Psc motor efficiency

The two technologies used in furnace and air handler blower motors are permanent split-capacitor ( PSC ) or induction motors an more recently, electronically commutated motors (ECMs), which are also known as brushless DC motors. ECMs can offer gains in efficiency , especially when their . Looking to switch to EC Motors ? The range of efficiency for PSCs is very broad , . The electrical output of the motor is not controllable and there are no speed variances to control.

One of the primary energy consumers in your heating system is the furnace blower motor.

The same holds true for the air conditioner blower located in the air handler.

Yet, when published efficiency ratings for new furnaces and air conditioners are computed in the laboratory, the efficiency of the blower . Utilizing high efficiency small motors offers the greatest power saving opportunity today as most of these currently operating motors have very low efficiency. Most small motors , commonly found in air handlers, air conditioners and refrigeration applications, are Permanent Split. They are typically used on fans, blowers, small pumps and gear motors.

Permanent Split Capacitor ( PSC ) motors are widely used when starting torque requirements are not too high and moderate electrical efficiency is needed. As energy costs increase the permanent split capacitor ( PSC ) motor , with energy efficiency in the range of to percent, became an attractive . ASHRAE – Fraction HVAC Motors. Small are PSC Class – not covered by new.

EC or Brushless DC Motors More Efficient for both variable speed . Size, weight, longevity and efficiency have all contributed to their success.

This article explores the benefits of these motors over the traditional PSC motor. Most commercially available ECPM motors are smaller than. As motor size increases, the efficiency -based energy savings potential of single-speed ECPMs decreases because PSC and three- phase induction motor efficiency in- creases.

However its operating characteristics are ideal for all fan type applications.

The motor may be produced for dual voltage and certain multi- speed uses, and can be operated from electronic voltage controllers (speed control). Price Fan Powered Terminal Units can be supplied with the latest motor technology: ECM – Electronically Commutated. The purpose was not only to demonstrate the ability of the high efficiency ECM motor technology to save large amounts of electrical energy in moving air in. The two CCHT houses were benchmarked (run with the normal permanent split capacitor ( PSC ) fan motors in both) to show that their operation was . Most of the single phase air conditioning applications today use per- manent split capacitor motors.

This paper shows the relative efficiency improvement obtainable in.

Versatile 4-way convertible design for upflow, downflow, horizontal left and horizontal right applications. Sturdy cabinet construction with 1. PSC motors as one makes trade-offs in motor stack height, capacitor size. Field-installed auxiliary electric heater kits provide exact heat for .
