Abstract
A data communication system installed in an electric machine includes a transmission terminal and a reception terminal both mounted on the electric machine, a transmission-side opposed conductive member disposed on the transmission terminal, a transmission circuit for applying voltage between the transmission-side conductive member and the conductive body, thereby changing electric field generated on the entire surface of the conductive body, the voltage being changed according to information to be transmitted, a reception-side opposed conductive member provided on the reception terminal, thereby being capable of generating potential difference according to the electric field between the conductive body and the reception-side opposed conductive member, and a reception circuit for receiving the information based on a change in the potential difference between the conductive body and the reception-side opposed conductive member.
