Abstract
1,232,692. A.C. generators, E. HAYASAKA. 27 May, 1968 [29 May, 1967], No. 25197/68. Heading H2A. A homopolar A.C. generator applicable to tachometers comprises a rotary driven shaft 10 upon which is mounted with its magnetic axis coincident with the axis of the shaft a rotary magnetic pole body 11 having N and S poles adjacent one of which is mounted a partially cylindrical polepiece 12, and a stator having in a yoke 14 cores 15a, 15b wound with armature coils 17a, 17b and provided with partially cylindrical core pieces 16a, 16b of substantially the same axial length as the polepiece 12 from which they are spaced by air gaps c, the structure providing a magnetic flux path from one body pole N, through the polepiece 12, the air gaps c, the core pieces and cores 16a, 16b, 15a, 15b, and the yoke 14, to the other body pole S. The body 11 is either an electromagnet or a permanent magnet, e.g. of barium-ferrite or manganese-ferrite, and the polepiece 12 has a square, triangular or sinusoidal developed shape to produce a corresponding output waveform. In addition to the 1-ph. single pole, single element generator shown, the Specification discloses 3-ph., two pole, two element generators.
