Motor capable of generating an electric signal having a particular and precise frequency and a rotary magnetic head apparatus using the same

摘要

A motor capable of generating an electric signal having a particular and precise frequency may be used in a rotary magnetic head apparatus for a video tape recorder. A wiring pattern for generating the signal is disposed on a stator opposite a rotor. Alternating magnetic flux provided by movement of the rotor produces the signal. Gaps in the wiring pattern allow the wiring pattern and wiring for iron core assemblies also disposed on the stator to be disposed on a single circuit board. A toroidal coupling line and a loop coupling line close the loop without crossing the gaps.
