Patent ID: 8126298

Claim:
A transmission device for transmission of data between a rotor and a stator, the transmission device comprising: a first pair of transmission units and a second pair of transmission units, one of the first pair of transmission units and the second pair of transmission units being a transmitter and the other of the first pair of transmission units and the second pair of transmission units being a receiver, one of the transmitter and the receiver being arranged on the rotor and the other of the transmitter and the receiver being arranged on the stator; and a control unit configured to control a handover time as a function of a relative phase angle between the first pair of transmission units and the second pair of transmission units, wherein the first pair of transmission units and the second pair of transmission units are arranged in relation to each other so that, when the rotor is rotating, at the handover time, transmission units of a pair of transmission units moving towards each other and transmission units of the other pair of transmission units moving away from each other are in a transmission position in relation to one another.
