A STUDY OF UNEVEN WEAR IN COMMUTATORS

Mathematical study using a diagrammatical test model of the phenomenon. The effects of mechanical wear that tends to develop in the commutator surface, which corresponds to the variations and is due to strains in the brushes, is represented by a Fourier series based on the angular velocity of the motor. The electric wear profile is also described. The author reaches conclusions about ways to lengthen commutator life.
