An electromagnetic dog clutch is disclosed to solve the technical problem in conventional electromagnetic dog clutches that the friction is easy to occur between a bearing seat and an end cap of a movable gear sleeve. The electromagnetic dog clutch comprises a movable gear sleeve () and a fixed gear sleeve () that mesh with each other for transmission. A first end cap () is provided on an outer side of the movable gear sleeve (), a bearing () is provided on an outer circumference of the movable gear sleeve (), the bearing () is embedded in a bearing seat (), a rear end of the bearing seat () is provided with a positioning surface, and a front end of the first end cap () is a vertical plane that matches the positioning surface of the bearing seat (). The front end of the first end cap () is provided with a positioning pin (), the rear end of the bearing seat () is provided with a positioning hole to cooperate with the positioning pin (), and the positioning pin () is inserted into the positioning hole to limit the bearing seat () and the first end cap () so that they can move in an axial direction relative to each other but cannot rotate relative to each other, thereby preventing the occurrence of friction between them.
