A data communication system installed in an electric machine (10) includes a transmission terminal (51A, 51C) and a reception terminal (51B, 51C) both mounted on the electric machine (10), a transmission-side opposed conductive member (52S) disposed on the transmission terminal (51A, 51C), a transmission circuit (53) for applying voltage between the transmission-side conductive member (52S) and the conductive body (20), thereby changing electric field generated on the entire surface of the conductive body (20), the voltage being changed according to information to be transmitted, a reception-side opposed conductive member (52J) provided on the reception terminal (51B, 51C), thereby being capable of generating potential difference according to the electric field between the conductive body (20) and the reception-side opposed conductive member (52J), and a reception circuit (54) for receiving the information based on a change in the potential difference between the conductive body (20) and the reception-side opposed conductive member (52J). |
