 MARATHON MAGNAPLUS® generator ends offer powerful performance, reliable power generation, and easy installation.

PRODUCT FEATURES

  • All three-phase generator ENDS are 12-lead reconnectable, providing voltage and phase flexibility. More than 20 stock models ranging from 5–430 kW (60 Hz) and 5–425 kVA(50 Hz).

  • Dedicated single phase models, offer a price advantage with units in stock ranging from 4 to 155 KW

  • EASY MOUNT SAE ADAPTERS are provided with every generator to simplify coupling to the prime mover. Generator foot mounting dimensions are not affected by adapter choice. Special adapters can be ordered for any automotive engine as well.

  • Two bearing models are available at no extra cost, with standardized shaft sizes to match commercially available pulleys

  • THE SE350 VOLTAGE Regulator, provides 1% voltage regulation and offers commercial features such as under speed protection and stability adjustment.

  • Optimized Electrical Design, with four-pole, brushless windings, utilizing a 2/3 pitch design to minimize harmonic distortion. The main rotor, utilizing Marathon Electric’s unirotor construction, provides exceptional wave shape and voltage balance. The unirotor construction method incorporates full amortisseur windings facilitating parallel operation and distorting loads.

  • Enhanced Ventilation, created by a high efficiency cast aluminum fan and optimized internal air flow patterns, maximizes heat transfer and minimizes hot spot differentials for extended winding life. Durable aluminum alloy fans avoid breakage problems associated with welded steel or plastic fans.

  • Fully Guarded for operator safety and generator protection. No rotating or electrically energized parts are exposed. All openings are covered by louvers or screens.

    Heavy Duty Bearings are double shielded and pre-lubricated for the life of the bearing. This helps resist contamination and ensures a minimum B-10 life of 100,000 hours.

  • Class H Insulation System, utilizes an unsaturated polyester varnish for optimal insulation life and superior moisture protection. A tropical insulation is added for increased environmental protection. Field windings are wet wound with epoxy and designed to withstand over speeds of 125%. All windings are100% copper with class H insulation.

  • Design Specs and Agency Approvals. All MAGNAPLUS® units meet NEMA MG1-22, BS5000, CSA C22.2 and IEC 34-1 requirements.

GENERATOR SIZING INFORMATION

IN ORDER TO SUPPLY YOU WITH THE CORRECT GENERATOR END, OUR STAFF WILL NEED YOU TO SUPPLY THE FOLLOWING INFORMATION

GENERATOR KW OUTPUT We cannot determine for you the correct output generator end for your application. We have provided some general KW output versus horsepower guidelines on our FAQ page, but you need to make the final determination.

SAE ENGINE ADAPTER AND FLYWHEEL COUPLER SIZE It is impossible for us to determine this for you. YOU have to supply this information to us. Sometimes you can get the SAE numbers off of the old generator end, and if it's a MARATHON generator end, we can have the factory look it up, if you supply us with the nameplate data. MOST of the time, you're going to have to disconnect your existing generator from your engine, and compare the measurements against the SAE ENGINE ADAPTER AND FLYWHEEL COUPLER MEASUREMENT GUIDE.

If you call us with only the make and model of your generator, unless it's using a MARATHON generator end, we cannot determine the correct SAE engine adapter and flywheel coupler size.

 

WE'LL SHIP YOUR MARATHON GENERATOR
RIGHT AWAY!

AND COMMON CARRIER SHIPPING IS FREE, THAT'S RIGHT...FREE SHIPPING

(Our normal shipping time is three days after you place your order. This is so that we can mate your generator end with the correct engine adapter and flywheel coupler, then paint it. We can ship your generator end the next day, but there is a $150 fee to put your order at the front of the line. Please call for this service.)
