What's The Difference Between 90vdc And180vdc Motors? And Dc Rpm Question

[calstar]

Any applications where one is better than the other? Does the 90 always use 11ovac input and the 180 220vac input?

I read/saw somewhere that a dc motor should not be run at more than 70% of its max rated rpm continuously or it will overheat, true?

thanks,

Brian

Basically, yes.

You need to look at the individual motor ratings.
