<p>PURPOSE:To constitute the rotary transformer of multiple channels in a limited dimensional limitation by dividing a rotor into plural ones, disposing primary winding wires to the respective ones, allowing them to be opposed to a stator and magnetically combining the rotors and the stator. CONSTITUTION:A groove 3 is provided in the stator 1 consisting of a magnetic substance and a secondary winding wire 4 is disposed in the groove 3. On the other hand, the rotors 2-1 and 2-2 form an annulus ring as a structural body and they are magnetically independent rotors. Then, the primary winding wire 5 is disposed in the groove 3 of the rotor and the end of the winding wire is taken out to the outside. The stator 1 and the rotors 2 are magnetically combined so that the surfaces thereof where the grooves 3 are formed may be opposed to each other with a narrow gap. With such constitution, a magnetic circuit formed of the rotor 2-1 and a part of the stator 1 constitute one transformer and the rotor 2-2 and a part of the stator 1 constitute another transformer so as to be multiple channel, thereby miniaturizing the transformer.</p> |
