摘要:
A rotor 10 is constructed of a rotating shaft 7 and a semicylindrical rotating core 9 mounted on the shaft 7. A stator is coaxially arranged, with the rotor 10 being surrounded by a pair of annular stator coils 11 and 13 arranged one above the other in an axial direction of the rotor 10. A yoke member of the coils 11 and 13 is provided with magnetic material plates 19, 21, 23 and 25. The plates 19 and 21 for the coil 11 have halves 19A and 21A with inner peripheral portions protruding radially inwardly to approach the rotor 10, while the remaining plates 23 and 25 for the coil 13 have halves 23A and 25A with their inner peripheral portions protruding radially inwardly to approach the rotor 10. The halves 23A and 25A are oppositely disposed from the halves 19A and 21 A so as to have the coils 11 and 13 be opposite to each other in phase of the inductance as the rotor 10 rotates.
