# Blue Chip Automotive Duty Motors TEFC Motors that Exceed the Toughest Standards in the Automotive Industry Today... Marathon Electric’s Blue Chip XRI ® Automotive Duty Motors are designed tough with built-in reliability for years of trouble free service. Totally enclosed severe duty construction and additional epoxy coatings protect against the harshest environments, thus prolonging life and reducing unnecessary downtime. Rugged die cast aluminum rotors are precision balanced. This reduces overall system vibrations, thereby increasing equipment longevity. Vibration tests are documented and shipped with each motor as standard. Our Blue Chip XRI ® Automotive Duty Motors are inverter duty rated and incorporate our exclusive MAX GUARD ® insulation system which combines corona resistant magnet wire and a unique "low stress" winding configuration. The Blue Chip XRI ® Automotive Duty Motor offers no lead length restrictions and provides for power matched performance with all manufacturers of AC drives. The Blue Chip XRI ® Automotive Duty Motors exceed EPAct and NRCan efficiency requirements and are energy compliant to the highest efficiency levels in the motor industry as promoted by the Consortium for Energy Efficiency (CEE). The Blue Chip XRI ® Severe Duty motor meets Ford’s EM-1 specifications for automotive duty motors. These motors incorporate features that guarantee years of high performance in the most demanding automotive applications from parts forming, metal cutting, and assembly to test stands. These motors meet or exceed the vibration, temperature rise, and sound levels contained within the motor industries toughest specification. The Blue Chip XRI ® IEEE-841 automotive duty motor meets General Motors 7E-TA specification for sound levels, vibration, and temperature rise. These motors incorporate an Inpro/Seal ® VBX bearing isolator for added protection against corrosive environments. This added protection shields vital components from metal chips, cutting fluids, and oil-based contaminants. The Blue Chip XRI ® Severe Duty and Blue Chip XRI ® IEEE-841 motors are provided with actual test and vibration data for added assurance of quality. 

### U-Frame Motors that are Driven to be the Best... Our U-Frame motors are available to meet a wide range of performance requirements, from 3/4 through 100 horsepower. These motors incorporate rugged cast iron construction that resists vibration and shock in the most demanding industrial applications. Marathon Electric’s U-Frame motors have built-in features like premium energy efficient designs, C-Face kits, and power matched performance with all AC drive manufacturers. These industry work horses provide excellent value and dependable performance you can count on in tough, dirty, oil-laden environments. These motors meet DaimlerChrysler NPEM-100 and NPEM-105, Ford EM-1, and General Motor’s GM-7EH and GM–7EQ specifications.
