description The utility model relates to a motor component and in particular to a bearing cap at the commutator end of a DC traction motor for narrow gauge locomotives, which is contrived to mount a speed sensor on a DC traction motor for narrow gauge locomotives, thereby allowing speed measurement on the DC traction motor for narrow gauge locomotives. The bearing cap has an integrated disc-shaped cap body being provided peripherally with mounting holes to couple a unit seat; the counter boreholes are provided at the inboard end face of the cap body to house a speed-measuring gear; a surface is milled on the cap cylinder to arrange speed-measuring holes in connection with the counter boreholes at the inboard end face of the cap body and screw holes to secure the speed sensor. The bearing cap is contrived not only to house the speed-measuring gear and secure the speed sensor, but also provide the conventional protection for the bearing, which reduces the weight, saves costs and expands functions while maintaining the same
