Thanks edison123,
I think you answered my primary question if which what you are saying is this motor is only designed to operate within 10% of 230 which would be O.K. at actual 208 voltage but under that there may be problems.
My only problem with the transformer change is there are other...
waross,
Thanks for the reply,
Would operating this 230v motor at 208 volt decrease its tourqe and make it difficult to get the motor & fan up to speed causing it pull greater amperage? The actual brake horsepower needed for the fan was calculated at 2.84 BHP.
Also if this motor is "usable at...
JHanson717 & rbulsara,
Thanks for the response.
The closest fan to the panel has about 50 feet worth of wiring and is fed with a 8 awg. It only drops to 200v at start up but it still never gets up to speed and trips the breaker after turning at half speed for 10 seconds or so.
The farthest...
Hey guys,
I have (5) new sidewall propeller exhaust fans with 3HP 115/230 volt, 60 Hz, single phase 1725 Rpm fan motors with a 1.0 service factor. At the bottom of the tag it also says usable at 208 volts 15.5 amps. The system they are operating on is 208 volt 60 Hz.
I am having trouble with...
