Abstract

PURPOSE: To reduce noises due to the alternating magnetic field of a motor by making the outside core of a rotary transformer much longer than the coil grooves of the uppermost and lowermost parts and obtaining a shield material function by surrounding the rotary transformer with the motor rotor and a motor stator positioned below it.
CONSTITUTION: An upper cylinder 8 provided with a magnetic head 9 on its peripheral reverse surface and a lower cylinder 4 are arranged opposite each other at an interval and coupled with each other by a shaft 6 supported by a bearing 5, and a disk 7 whose peripheral drops is fitted onto the other periphery of the shaft 6. Then the shaft 6 is surrounded with a rotary transformer pair 3 of an outside core 3a and an inside core 3b, but a core 3a is set sufficiently long on the uppermost and lowermost coil grooves 3c and 3d among coil grooves provided opposite the cores 3a and 3b. Then, the outer periphery is surrounded with the motor rotor 1 and stator 2 and the core 3a stops magnetic flux 10 leaking there from entering the transformer pair 3.
