SA-96-07-2 -- High-Efficiency Refrigeration Fan Motors PDF

Points out that refrigeration is one of the largest consumers of electrical power in the USA. Application of new technology systems includes higher efficiency condenser and evaporator motors and fans to provide the refrigeration appliance industry with lower energy cost alternatives. Describes a brushless permanent magnet motor developed with low cost manufacturing assembly features, high efficiency fan blades and versatility for both condenser and evaporator applications. The compact motor design includes high efficiency, low cost electronics in a small, streamlined plastic motor housing. Maintains that in residential refrigeration, replacing the condenser and evaporator motors currently used with the new motor can reduce input power by 9% and reduce input current by 20%. In commercial refrigeration with its typical high-duty cycles the energy savings can be substantial.
