Importance of Shaft Grounding for VFD Motors: A Comprehensive Analysis Variable Frequency Drives improve motor efficiency and control but can generate shaft voltages that lead to bearing damage through electrical discharge machining. Effective shaft grounding is required to redirect these harmful currents and protect motor components. Aaki’s Motor Shaft Grounding Module (MSGM) provides a reliable solution by routing shaft voltages safely to ground. With durable construction, easy installation, and Brush Life Window™ technology, MSGMs extend motor life, reduce downtime, and lower maintenance costs in VFD-driven applications.
