<p>PURPOSE:To eliminate cross-talk by making the opposing faces of rotor and stator convex and concave faces to engage each other with a specified distance and dividing those faces and providing non-magnetic bodies between those faces in rotor and stator that rotate relatively to each other and are provided with a plurality of coils on their opposing faces in order to give electromagnetic coupling between them. CONSTITUTION:When a stator 5 and rotor 6 that are opposite to each other form a rotary transformer, a plurality of annular magnetic bodies 81 and 82 are fit on the outer circumferential face of the stator 5 with a distance between them, and coils 111 and 112 are provided on the tip ends of those magnetic bodies. Further, annular magnetic bodies 91 and 92 that enclose the annular magnetic bodies 81 and 82 are provided on the rotor 6 in such a fashion that the magnetic bodies are positioned opposite to the stator 5, and on the inside of the magnetic bodies 91 and 92 coils 121 and 122 are formed that are opposite to the coils 111 and 112 respectively. In the gap between the separated magnetic bodies 91 and 92 a non-magnetic material layer 10 is inserted. With this construction magnetic coupling becomes large and cross-talk is eliminated.</p> |
