Title:
TWO-PHASE FREQUENCY GENERATOR
Document Type and Number:
Japanese Patent JP3172104
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To minimize an error between the output voltage and phase of a two-phase frequency generator by disposing an A-phase generating coil and a B-phase generating coil with their power generating conductor adjacent to them at a particular pitch mutually for a stator of two-phase frequency generator.
SOLUTION: In a stator for two-phase frequency generator, a U-shaped power generating conductor where the outer ends of A-phase power generating conductors, for example, a-1, a-2 are formed integrally by a connection conductor o-1, and a U-shaped power generating conductor where the inner ends of B-phase power generating conducting conductors, for example, b-3, b-4 are formed integrally by a connection conductor p-2 are disposed alternately. Such an arrangement is made so that an A-phase magneto coil and B-phase magneto coil may be disposed by 1/2 pitch mutually with the U-shaped power generating conductors adjacent to them. It is thus possible to minimize an error between two-phase output voltage and a phase angle even if a little deviation is present between the center of permanent magnet of the rotor and the center of the generating coil.
