A magnetizable U-shaped core is surrounded by an energized winding so that stray flux is produced at the core ends. A rotary wheel has a circular recess in the region of the core ends in which alternate magnetizable and non-magnetizable parts are fixedly secured so that during rotation of the wheel,...

Zusammenfassung: | A magnetizable U-shaped core is surrounded by an energized winding so that stray flux is produced at the core ends. A rotary wheel has a circular recess in the region of the core ends in which alternate magnetizable and non-magnetizable parts are fixedly secured so that during rotation of the wheel, the flux passed alternately by said magnetizable and non-magnetizable parts is varied so that pulses are generated in the winding. |
