microNexus™ Motor Protection Filter
Complete motor protection in
a micro-sized package.
MTE’s microNexus filter takes the proven performance of our award-winning SineWave Nexus and shrinks it down into a space-saving solution that integrates into any micro drive application. The microNexus not only eliminates voltage spikes generated by Variable Frequency Drives (VFDs), and reflective waves that cause motor windings and cables to fail, but it also virtually eliminates common mode voltage which causes motor bearing failures, cable degradation, and VFD faults. By filtering out damaging common mode voltage, motor bearings are never subject to harmful voltages that cause damaging pitting, frosting, or fluting of bearings, all which lead to motor failure.
microNexus eliminates the need for common mode chokes and inductive absorbers that only temporarily extend motor life. Additionally, there’s no need for shaft grounding rings which require ongoing maintenance and replacement. With our microNexus, you have a complete, compact electrical solution for big electrical problems.
