Abstract

Example implementations may relate to a rotary transformer configured to transmit data. In some implementations, the rotary transformer may include a primary transformer component with a primary winding magnetically coupled to a secondary transformer component with a secondary winding. The rotary transformer may also include a resonant circuit including a frequency determining element and an amplifier. The frequency determining element may consist of the primary and secondary windings connected in parallel to respective capacitors. The primary transformer component may be coupled to a fixed-frequency signal generator. The rotary transformer may include a modulator coupled to the secondary transformer component and configured to vary the phase of the resonant circuit to generate an output signal and a demodulator coupled to the primary transformer component and configured to demodulate the output signal.
