    Abstract: A permanent magnet rotating machine includes a rotor with a permanent magnet having circumferential magnetic poles with a skew at boundaries between magnetic poles of the permanent magnet, and a stator having a stator iron core in an almost cylindrical shape and convex poles protruding inwardly, the rotor being disposed within the stator. A skew angle of the skew is smaller than a theoretical angle θs (electrical angle) and larger than one-half the theoretical angle θs, wherein the theoretical angle θs is defined as, θs=180×(number of magnetic poles in the rotor)/smallest integer of which both the number of magnetic poles in the rotor and the number of magnetic poles in the stator are factors) [deg.].

    Abstract: A brushless motor A includes a permanent magnet used as a rotor 1 that is driven by three-phase power supply, wherein the permanent magnet is magnetized by a trapezoidal magnetization, and the trapezoidal magnetization is applied such that a generation period of a cogging torque is set to almost half of the generation period of the cogging torque generated when the permanent magnet to which a square magnetization is applied is used. In this brushless motor A, preferably a skew magnetization is also applied to the rotor 1. Further, in case of driven by a sinusoidal-wave current, the skew angle is set to the angle in the range that has ±15% of the reference angle as an upper limit and a lower limit by a combination of a trapezoidal magnetization and a skew magnetization.

    Abstract: A stator 10 has a pair of pole parts 11 extending inwardly in opposite directions. The pole parts 11 are wrapped with inductance coils 12. A rotor 14 is equipped with a pair of permanent magnets 13 that essentially face toward the pole parts 11. The permanent magnets 13 are magnetized radially, and are shifted angularly from positions in direct radial alignment with the pole parts 11. An excitation current is applied to the coils 12 to cause the rotor 14 to move through a specific angular range by a magnetic field induced in the pole parts 11 and magnetic fields of the permanent magnets 13. The radial misalignment between the pole parts 11 and the permanent magnets 13 improves the performance characteristics of the rotary solenoid.
