The outer heat radiating housing covers the body and is integrally jointed to the body. The outer heat radiating housing is defined with a plurality of passages. When the current is supplied to the coils of the body, the body will be driven, the heat energy produced by the body can be conducted to the outer heat radiating housing sufficiently. In addition, after the cooling liquid is conducted to the passages, the heat radiating effect of the mover can be improved.

Abstract: A position feedback device for a linear motor comprises three linearly-arranged Hall sensors. The three Hall sensors are connected to a mover, respectively. The direction in which the Hall sensor in the middle of the three Hall sensors is reverse to the direction in which the other two Hall sensors of the three Hall sensors are connected, so that the arrangement distance of the three Hall sensors can be reduced, and the size of the position feedback device can be reduced.

Abstract: A modular mover for a linear motor comprises: a plurality of iron cores including internal coils and a connecting member. These iron cores have the same size and juxtaposed in the same direction on the connecting member. By supplying the coils with a current, each iron core can cooperate with a stator by generating magnetism. Since these iron cores have the same size, it just needs to produce a single sized iron cores. The mover output capability can be changed by changing a number of the iron cores so as to save the cost in producing different sized iron cores.
