Abstract
The invention concerns a compass having an electro magnetic half-shell transformer energy transmission and opto electronic data transmission. To avoid a slipring connection during the transfer of supply voltage at least one winding on the primary half-shell is connected to a controllable input voltage source via a H-bridge circuit, and at least one secondary winding having taps is provided at the other half-shell coil.

A compass with electromagnetic half-shell energy transmission and optoelectronic data transmission,
- characterized in that
- in the half-shell transformer (14,16) the at least one winding on the primary half-shell is connected via an H-bridge circuit (12) to controllable input voltage source (10), and at least one secondary winding is provided on the other half-shell coil, which secondary winding is provided with a plurality of taps for the voltage supply of, among other things, the heating, the internal electronics controlling the voltage supply, and the gyrosphere motor supply.
