Abstract

PURPOSE: To increase the magnetic flux variations to enhance the output voltage of a tachometer generator by forming 360° of an electric angle at the interval of magnetic members entering into the magnetic poles of a pair and odd times of 180° of an electric angle between the respective magnetic poles of the same polarity.
CONSTITUTION: Two magnetic poles 4a, 4b and 5a, 5b are so arranged at both ends of permanent magnet 3 that different polarities of the magnetic poles 4a, 5a and 4b, 5b form a pair. A gear 1 having magnetic members 1a, 1b,... enters between the magnetic poles of a pair to thereby form a magnetic path to induce voltage at the respective coils 5a, 5b, 6a, 6b. The electric angle between the members 1a and 1b is formed at 360°, and so formed that, assuming that n represents positive integer, the electric angle between the respective magnetic poles of the same polarity, i.e., the poles 4a, 4b and 5a, 5b becomes 360(2n-1)°. Thus, it can concentrate the magnetomotive force of the magnet 3 between a pair of the magnetic poles to increase the magnetic flux variations to thereby enhance the output voltage of this tachometer generator.
