Both are more efficient than the typical PSC motor, with ECM motors commonly being about 80% efficient and PSC being about 60%. ... An X13 motor is programmed to produce a set motor torque based on which input it is receiving 24v.
What is the difference between a PSC motor and an ECM motor?
The Difference Between an ECM Motor & a PSC Motor
The big difference between the two models is that the PSC motor has one speed: full speed . ... The ECM model is a variable speed unit that will adjust the airflow to optimal levels based on the desired temperature of the home.
What is the difference between X13 and ECM?
The X13TM adjusts its speed ( High, Medium High, Medium, Medium Low, Low ) based on changes to static pressure by only monitoring changes in torque. This ‘standard ECM' motor is much more efficient than PSC motors, but less efficient when compared to ECM variable speed motors.
Which is better ECM or PSC motor?
ECM technology is based on a direct current (DC) design that is more efficient and it runs cooler than AC PSC motors. They are, in fact, approximately 80% efficient compared to the 60% efficiency rating of PSC designs. ... When it comes to disadvantages, ECM variable-speed motors come at a premium cost.
What are the advantages of a ECM over a PSC motor?
ECM motor (electronically commuted motor) – Runs at a variable speed. This provides several benefits, including energy savings, lower need for maintenance , improved comfort and better airflow and indoor air quality.
Are ECM motors worth it?
ECM motors are expected to keep homeowners more comfortable, too . First, they provide more efficient airflow. ... Some homeowners may opt for repairing an old furnace, but it can be a costly decision when compared to the energy savings of replacing it with an energy efficient furnace.
How efficient is an ECM motor?
The ECM motor has a minimum efficiency of 70% throughout its entire operating range. Conventional induction motors become less efficient at the reduced speeds that are typically selected for fan powered applications.
Is X13 an ECM motor?
Both variable speed and X13 motors are ECM or “electronically commutated motors ,” which means that the DC power that drives them is electronically switched from positive to negative to spin the motor. ... The primary difference is the type of inputs to the motor control.
Is ECM the same as variable speed?
The term “Variable Speed” actually refers to the blower motor inside the furnace or air handler. It's an Electronically commutated motor , or (ECM). ... The initial cost of a furnace with an ECM will be higher than a traditional furnace, but the typical payback on a variable speed furnace is just 4 to 5 years.
What does ECM stand for in motors?
Electronically commutated motors (ECM) represent an advance in blower motor efficiency that saves substantial energy and improves aspects of overall system performance. ECMs are brushless motors developed by General Electric, which owns the trademark on the name.
Are ECM motors quieter?
ECM motors are very high efficiency (65% to 80%) electric motors. ... ECM motors are also quieter than traditional inefficient motors , have longer design life, and require less maintenance.
Why do ECM motors fail?
Some older ECM motors will overheat and even fail when constantly running in over-amped conditions . Newer models are designed to drop airflow but time will tell on how well they will hold up. Other consequences of high static installations include noise at the registers from higher air velocities.
Do ECM motors use capacitors?
One of the characteristics of the ECM is that they do not require adding an external run or start capacitor . But a run capacitor may still be needed for the compressor.
How much does an ECM motor cost?
| Belt $5 – $100 | Housing $100 – $300 | Capacitor $150 – $450 | ECM Motor Module $230 – $830 |
