Abstract

PURPOSE:To obtain a large frequency generated with a limited number of salient poles by differentiating the number of salient poles provided on a rotary section and a fixed section of a frequency generator from each other. CONSTITUTION:A frequency generator is provided with a fixed section 22 fastened on a motor body and a rotary section 20 fastened on an output shaft 12 of a motor. Several salient poles 34 formed on the outer periphery of the fixed section 22 face as many salient poles formed on the inner periphery so as to vary the level of magnetic flux from a permanent magnet 26 whereby a coil 28 obtains an electromotive force of a frequency to match the revolutions of the rotary section 20. The salient poles 34 of the fixed section 22 and the salient poles 36 of the rotary section 20 are so differentiated from each other that one is 1.4-1.6 fold as large as the other, for example. Thus, the rotation of the rotary section 20 increases the frequency of facing between the salient poles 34 and 36 to obtain a high frequency.
