DA METHOD FOR DETERMINING THE MOMENT OF STATIC FRICTION OF A COLLECTOR ELECTRIC MACHINE, which consists in connecting a constant voltage to the root of the machine under investigation, changes the magnitude of this voltage until the shaft of the machine under study starts rotating, fix this value and relieve the voltage from the casing, relieve this voltage and relieve the stress on the machine, measure the voltage and relieve the voltage of the machine under test. So that, in order to improve the accuracy of determining the moment of friction, the shaft of the machine under investigation is additionally driven into rotation with a constant frequency, is measured. The EMF, the windings of the crust of the machine under investigation, and the moment of static friction are determined by the formula E iMcikiC "G7T - EDS winding core where E U is the maximum voltage value, cf. corresponding to the moment on, the beginning of rotation of the shaft; n = h = rotational shaft rotation; fg R is the sensor resistance in the winding of the core.
