VFD Motor Principle & Harmonic Mitigation

VFD PWM output has steep dv/dt and rich harmonics; standard motors face turn-to-turn stress, bearing EDM and extra heating. VFD motors add reinforced insulation, corona-resistant wire and insulated/grounded bearings.

Harmonics raise copper/iron loss and cause torque ripple. Output reactors, dv/dt or sine filters curb voltage spikes and protect insulation and bearings.

XIMA YVFE/YJTKK/YJTG are optimized in insulation, bearings and cooling for mainstream VFDs, serving fan/pump savings and precise rolling-mill control.
