MAGNAPLUS® GENERATORS

Innovation, Performance, Reliability 5 – 430 KILOWATT • 190 – 600 VOLT

Proven top performers in every respect, MAGNAPLUS® generators offer powerful performance, reliable power generation and easy installation. Ruggedly constructed with solid-state technology the SE350 voltage regulator, included with all standard equipment, is a solid performer.

MAGNAPLUS® designs offer an optional, field-adaptable, permanent magnet generator which can be coupled with our PM300 or DVR®2000 voltage regulators. This flexibility in configurations allows for application to the most demanding installations including loads that produce harmonic distortion as well as those requiring fault current support.

Constructed for extended life by utilizing Marathon’s exclusive uni-rotor construction, featuring a UL recognized class H insulation system and long-life bearings, MAGNAPLUS® designs are the ideal general purpose generators for standby as well as prime power markets such as:

• Agricultural
• Marine
• Construction
• Commercial Buildings
• Rental Markets

Product Features

• Choice – More than 20 stock models, all 12 lead reconnectable, providing voltage and phase flexibility. All are capable of modification to a variety of standard and optional conduit box arrangements to meet customer requirements and ease installation.

• 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.

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

• Optimized Windings with brushless exciter. The 2/3-pitch design is utilized to minimize harmonic distortion.

• A Class H Insulation System that is recognized under UL1446 and is suitable for submission to UL2200 application approval

Marathon generators power industrial, agricultural, marine, military and transportation applications worldwide.

Marathon Electric maintains an extensive technical research and development effort to improve existing products and develop new ones. Marathon Electric leads the way with technology for power generation, including the patented DVR® 2000 Digital Voltage Regulator and the patented high motor inrush starting MAC design.

LIMA® MAC GENERATORS – 5-300 KILOWATT • 120-480 VOLT

M – Motor
A – Application
C – Characteristics

For more than thirty years, the LIMA(r) MAC line of superior motor starting AC generators has been the preferred choice of generator for demanding motor applications.

Product Features

Brushless, self-excited, self-voltage-regulated
• No external regulator, current or potential transformers
• Start and run 1 HP/kW 3-phase, Code G induction motors
• Inherent Volts/Hertz over frequency range of 40-65 Hertz
• Inherent 500% of rated current in fault-clearing capability
• Drip-proof (IP23) enclosure
• Single- or two-bearing construction
• CSA, CE, and ISO 9002 Certified

TYPICAL SPECIFICATIONS

The LIMA(r) MAC, manufactured by Marathon Electric Manufacturing Corporation, is a brushless, synchronous, self-excited, self-voltage-regulated alternator rated for continuous duty at 80° C temperature rise, as measured by the resistance method over a maximum ambient temperature of 40° C. The LIMA(r) MAC provides superior three-phase induction motor starting performance, capable of starting, across the line, 1 HP NEMA starting Code G squirrel cage induction motors per kW of its name plated rating.

LIMA(r) MAC frames are either cast aluminum or welded steel, with cast iron bearing brackets. LIMA(r) MAC generators are available in either a single-bearing configuration with a flex disc type coupling rigidly bolted to the alternator shaft, or as a two-bearing type with keyed shaft extension. The unit’s enclosure is fully guarded and meets the requirements of NEMA and IEC protective classification IP22.

The insulation system of both stationary and rotating windings is rated NEMA Class F or better, and is inorganic and non- hygroscopic. The main rotor is layer wound with thermosetting, 100% solids epoxy between each layer.

The 4-pole main revolving field construction consists of one-piece lamination. 360 and larger frame sizes incorporate full ammortisseur windings. The main stator is random wound and lashed at the end turns to provide superior mechanical strength. Excitation is provided by an integral rotating-current-transformer induction frequency converter. The phase wound exciter stator is directly inter-connected with the main stator, and incorporates two separate windings: a shunt winding and a series winding. No load excitation is provided by the shunt winding, while the series portion provides a load-compounding characteristic.

Voltage regulation is typically 4% from no load to full-rated load, at the rated operating temperature. The output voltage exhibits a “volts-per-hertz” characteristic throughout a minimum speed range of 60% to 125% of the unit’s rated synchronous speed to assure the proper performance of induction motor loads, while exhibiting electro-magnetic interference suppressed to commercial standards.

The load-compounding characteristics of the three phase LIMA(r) MAC generator is capable of supporting fault current equivalent to 500% (5 PU) of its full load rated current for 10 seconds to assure clearance of a fault condition without the use of external current transformers or other vulnerable external circuitry.

280 Frame generators have a side mounted split “clam shell” type connection box that rotates through 360° in 90° increments to allow egress of leads to the top, bottom, right or left. 360 and larger frames have a top-mounted, saddle-type connection box constructed to allow lead egress from the top or either side.

All certified performance and temperature rise test data are the result of actual testing of the same or duplicate units. Temperature rise data is the result of full load heat runs at rated voltage and frequency.
