Abstract: A brushless core motor featuring improved positional relationship between magneto-sensitive elements and core windings to prevent distortion of the output from the elements, enable a reduction in the thickness of the motor, and assure reduced and uniformly distributed leakage of magnetic flux. The motor includes an armature core having a plurality of salient poles, a plurality of windings in "m" phases (the term "m" expresses an integer.gtoreq.two) which are wound on the salient poles, a rotor magnet rotatable in an opposed relation with the salient poles, and "n" magneto-sensitive elements (the term "n"=an integer satisfying the relation of m.gtoreq.n) for detecting the magnetic poles of the rotor magnet in order to effect electric conduction control of the windings in the m phases. The magneto-sensitive elements are disposed in the vicinity of the rotor magnet, and, of the salient poles, having no windings are disposed adjacent the magneto-sensitive elements.
