PURPOSE:To miniaturize the whole motor-particularly, shorten axial length-by mounting a magnetic induction element to a side surface within the axial length of a stator and displacing a pole center in a section oppositely faced to the magnetic induction element of a permanent magnet in the circumferential direction by a fixed quantity. CONSTITUTION:A magnetic induction element 10 is positioned within the axial length of a stator 5, and mounted on a side surface in the vicinity of the end section of a first magnetic pole 6a within a diameter formed, extending pole faces 6c, 6d. The pole center of a section 2a oppositely faced to the magnetic induction element 10 of a permanent magnet 2 is displaced in the circumferential direction on the revolution side by a fixed quantity. Accordingly, the mounting space of the magnetic induction element 10 is shaped within the axial length of the stator 5, thus miniaturizing the whole motor-particularly, shortening axial length.
