LAVERGNE, Tenn. - A.O. Smith Electrical Products Co. announced that it has expanded its line of 4-in-1® multiple-horsepower motors to now include new 1/2-horsepower ratings. The company said the new 4-in-1 motors replace hundreds of the most popular 1/2-1/5 hp, 208-230 and 460 volt, 825 or 1,075 rpm residential and commercial condenser fan motors.

The company said the expanded line includes three new 1/2-horsepower ratings for the deluxe 4-in-1 HeatMaster® motor series for use in high ambient temperature applications. With this new horsepower option, the 4-in-1 line now reduces the need to stock four different models for replacement applications.

The HeatMaster line of motors is built with UL and CSA approved Class F insulation, which enables these motors to meet 70°C (158°F) 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 the toughest applications, said the company.

A.O. Smith’s 4-in-1 motors may be mounted by bellyband, thru-bolts, or shell holes. The totally enclosed construction of the motor allows for all-angle mounting and they are designed with a water-resistant reversing plug for quick rotation change.

These 48-frame condenser fan motors are installed with one connection, eliminating complicated wiring diagrams and the need to switch capacitors, said the company, making installation much easier for contractors.
