The universal motor (1) has a brush (2), which is arranged in a brush holder (3), and a bearing bracket (5), on which the brush holder is arranged. The brush holder is arranged in an electrically isolating housing (4), which is arranged on the bearing bracket. A heat dissipating element (7) is arranged between the bearing bracket and the housing or between the housing and the brush holder. The cavities between the housing and the brush holder are filled with a grouting material, particularly a heat-conductive plastic material.
