RPM AC
The ABB Baldor-Reliance RPM AC motor delivers high torque density in a compact, laminated steel frame—ideal for precise, variable speed control.
DESIGNED FOR POWER. REFINED FOR PERFORMANCE
When space is limited, the ABB Baldor-Reliance RPM AC motor delivers. Built with a laminated steel frame, RPM AC motors offer high torque density and custom power/speed ratings to meet the demands of variable speed applications.
Designed to fit where traditional motors can’t, RPM AC motors can be up to three frame sizes smaller than standard NEMA or IEC motors—without compromising performance. Multiple enclosure options ensure flexibility across diverse environments.
Drawing on decades of experience in variable speed DC technology, the RPM AC motor features a square laminated frame, optimized cooling and premium insulation for exceptional torque performance in a compact, efficient design.
