    • The invention relates to a layered carbon brush (10) having a carbon body (11) which has two carbon layers separated from each other by an insulation layer and arranged in combination and which form a contact surface in a contact section (18) for connecting to a commutator (23) of an electrical motor with the end faces thereof opposite a connecting conductor side of the carbon body, wherein the contact section has a contact cross-section which has a width a, axis-parallel to a commutator axis (28), and a height t, tangential to the circumference of the commutator, wherein at a height t of greater than or equal to 4.5 mm and smaller than 5.5 mm, the width a equals at least 2.8 times the height t, or wherein at a width a of greater than or equal to 12.5 mm and smaller than 13.5 mm, the height t equals 0.25 times to 0.35 times the width a, and at a width a of greater than or equal to 13.5 mm and smaller than or equal to 15 mm, the height t equals 0.23 times to 0.32 times the width a.
    • 本发明涉及一种层碳刷(10),其包括通过绝缘层彼此分开并布置在所述复合碳层,其与碳体相对的端的其一个端子导体的部分,在接触部分(18)面对具有两个碳体(11)具有一个接触表面,用于抵靠邻接 电动马达形成,其中,所述接触部具有接触部的换向器(23),所述轴线平行于一个换向器(28)具有一宽度和切向于换向器吨的高度的圆周上,在高度t表示大于或等于4.5毫米, 小于5.5毫米,宽度的高度T的至少2.8倍,或其中,在宽度的0.25倍大于或等于12.5毫米,小于13.5毫米,高度T为0的 是35倍的宽度,在一个宽度比大于或等于13.5毫米,小于或等于15毫米,0.23倍的高度0.32吨 是倍的宽度。
