High Efficiency Evaporator Fan Motors

Historically shaded pole motors have been the most commonly used evaporator fan motors in commercial refrigeration equipment and beverage vending machines.

High efficiency evaporator fan motors.

Fasco d7908 5 6 inch condenser fan motor 1 3 hp 208 230 volts 1075 rpm 1 speed 2 6 amps totally enclosed reversible rotation ball bearing 4 2 out of 5 stars 76 65 95 65. The ecm variable speed fan motors are used in condensers that have a modulating compressor. These fans run twenty four hours a day. Typically for commercial refrigeration evaporator fan motor applications ec motors are 66 efficient and psc motors are usually about 29 efficient.

This is especially true when changing evaporator fan motors in coolers freezers. Direct drive motors include condenser fan motors pedestal fan motors room air conditioner motors and unit heater motors. Higher efficiency evaporator fan motors reduce energy consumption by requiring less electrical power to generate the same motor shaft output power nci pnnl 2011. Direct drive motors produce less noise and vibration than belt drive motors.

They mount directly to the drive shaft of hvac equipment which minimizes friction during operation and increases efficiency. â a new motor technology a type of permanent magnet synchronous ac motor that can directly use grid supplied ac current without the need to rectify to dc has recently been commercialized.
