    Electric Motor Buying Guide (Video)

    How do you choose an electric motor? Craig Hartman, gives you the introduction to electric motor buying guide.
  3. Shaft Grounding Rings - The Necessary Accessory for Your Motor and VFD

    Shaft Grounding Rings - The Necessary Accessory for Your Motor and VFD

    Motors operating from a VFD are more susceptible to bearing failure. Shaft grounding rings help dissipate voltage arcs that lead to motor bearing failure.
  4. High Voltage Spike (dV/dt) and Motor Protection Methods

    High Voltage Spike (dV/dt) and Motor Protection Methods

    Large distances between a motor and a VFD can cause high voltage spikes. High voltage spikes can damage motors and lead to early failure.
  5. Bearing Currents

    Motor bearings have a higher failure rate when the motor is run with a VFD. AEGIS shaft grounding rings mitigate shaft voltage spikes and improve motor bearing lifespan.
