  • Linear motor armature and linear motor using the same
    Patent number: 7446439
    Abstract: It is an object to provide a linear motor armature which can simplify the motor structure and reduce the size while reducing the deformations of the board, the can and the frame, and a linear motor using that armature. The linear motor armature comprises an armature coil (11) fixed on the two side faces of a board (12), and a sealed body including a can (2) and a frame (3) and disposed to cover the armature coil (11), and a coolant is fed around the armature coil (11) to cool the same. The armature coil (11) is adhered and fixed to the board (12) and is assembled with the frame (3). After this, a brace (9) is arranged between the can (2) and the frame (3), and the can (2) and the brace (9), and the frame (3) and the brace (9) are individually jointed to each other by welding them.
