Abstract

Various evaporator fan motor technologies used in commercial refrigeration are discussed. Data from a DOE-sponsored evaporator fan motor laboratory and field demonstration project are presented. Historically, shaded-pole, permanent split capacitor (PSC), and electronically commutated (EC) motors have been used as evaporator fan motors in commercial refrigeration equipment. A permanent magnet synchronous (PMS) AC motor that can directly use grid-supplied AC current without the need to rectify to DC has recently been commercialized. It was found that PMS motors consume 79% less power and draw 82% less current than shaded pole motors, and 34% less power and 49% less current than EC motors. PMS motors exhibit a power factor of 0.82, which is 40% greater than that of existing evaporator fan motors. The measured data is extrapolated to project the economic and environmental benefits from upgrading the installed base of commercial refrigeration evaporator fan motors to PMS motors.
