NS Motors 1

[mcdm]

Hi all I overheard two electrical winders discussing NS motors when I asked them what the NS meant they simply said they were named NS after the person who designed them.
Who or what is NS?

Suggestion: It might also mean Non-Standard Motors.

The "N-S motor" was a trade named used by Lawrence Scott and Electromotors, Norwich, UK for their variable speed commutator ac motors. These machines, built before the widespread availability of variable frequency inverters, were widely used for pumping applications in the UK and abroad.
