Title:
MOTOR WITH DISCOID ROTOR SECTION
Document Type and Number:
Japanese Patent JPH07107720
Kind Code:
A
Abstract:

PURPOSE: To decrease the number of the components of a rotor section, to reduce rotary load, to prevent the limitation of the positional relationship of the rotor section and a stator section, to obviate wasteful energy consumption during revolution by using a doughnut-shaped superconductor or ferromagnetic substance and to restrain the extent of magnetic flux.

CONSTITUTION: A rotating shaft 13 is fixed at the center of a discoid rotor section 11 having specified thickness, the rotor section 11 has a superconductor 16, in which a strong magnetic field can be magnetized and which has specified thickness, and the surface of the superconductor 16 is magnetized in an N pole or an S pole and a rear thereof is magnetized in the S pole or the N pole regarding a motor 10 with the rotor section 11 and a stator section 12. The stator section 12 has a plurality of magnetic cores annularly disposed while being oppositely faced to the rotary locus of the rotor section 11 and an exciting coil 19 wound on these magnetic cores 18.
