Abstract
The invention relates to a short stroke linear motor. In order to improve the dynamics of such a short stroke linear motor, the primary part () of the motor is provided with a single-strand winding. The primary part () and the secondary part () have essentially the same pole pitch (tZ=tM). In this way, a very high motor torque is produced in a limited range of displacement. In order to be able to reach a plurality of working positions without an inactive intermediate position, a short stroke linear motor having a double-strand winding is additionally provided, both strands being operated at a phase difference of <90°. The pole pitch of the primary part and the secondary part are again essentially the same.
