Abstract
PURPOSE:To perform adjustment quickly and easily by making it possible to adjust the relative positions of a rotor and a stator, wherein a pair of cut-out portions are symmetrically provided on the end surface of the magnetic pole formed concentrically with the rotor, only in the specified direction. CONSTITUTION:A motor is constituted by a stator 10, a coil core 20, a driving coil 40 which is wound around a bobbin 30, and a rotor 50. An end surface 14 of a stator pole 12 is concentrically formed with the rotor 50, so that said end surface 14 opposes the rotor 50 with a specified gap being provided. At approximately symmetrical positions of individual end surfaces 14, are provided a pair of cut-out portions 15 for determining the stationary position of the rotor 50 when a current is not conducted. In this constitution of the motor, the starting voltage varies greatly when the relative position of the rotor 50 and the stator 10 is shifted in the direction perpendicular to the line L connecting a pair of cut-out portions 15. In this case, for example, mounting holes 16 and 22 provided in the stator 10 and the coil core 20 are formed in a long shape, and the relative position of the stator 10 with respect to the rotor 50 can be adjusted in the direction perpendicular to the line L.
