Abstract:
A linear motor includes an armature with two magnetic poles arranged in the Z direction, and winding wires wound around the two magnetic poles, respectively, and a mover with a permanent magnet, which moves relative to the armature in the Z direction. A first auxiliary magnetic pole is disposed between the two magnetic poles, and a bridge is disposed between the first auxiliary magnetic pole and the magnetic pole. The two winding wires are electrically coupled.
