Scope

This part of GB/T 17948.1 specifies the test procedures for thermal evaluation and classification of insulation structures of loosely wound windings used or intended for use in AC or DC rotating motors. The test performance of the insulation structure to be evaluated is compared with the test performance of the reference insulation structure proven by operational experience. GB/T 17948.7-2016 describes the basic test principles for thermal resistance tests of rotating motor insulation structures. Unless otherwise specified in this part, the principles of GB/T 17948.7-2016 shall be followed in the execution of the tests.
