Definitions
- the inductive transformer is designed as a rotary transformer. It consists of two coils 1, 2, each with an annular core 3, 4, one of which - in the exemplary embodiment, the core 3 - is rotatably supported about an axis Z.
- the two cores 3, 4 can have an L-shaped cross section.
- the leg of the L of the core 3 facing the core 4 is provided with a contour 5, here a bevel.
- a magnetic field-sensitive sensor 6 is arranged on the core 4, which acts as a Hall sensor, magnetoresistive sensor or the like. can be trained.
