Can I get a more efficient single phase than leeson wattsaver?

[bsaint]

I'm looking for the most efficient 1-1/2hp single phase motor. I think its the wattsaver by leeson. It's only 13a at 115v and 6.6 at 230.

Anyone find anything better?

Electric motors are mature technology. There are no appreciable efficiency gains from brand to brand when comparing apples to apples.

The low line currents are due to the start and run capacitors.

Bro have you even researched motors? They range from 19a @ 120 to 13a @ 120. You know what has changed? Technology in manufacturing which can improve even a beaten to death product.

Old news. Capacitor motors vs non-capacitor. All its really doing is fudging the power factor. If your PoCo only charges for kWh you aren't paying for the overhead anyway.

There are premium efficiency lines. I know baldor makes them and the current is substantially lower than the standard efficiency. They are both capacitor start capacitor run motors.

I don't know if they are made as small as 1 1/2hp

what RPM?

Dude you are out in left field. What you're talking about doesn't apply to anything I'm talking about.
