1/4 HP MOTOR

1/4 HP MOTOR

1/4 HP MOTOR

(OP)
For a  solar powered application we have had success using a 1/4hp 24v dc 1800rpm motor to drive a swamp cooler that normily requires a 1/2 hp ac motor, (although the pully ratio was slightly increased). Now we have upgraded to new sinewave invertor would like to consider an A/C motor replacement. However anyway I cut it I just can not beat the DC motor w ~80%efficiency. Is this basically the best I can do? or is there new type VFD/ repultion type motor kits available that will beat it? Thank You.

RE: 1/4 HP MOTOR

It is possible to get better efficiency with an AC motor. Not sure about the system efficiency considering the inverter and potential drive. Should be able to find a DC input AC output drive out there somewhere, eliminating the DC to AC inverter before the drive.
