Title:
TORQUE MOTOR
Document Type and Number:
Japanese Patent JPS6139839
Kind Code:
A
Abstract:
PURPOSE:To reduce the size of a torque motor by providing a magnet in a housing to construct a core with a portion for directing to a magnetic flux and a portion for directing a magnetic flux externally from the core. CONSTITUTION:When coils 4a, 4b are energized externally, a magnetic flux is generated to a stationary core 1 from a magnet 7. Since the coils 4a, 4b side of a magnet 8 is N-pole between the magnet 8 and the core 1, a magnetic flux directed from the magnet 8 to the core 1 is generated. Since the coils 4a, 4b side of a magnet 9 is S-pole between the magnet 9 and the core 1, a magnetic flux is generated from the core 1 to the magnet 9. Further, since the coils 4a, 4b side of a magnet 10 between the magnet 10 and the core 1 is S-pole, a magnetic flux is generated from the core 1 to the magnet 10. A torque is generated by the magnetic fluxes, and the coils 4a, 4b are rotated.
