摘要： A brushless direct current (BLDC) motor of axial gap type includes a rotational axis, a stator rotatably connected to the rotational axis, a rotor disposed apart from the stator in an axial direction of the rotational axis, fixedly connected to the rotational axis, and including a permanent magnet formed on an inner surface thereof to face the stator. Further, the stator is formed as wiring board and includes a plate-like board body and a coil pattern. The board body is disposed in a horizontal position with regard to the rotor and has a central hole into which the rotational axis is inserted. The coil pattern is formed in the board body and arranged in a radial form around the central hole.

摘要： A stator of a switched reluctance motor includes a stator core part, stator coiling parts, stator salient parts, and pairs of permanent magnets. The stator coiling parts protrude inwardly from the stator core part and have coils wound on an external side thereof. The stator salient parts protrude inwardly from the stator core part and are disposed between the stator coiling parts. Each pair of the permanent magnets is inserted into each of the stator coiling parts and magnetized in the same direction as a direction of a magnetic field generated by the excitation of the coils. This stator has an electromagnetic structure designed to prevent the reversal of a magnetic field generated by the excited coils. The output of the motor is enhanced by inserting the permanent magnets so as to be magnetized in the same direction as a direction of a magnetic field generated by the excited coils.
