している。With the recent miniaturization of equipment, there is a strong demand for small motors. In designing a motor with a smaller size and comparable characteristics, there is an approach to improving the magnetic circuit. Specifically, the magnetic circuit J-9 has all magnets placed on one side of the rotor coil, and the magnetic circuit has magnets placed on both sides of the rotor coil so as to sandwich the rotor coil. It is well known that he is excellent at this.

では、磁石の内径と磁石の厚み分の体積が無駄な空間と
なってし１い、小型化には適さない。However, when a motor employing the above-mentioned magnet-opposed magnetic circuit is configured with a conventional rotor, the thickness of the rotor coil where the commutator is located on the surface W, and the thickness of the wiring connected to C is the total thickness limit for the motor. On the other hand, on the opposite side without a commutator, the volume corresponding to the inner diameter of the magnet and the thickness of the magnet becomes wasted space, which is not suitable for miniaturization.
