Electric motor insulation classes
WebJan 6, 2010 · Insulation "Class" has to do with temperature rise, not voltage spikes. VFD controlled motors should have higher VOLTAGE ratings on the winding insulation, but that is NOT reflected in the class rating. Class F is a really good idea, but not an absolute. If for instance your pumps are in a well ventilated space, Class B would probably be fine.
