Hey folks.
Still working on my bandsaw issues and had a
question about 3 phase motors.
I need a motor that produces 3 hp at 600 rpm
(direct drive).
If I use a variable frequency drive to drive a 3
phase motor at a slower speed than its rating will
I get as much power from it as its rating?
Will the motor draw as many watts at the slower
speed? Produce as many newton meters?
Would it be better to start with a 3450 rpm motor
or a 1770 rpm motor?
Should I start with a higher hp motor and then
slow it down?
Thanks in advance,
Brad
