Title: Variable-gap gyro motor
Inventor: TAKAKURA MASAMI
IPC: H02K41/06
Filed: 1998-12-16
Abstract: PROBLEM TO BE SOLVED: To reduce the weight of a motor, and to improve response speed or the like by arranging a magnetic body being annually formed so that the magnetic body becomes a magnetic path being used as the passage of flux for interlinking with a rotor at a rotation center side as compared with an electromagnet along with the magnetic pole of the electromagnet. SOLUTION: A magnetic body 10 is sealed to a frame 2 at the rotation center side as compared with an electromagnet 3 so that a ring concentric with a ring being formed by the aggregate of the electromagnet 3 is formed. Along with a magnetic pole 4 of the electromagnet 3, a magnetic path being used as the passage of flux ϕ for interlinking with a rotor 6 is formed.  At this time, a surface opposite to the rotor 6 of the magnetic body 10, namely, a surface is inclined so that the surface becomes a conic shape with a center angle θ1 as a whole along with the magnet pole 4 of the electromagnet 3, and at the same time lining 11 is applied to improve the overall friction force and wear resistance when the surface is brought into contact with the rotor 6, thus dividing the interlinking flux with the rotor 6 into two portions, and hence dividing the thickness t2 of the rotor 6 into half as compared with a case without the magnetic body 10.
