I realize this is not about PLCs, but there have been a lot of questions answered on here about motors so I thought I would place this here.
What is the difference in torque between an AC Motor and a DC Motor? I just got off the phone with an AC Drive tech (I am thinking of going from DC Drive/Motors to AC Drive/Motors) and he informed me that the torque of a 1 HP, 1800rpm, 90VDC motor (the motor shows 36 in/lb) was different than the torque of a 1 HP, 1800rpm, 230VAC motor (3 lb. ft.) I do not see how this is possible. I mean torque is torque and if the HPs are the same should not the torques be the same?
Looking at the above examples, they look the same. (36in.lb=3 lb.ft)
I thought that I would be able to directly swap out the one motor for the other....
Thanks in advance,
Bob
