What is a “model family” definition for three phase electric motors?
The use of families is intended to allow a range of very similar products to be covered by a single registration. Three phase electric motors registered for MEPS are a special case and some regulators will allow grouping of motors into “families” for the purposes of registration on the basis of motor output and number of poles (kW) or by frame size (to reduce costs for registrations of a whole series of motors that are registered together). This is only permitted for bulk registrations (typically more than 20 motors registered at the same time). Each motor kW/frame/pole combination is separately identified within the registration database. You can get more information on “families” in Attachment 3 of the administrative guidelines.
