Medium vs low voltage and HP ratings
Medium vs low voltage and HP ratings
(OP)
What is the break point where you would consider using medium voltage(above 600v) in lieu of low voltage (below 600v) for motor HP ratings?
Thanks.

RE: Medium vs low voltage and HP ratings
If you are looking purely at bare motor costs, I'd guess the breakover point is somewhere around 300 hp, but others with more recent experience can correct me.
Other factors - constant speed versus adjustable speed. Full voltage start versus soft starter. Frequency of starts. The list goes on.

If the medium voltage available is 13kV then the 100 HP motor will probably stay on 480V or 600V.
