Frequently Asked Questions

How much can premium-efficiency motors save?

A few percent higher efficiency compounds over thousands of run-hours. On a continuously-running motor, the energy savings often exceed the price premium within a year or two.

Is premium efficiency required by law?

Most integral-HP general-purpose motors sold in the U.S. must meet DOE/NEMA Premium levels. These comply.

Are they VFD compatible?

Yes - the insulation systems suit inverter duty. Verify the turndown ratio for constant- vs. variable-torque loads.
