Drive of a rail locomotive using linear motors. Antrieb eines schienengebundenen Triebfahrzeuges mit Hilfe von Linearmotoren

Abstract

The purpose of the invention is to avoid the disadvantages of asynchronous linear motors, for example for need for reactive current for excitation, where driving on a normal section and driving on a branch line should be possible without losing the saving in weight on the inductor. According to the invention, the common inductor on a synchronous linear motor consists of 2 parallel packets of laminations surrounded by DC excitation windings and the secondary systems consists of unwound and spaced magnetic sections covering the two packets of laminations on the normal section. In the direction of thrust, their length extends nearly over the pole pitch of the multi-phase AC winding. According to the invetnion, this drive therefore consists of a synchronous linear motor combined into a double motor, with an external, rail shaped fixed secondary system, which has a multi-phase AC winding opposite it.
