Consider cabling, size and windings in order to make the right choice.
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.
In some instances, operating a motor beyond the base pole speed is possible and offers system benefits if the design is carefully examined
