Air Handling Applications
NovaTorque is a proud and active associate member of the Air Movement and Control Association.
NovaTorque motors are ideally suited for Air Handling applications, particularly applications that benefit from high efficiency over a very broad speed and load range.
In addition to their energy efficiency, NovaTorque motors are physically smaller than comparably powered induction motors, allowing for improved air flow in direct drive applications.
Examples of Variable Speed, Variable Torque Applications
Centrifugal Fans & Blowers
Electric motors driving fans and blowers in commercial and industrial HVAC applications typically run full-time and represent one of -- if not THE -- largest contributor to the end users’ power bills. Hence, producers of commercial and industrial fans and blowers are being driven by their customers to provide more energy-efficient systems.
Varying the speed of the motor dramatically improves the efficiency of the system and provides rapid payback on the investment. VFDs (variable frequency drives) have therefore been widely and increasingly adopted, opening the door to consideration of permanent magnet motors, such as NovaTorque’s, for further improvement in efficiency
To date, the largest obstacle to adoption of permanent magnet motors in HVAC air handling applications has been cost, primarily related to the cost of rare earth magnets. NovaTorque’s all-ferrite design provides permanent magnet motor performance at a first cost that is more comparable to an induction motor, yielding significant energy savings and producing a very attractive payback on the small first cost premium.
Frame size is also often a consideration. The smaller the motor is, the better the airflow around it is in a direct drive application. More airflow translates into cooler operating temperature, and, therefore, improved efficiency, longer life, or the ability to operate the motor above its rated horsepower. NovaTorque motors are typically one full frame size smaller than their induction motor competition.
