This document presents the results obtained from the application of the law of Lens to correctly identify the polarity of the windings in a three-phase motor with 6 exposed terminals, when the corresponding labeling is not in any situation; Prior to identifying the polarity, it should be considered to have the pairs of the three windings located. For the polarity, it is proposed to feed with a voltage of 12 Vrms to one of the windings, which are identified randomly as W1 and W2, where W1 is connected to the voltage phase of 12 Vrms of the signal and W2 to the voltage reference to 0V; by means of voltage induction and considering the law of Lens, the remaining 4 terminals can be identified and labeled as V1, V2, U1 and U2. For this process a microcontroller and control elements with low cost are used.

Bill Kaplin and Barbara Lee let their readers know up front - on the book's cover in fact - that "A Legal Guide for Student Affairs Professionals" has been adapted from their highly regarded third edition of "The Law of Higher Education" [LHE3](1995) ("the big red book," as my students refer to it). The authors have included material already presented in LHE3 but have completely reorganized, updated, and edited the earlier work.
