• Popular JuggerNaut® Lineup Now Includes a New 1.5HP 850-RPM Motor

    February 13, 2008

    Tipp City, Ohio – A. O. Smith Electrical Products Company has introduced a new addition
    to its line of inverter-duty condenser fan replacement motors for commercial air conditioning and
    refrigeration markets. Stock number H1054 now joins the original four JuggerNaut® ratings to cover
    a greater range of applications.
    Many retailers are now retrofitting inverters to their existing air conditioning and refrigeration
    equipment to reduce the motors' energy consumption. They are discovering, however, that existing
    OEM motors cannot withstand the strain that the inverter places on the motors, resulting in premature
    The JuggerNaut design is the first in the industry to hold up to the rigorous demands
    inverters place on motors.
    • Inverter Duty - Corona free with conductive bearing grease for reliable use with today’s
    • Class F Insulation - for 70°C (158°F) maximum ambient conditions;
    • VCM™ – A. O. Smith's own unique quick-connect “Voltage Change Module”;
    • Removable Rigid Base - Easy to remove 56H rigid base provides for either rigid base or
    belly band mounting.
    Thepopular JuggerNaut® lineup now includes a new 1.5HP 850-RPM motor - 2
    Designed with a UL & CSA approved non-hygroscopic Class F insulation system, the
    JuggerNaut achieves superior dielectric strength for long thermal life. While most commercial
    condenser fan replacement motors have Class B insulation systems rated for 60°C (140°F) ambient,
    JuggerNaut motors are rated for 70°C (158°F) max ambient. This extra temperature range means that
    each JuggerNaut motor is built to withstand the extreme temperature conditions that are often found
    in commercial roof-top applications.
    The use of conductive bearing grease shields the bearings from arcing damage caused by
    inverter usage, and each JuggerNaut motor is tested on a proprietary CIV tester. This testing
    equipment employs a unique procedure to detect and measure corona for every JuggerNaut motor
    before the motor leaves the factory.
    These energy-efficient, three phase motors are capable of reversible rotation with A. O.
    Smith’s own Voltage Change Module (VCM). Changing between 230 and 460 volt connections is
    now quick and easy.
    Each JuggerNaut motor incorporates a special removable 56H rigid base to add flexibility in
    mounting options, allowing the service contractor to have the correct motor on hand and reduce
    inventory carrying costs.
    JuggerNaut replacement motors are available in five ratings, 1 HP, 1-1/2 HP, 2 HP at 1140-
    RPM, as well as 1 HP and 1.5HP at 850-RPM.
    “This new line of JuggerNaut inverter duty, high ambient rated motors is something the
    HAC/R replacement market has long awaited,” Warren Doney, HVAC market manager
    A. O. Smith Electrical Products Company, said.
