(OP)
Wondering how you can start a WRM W/O the Strating Resistors racked in and not burn up the rotor windings?

RE: Wound Rotor Motors
Thanks, I was very sure that this was the case. I pulled the string on this matter and found out that they are opening a valve upstream of this pump/motor and allowing it to free wheel on system pressure prior to starting the motor. This limlits the "locked rotor" inrush current.
While I still believe that this is a very risky practice it seems to be allowing the start of these WRM's.
Wierd huh.
