摘要： PURPOSE:To enable to eliminate a brush and to reduce the inertia of a brushless motor by forming a revolving magnetic field only by a magnetic flux of the same direction in a field space, and acting a rotor formed to circumferentially alternately vary the magnetic resistance to the field. CONSTITUTION:A circular permanent magnet 3 is contained between inner and outer cylinders 1a and 1b of a yoke 1. The magnet 3 is magnetized, for example, to be the same pole such as N-pole on the outer periphery, and S-pole on the inner periphery, and the magnetic flux of a field space 4 becomes in the same direction. Four field control windings 5a, 6a and 5b, 6b are secured in the prescribed sequence and interval on the outer periphery of the magnet 3. A rotor 7 encloses the windings 5a, 6a, 5b, 6b, and is disposed in the space 4. The windings 5a, 5b, 6a, 6b are sequentially switched in the energization, thereby rotating the rotor 7.
