Paralleling to MV motors
Paralleling to MV motors
(OP)
Hi all, a colleague of mine is proposing paralleing two 750kW 6.6kV DOL motors on a conveyor (two gearboxes with a fluid couplings)me I am from the old school
I would have seperate breakers and contactors with interlocking between drives. Is there a regulation prohibiting the paralleling of large MV motors?

RE: Paralleling to MV motors
You obviously can't interlock between drives or both motors could not run at the same time.

Each had independent protection.
The motors drove a crushing mill at a mine in Canada. We had six similar crushers.
