Abstract

A spring device for brush holders of rotating electrical machines, comprising: a spiral spring whose inner end is fixed to a fixed axial member of said brush holder; an additional spring having one of its ends fixed to the outer end of said spiral spring, in such a way that the horizontal component of the force of pressure of said spiral spring on a brush is substantially annulled by a horizontal component of the force of said additional spring on said brush in all of the positions thereof, while the other end is fixed to a plate member by means of which the pressure force of said spiral spring and of said spring is exerted on said brush. Said additional spring. (Machine-translation by Google Translate, not legally binding)
