<p>An armature is displaceable relative to the core with a defined pole. Part of the core is surrounded by an excitation coil for magnetic flux flow through the pole on current supply. Between the pole surface and the armature is an air gap in the direction of the relative movement between the armature and core. A reverse flux air gap extends at an orthogonal direction to the relative movement between the core and armature (22). - The core carries a further coil (24) for a force flux through the pole (21) in the same direction as the excitation coil (25). For the force flux, generated by the additional coil, is provided another reverse flux air gap, also extended in an orthogonal direction to that of the relative movement between the core and armature.</p> |
