1 MARATHON ELECTRIC Since 1913, Marathon Electric s name has been recognized for engineering excellence, custom-designed products and an extensive product line of industrial quality motors. Available in all popular enclosures from 1/12 HP through 3000 HP and in a variety of mounting configurations, Marathon Electric s unique designs provide more ways in which to add accessories, such as blowers, brakes and encoders, to our motors than anyone else in the motor business. Our state-of-the-art lab facilities are equipped and staffed with the finest resources available to ensure successful utilization of our products. Finally, as the preferred supplier of motors to most of the top drive manufacturers in North America, we have what it takes to be a leader in understanding the interaction of drives as they are applied with AC induction motors.

6 1. From our homepage, click on the Motors link. From the Motors page, enter in the Marathon Catalog number or Model number. Then click on Model number in results window. (Note: If you already have a Marathon Electric motor and are looking for the performance data, make sure the model number off the nameplate is what you use for your search. Ex. 056H17T5301). 2. The Motor Model Details page will appear. You will be able to print dimensional drawings and connection diagrams in PDF format for the motors. Under the Technical Data section, click on the link, Certification Data Sheet. 3. Your results will look similar to the example shown to the right for Marathon s 1/2 HP, Black Max motor, model # 056H17T5301. It s that easy! 10
