This higher pressure increases the torque on the motor. When the microprocessor senses increased torque, it automatically increases the speed of the motor. A faster motor creates more airflow to make sure that CFM stays steady despite the resistance in the system from conditions like clogged filter or a hard-working evaporator. More airflow also reduces static pressure, which reduces torque. At the same time, increased airflow also provides the additional oomph of airflow that the system needs to provide additional cooling or heating capacity during high demand times for the system.
The control board dipswitch settings usually set in the field need to be set up properly for proper seasonal operation. The energy savings come into play when demand and static pressure decreases. When it is not needed at full speed, the motor can slow down, which uses far less energy. A motor running at full speed uses nearly 8 times the energy of a motor running at half speed. So any time you can slow it down, even a little, saves you big bucks. This high pressure increases the torque on the motor.

Hey, I am Rajkumar. The Man Behind MechanicalJungle. I started this site to spread knowledge about Mechnical Engineering. An ECM motor is also quieter than conventional inefficient motors and has a longer design life.
Also, these motors require less maintenance. So, an electronically commutated motor provides the flexibility and technology to ensure quiet, smooth, and efficient delivery of suitable airflow at all time. And in terms of features, as these motors are controlled by software, they allow customers to easily optimize as well as integrate the motor, controller, and fan with the furnace.
They also have features like volume control, data communications, and variable speed, etc. While they offer many benefits, you have to ensure that your contractors use them safely. It is likely that your HVAC company is a local business, and typically, customers search for local contractors. This is why you should leverage Google My Business to grow your business.

Some disadvantages of these ECM motors are as follows: The friction of the brushes that slide along the rotating commutator segments can cause power losses.
These losses can be significant, especially in low power motors. Did you know that the soft brush material tends to wear down because of friction? The microprocessor uses a closed-loop feedback mechanism to more precisely control the magnetic fields, minimizing the eddy currents and losses used by traditional mechanically commutated motors. This also allows a brushless motor to be used, therefore reducing points of physical contact within the moving components of the motor and making them more durable.
Permanent split capacitor PSC motors , often used in conjunction with electronic SCR motors, are somewhat inefficient when used in air control systems. This is because the fan motor noise requires the motor to run at less than a full load. When turned down, PSC efficiency suffers and falls in the range of 12 to 45 percent. ECMs, on the other hand, maintain a high level 65 to 75 percent of efficiency at a variety of speeds. As a result, ECMs are more energy-efficient and can reduce operating costs.
Additionally, ECMs are not prone to overheating and do not require additional measures to offset the generation of heat, as PSCs often do. ECMs are also relatively low-maintenance; the use of true ball bearings reduces the need for oiling, and varied start-up speeds reduce stress on mounting hardware. The operating range is significant enough to enable one ECM to replace two induction-style models, which simplifies the replacement, maintenance, and installation processes, and minimizes product choices.
