MTE Corp. released its Matrix Air EC Motor Filter that is designed to mitigate harmonics that are produced by electronically commutated motors (ECMs). This new solution is optimized for HVACR and data center cooling applications and can also be used anywhere ECMs are installed, such as conveyance systems, variable refrigeration flow (VRF) equipment, and refrigerated displays.

ECMs combine the benefits of DC electric motors with integrated drives and are primarily used to control the speed of fans, such as those found in data center fan walls and air-handling units. However, because ECMs emulate variable frequency drives (VFDs), they produce damaging harmonics that degrade and “pollute” lineside power quality, which causes nuisance tripping, equipment to overheat, and problems with electrical utilities.
