Abstract

PURPOSE: To permit the higher efficiency of electrode transducer by providing a magnetic coupler for rotor and stator at more than two places.
CONSTITUTION: The rotor consisting of the coil 1, the magnetic core 2, the stator to lead the magnetic energy generated in the magnetic core, and a permanent magnetic rotating according to the magnetic pole of the stator 3 is provided, and a magnetic coupler for the rotors 4 and 14 and the stator 3 is provided at more than two places 3a and 3b. Thus, static torque is shared with both the rotors 4 and 14, so that the static torque for each rotor becomes 1/2 of the conventional one. For this reason, as for the input energy, half of the conventional requisite energy is sufficient for the rotor of stator, or the current 16 as shown in the Fig. And, since the stator 3 is separated into the 3a and 3b, the starting of the rotors 4 and 14 can be performed sufficiently by applying a current two times as much as the current 16, or the same current 6 as the conventional one.
