RPM ac motors offer compact, square steel frames for inverter duty and vector duty applications. They are available from stock in totally enclosed fan or blower cooled and drip proof designs from 3 through 1,000 hp.
They handle the most demanding industrial applications in frame sizes that are up to three times smaller than traditional NEMA or IEC motors. RPM ac motors feature low inertia for use on high-response applications and are optimized for use with adjustable speed drives. Applications include extruders, conveyors, crane and hoist systems, converting, web processing and printing, cut-to-length applications, veneer lathes, test stands, traction duty, and winders.
