The line of 4-in-1® multiple-hp motors has expanded to include motors with 1/2-hp ratings. The line of condenser fan motors now includes three 1/2-hp ratings for the 4-in-1 HeatMaster® motor series for use in high ambient temperature applications. According to the manufacturer, the new 4-in-1 motors replace hundreds of 1/2 - 1/5-hp, 208-230 and 460 V, 825 or 1,075 rpm residential and commercial condenser fan motors. The HeatMaster line of motors is built with UL- and CSA-approved Class F insulation, which enables the motors to meet 158°F (70°C) maximum ambient temperatures. In addition, the ultra high-torque designs and the use of double sealed ball bearings allow the 4-in-1 HeatMaster motors to perform in even the toughest applications, says the company. The motors may be mounted by bellyband, through-bolts, or shell holes; and the totally enclosed construction of the motor allows for all-angle mounting and are designed with a water-resistant reversing plug for quick rotation change.
