A new line of invertor-duty condenser fan replacement motors is available for commercial air-conditioning and refrigeration markets. JuggerNaut can hold up to the rigorous demands invertors place on motors. 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 allows JuggerNaut motors to withstand the extreme temperature conditions often found in commercial rooftop applications. The use of conductive bearing grease shields the bearings from arcing damage caused by invertor usage. The energy-efficient, three-phase motors are capable of reversible rotation, and, with the company’s own voltage change module, changing between 230- and 460-V 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 costs. The replacement motors are available in four ratings: 1 hp, 1½ hp, 2 hp at 1140 rpm, and also 1 hp at 850 rpm.
