Request Information
50 HP, 1800 RPM, NEMA Frame 326T, 230/460 V ,
    The X$D Ultra® family of products range from 1-300 HP and is built to the highest standards to maximize your return on investment. X$D Ultra is a complete cast iron motor exceeding NEMA Premium® Efficiency standards. The Six Star Bearing System™ ensures long bearing life and is complemented by an overall vibration of 0.04 ips (inches per second), which is half of IEEE-841 standards. The X$D Ultra also, incorporates GEGARD2000™ insulation system which has the ability to withstand repeated 0.1 microsecond rise time/2000 volt spikes for 460 and 575 line voltages. All motors are inverter compatible and have the speed range capabilities stamped on the nameplate.
