Regal Beloit Corp. says it has developed its most energy-efficient motor in NEMA Premium® frame sizes. According to officials, the NovaMAX motors are ultra-efficient, electronically commutated permanent magnet motors. NovaMAX motors are packaged in standard NEMA frame sizes and mounting dimensions enabling simple substitution in retrofit applications. Available in frame sizes from 48 to 280, the NovaMAX motors are compatible with readily available VFDs from most leading manufacturers.
With a 5% to 20% reduction in electricity costs compared to NEMA Premium (IE3-level) induction motors, NovaMAX officials said the motors can deliver payback in 18 months or less with motor efficiency meeting and or in some cases exceeding IE4 and even the proposed IE5 efficiency standards.
