モータ。[Claim for Utility Model Registration] A pair of magnetic cores with excitation coils wound on both sides of a permanent magnet, a stator with a four-phase magnetic pole tooth row arranged on the magnetic core, and a stator capable of reciprocating motion on the stator. A linear pulse motor comprising a mover which is arranged and has a magnetic pole tooth row opposite to the magnetic pole tooth row on its lower surface,
1. A linear pulse motor for driving a magnetic head, characterized in that the mover is provided with a forwardly protruding shielding part at least at the front part in the moving direction, and a magnetic head mounting surface is formed on the upper surface of the shielding part. 2. A linear pulse motor for driving a magnetic head according to claim 1, wherein the shielding portion is integrally formed with the movable element and is made of a magnetic material constituting a closed magnetic path for the leakage magnetic flux of the stator. 2. A linear pulse motor for driving a magnetic head according to claim 1, wherein the shielding part is constituted by a separate member from the moving element and is magnetically linked to the moving element.
