Unlike traditional motors that operate only at the fixed power grid frequency (usually 50 Hz or 60 Hz), a VFD generates an adjustable-frequency output, allowing the motor to run faster, slower, or follow a controlled acceleration and deceleration process. In simple terms, a VFD works by converting incoming AC power into DC power, smoothing the DC voltage through the DC bus, and then converting it back into a controlled AC output using high-speed electronic switching technology. This conversion process allows precise control of motor operation and [&hellip;]"}
