ABSTRACT:
A movable magnet type linear motor with a mover heat-dissipating assembly includes a mover having a housing receiving therein a coil seat for holding a coil, openings being formed at two opposite ends of the housing, end covers being attached to the openings and having central holes so as to allow an inner stator to pass through the holes, wherein a plurality of heat dissipating channels are provided between the coil seat and the housing while the end covers have plural heat dissipating holes corresponding to the heat dissipating channels so that external cool air is allowed to enter the housing through the heat dissipating holes and the heat dissipating channels, thereby cooling the mover.
