MTE® | dV/dt Motor Protection Filters Canada
Safeguard motor winding insulation, eliminate destructive voltage spikes, and prevent premature motor failure caused by variable frequency drive (VFD) output with dV/dt motor protection filters from MTE Corporation in Canada. Engineered to address high-speed pulse-width modulation (PWM) switching hazards, MTE dV/dt filters attenuate rapid voltage rise times ($dV/dt$) and damp reflective wave peak voltages before they reach motor terminals. Designed and tested to satisfy strict CSA, UL, and IEC safety standards, MTE dV/dt filters extend motor service life across long cable lead lengths in harsh industrial environments.
Our inventory features authentic MTE dV/dt motor protection filters, including advanced filter lines optimized for VFD lead lengths up to 1,000 feet. Featuring robust magnetics and specialized damping networks, MTE dV/dt filters reduce peak terminal voltages to safe levels below NEMA MG1 Part 31 standards ($1600\text{V}$), control motor operating temperatures, minimize bearing fluting currents, and eliminate line-to-line voltage ringing in automated processing, pumping, and HVAC drive systems.
