High Efficiency Evaporator Fan Motors

Typically for commercial refrigeration evaporator fan motor applications ec motors are 66 efficient and psc motors are usually about 29 efficient.

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. Direct drive motors produce less noise and vibration than belt drive motors. Direct drive motors include condenser fan motors pedestal fan motors room air conditioner motors and unit heater motors. The end result after this efficiency upgrade is that the new evaporator fans save over 60 on electricity half the time over 90 during compressor off cycles.

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. These fans run twenty four hours a day. This is especially true when changing evaporator fan motors in coolers freezers. They mount directly to the drive shaft of hvac equipment which minimizes friction during operation and increases efficiency.

The ecm variable speed fan motors are used in condensers that have a modulating compressor. Historically shaded pole motors have been the most commonly used evaporator fan motors in commercial refrigeration equipment and beverage vending machines.
