 mm brushed coreless motors to 500-1000 hr lifetime. But they cost 75 bucks! the pager motor I'm using is 3 dollars and works fine (other than the rated life). any thoughts would be appreciated!
