Do PMDC motors and SWDC motors require different motor controllers? Answered
I'm looking to run two Etek-R PMDC motors from one 700 amp controller. Will a GE series 700 amp controller work? Upon calling the company that offered it today I received-- through proxy-- the response that the compnay carried no permanent magnet controllers. Is there a difference between pm and sw controllers? I was under the impression that both required the same type of control: varying voltages.
could the company have confused permanent magnet with pulse width modulation?
any explanation is greatly appreciated!
