Abstract

PURPOSE:To improve the S/N ratio, by eliminating the influence of induction flux from an armature winding and external induction field from a transformer or the like. CONSTITUTION:A motor comprises a frequency generating rotor 8 which rotates concentrically and integrally with field magnets 5 having P pairs of poles, and a frequency generating stator 9 having a generation coil 10 for producing an electric signal of frequency corresponding to the revolution speed of the rotor. The generation coil is placed at a prescribed pitch in the form of a notched ring centering the axis of the rotation. The angle between both the ends of the coil is set at nX360 deg./P. Induction noises due to leakage flux are thus cancelled by each other. The motor is useful to drive an audio set or the like.
