Consider these methods to help protect systems from high-frequency current damage.
Motors
Motors are the most common source of power used by pumping systems. This technology is heavily regulated. Pumps by themselves are not variable speed, an option that many systems need to operate with peaks and ebbs during the run cycle, such as power generation. The addition of a variable frequency drive (VFD) gives it that capability.
Understand these concepts before starting squirrel cage induction motors.
Harmful common mode shaft voltages can damage motor bearings and cause premature machine failure.
Separation can improve delivery time and allow exact replacement.
Furnace blower motor design transformation was fueled by new end user and government standards.
This technology can help reduce blockages, detect damaged equipment and avoid dry runs, thus reducing motor stress.
Understand accessories, sizing, electrical performance and color.
What makes motors standard and what could make them special?
Most pumps are driven by AC induction motors.
