Introduction
In modern industry, electric motors driven by variable frequency drives (VFDs) have become the standard for energy efficiency and process control. These drives rely on pulse width modulation (PWM) to regulate motor speed and torque, aiming on current signals that approximate a sine wave. While highly effective for control, PWM introduces high-frequency transients that can compromise motor reliability if left unchecked.
