Abstract

The runner rail of the linear motor is made of copper or aluminium, is rigidly fixed to the to-and-fro moving implement which is touches, or forms part of it. The rail has two stator coils positioned one behind the other and alternately switched on and off by means of a control switch and timer. The control stage can be induced by a time impulse generator and a position-indicator. The stator coil is divided into two part-coils by a centre point. A phase-changer capacitor is positioned in the supply voltage for connection to a single-phase alternating current. A direct-voltage alternating current transformer is for connection to a direct voltage source.
