Abstract
An electrical rotary transformer for inductive energy transmission may include a rotary transformer stator, a rotary transformer rotor rotatable relative to the rotary transformer stator, and a capacitive coupler for capacitive electrical signal transmission between the rotary transformer stator and the rotary transformer rotor. The rotary transformer stator may include a primary coil. The rotary transformer rotor may include a secondary coil inductively couplable to the primary coil. The capacitive coupler may be partly formed on the rotary transformer stator and the rotary transformer rotor. The capacitive coupler may include two plate capacitors that may each include a first and a second plate element. The two first plate elements may be arranged on the stator. The two second plate elements may be arranged on the rotary transformer rotor. The first plate element and the second plate element of each plate capacitor may be disposed opposite one another for capacitive coupling.
