  • Rotary transformer
    Patent number: 5347256
    Abstract: Disclosed is a rotary transformer transmitting signals without any physical contact between its rotary part and its stationary part. In the rotary transformer, cores having different frequency characteristics are integrally combined so that signals having a plurality of different frequency ranges can be selectively transmitted by cores having frequency characteristics optimum for such frequency ranges, thereby improving the signal transmission efficiency and reducing the size of the rotary transformer system.
