The Impact Of Installing Harmonic Filters On Extending Motor Lifespan

Harmonics in power supply networks cause distortion of voltage and current waveforms, exacerbating thermal stress and mechanical wear in motors and related devices, potentially shortening equipment lifespan over long-term operation. harmonic filtering equipment can reduce waveform distortion caused by power grid harmonics and its impact on equipment, thereby having a positive effect on the operating status of the motor.

Motors often operate in parallel with frequency converters and other nonlinear loads, which generate current harmonics, causing the power supply waveform to deviate from the ideal sinusoidal shape. The active harmonic filter cost can intervene in power lines to suppress harmonic frequencies of different levels, making the current and voltage closer to the standard waveform, and reducing the burden of heat accumulation and magnetic loss effect on motor windings and bearings.
