A PSC motor is a commonly used motor that runs at either single or variable speeds, while an EC motor is much more energy-efficient and features an internal smart board offering better motor control. Using EC motors holds three clear advantages over the use of PSC motors. Advantages of EC ...
ECM (electronically commutated motor) motors are one of the advancements the HVAC industry has made in furnaces within the last few years. One of the goals of HVAC research is to find ways to increase the energy efficiency of systems to benefit homeowners, businessowners, and the environment as...
The study reported herein is to experimentally evaluate and compare the performance of blowers driven by permanent split capacitor (PSC) motors and electronically commutated motors (ECMs) in residential non-weatherized, non-condensing gas furnaces. As a first step, twelve units from four manufacturers...
The EC motors are torque sensitive. The EC motor on the dirty coil required a higher RPM to get the motor to perform according to its program, i.e. 1580 RPMs. The motor worked harder to overcome the dirty coil. To maintain constant RPM, the EC motor senses the resistance and automatical...
ECM Control:Cirrus-ECM In recent years, the availability of ECM motors has greatly increased. These are basically DC motors with built-in transformers allowing them to be powered from the AC line. As a result, these motors are the most energy efficient and easiest (inexpensive and accurate) ...
