Abstract:
1. A linear motor air-cooling structure comprising: at least one elongated stator having an elongated bed section and multiple magnetic sections sequentially arranged along a length of the bed section and fixedly disposed on one face of the bed section; a mover positioned in adjacency to one side of the bed section, under the action of magnetic fields created by the adjacent magnetic sections, the mover being reciprocally movable along the length of the bed section; and at least one cooling section having at least one main flow way and multiple bypass flow ways in communication with the main flow way, whereby the air flowing within the main flow way can be distributed to the respective bypass flow ways to flow out from the bypass flow ways so as to form airflow between the stator and the mover, the air-cooling structure being characterized in that the cooling section has a main body attached to one side of the stator along the length thereof, the main flow way and the bypass flow ways being disposed on the main body, each bypass flow way having an air outlet formed on the main body, the air outlet being directed to the mover in a direction away from the bed section; wherein the main body includes a substrate and a cover board attached and connected to one face of the substrate, the main flow way and the bypass flow ways being formed between the substrate and the cover board.
