Abstract
Brush for electric motors obtained by compression of an electrically conductive powder containing one end of an electrical conductor so as simultaneously to allow the formation of the brush and the mechanical fixing of said electrical conductor, and characterized in that the density of at least a portion of the compressed powder in contact with the end of the immersed electrical conductor is higher than the mean density of the compressed powder so as to improve the strength of said mechanical fixing when said brush is subjected to vibrations.
