ABSTRACT:
Stepping motor including a runner (2) and at least one stator (4) relative to which the runner is movably mounted. The stator has at least two mutually parallel magnetizing elements (6,8,10) each with a groove-like space (19) extending in the travelling direction of the runner, pole tooth rows (12) being formed on the inside of the defining side walls of said space. The runner (2) carries an armature element (18) in each groove-like space with tooth rows (20) arranged along the pole tooth rows (12) of the magnetizing element such as to close magnetic flux paths in coaction with the armature element tooth rows, said paths extending via said side walls transverse the travelling direction of the runner (2). The parallel armature elements (18) are carried by a common carrying body (16) of non-magnetic material.
