The X$D Ultra® 841 meets or exceeds the IEEE 841-2001 Standard. With an advanced insulation and bearing system, a test report of each motor to ensure performance, 5 year warranty and all the advanced features that come with it, the X$D Ultra® 841 is the most durable and reliable motor you can buy.
The X$D Ultra® 841 family of products range from 1-250 HP and is built to the highest standards to maximize your return on investment. X$D Ultra® 841 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® 841 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.
