Title: Magnetic bearing spindle
Inventor: NAKASEKI TSUGUTO
IPC: H02K5/04
Filed: 1986-02-18
Abstract: PURPOSE:To strengthen the axial rigidity and improve centrifugal strength and to obtain superhigh speed rotation by composing a motor rotor with hollow cylindrical magnet materials of Fe Cr Co line. CONSTITUTION:A hollow cylindrical motor rotor 1 is formed by hard magnetic steel materials of Fe Cr Co line. It is fitted into the outside circumference of a shaft 2 for fixing, which is made of non-magnetic steel, and is covered with a motor stator 3. The shaft 2 is horizontally and rotatably supported by radial magnetic bearings 4 and positioned in the axial direction of a thrust magnetic bearings 5. The motor stator 3 produces rotating magnetic field and rotates a motor rotor 1. As the motor rotor 1 is made of semihard magnetic materials of Fe Cr Co line, the wall thickness can be thinned as compared with that of laminated silicon steel plate. The outside diameter of the shaft 2 can therefore be larger, which is favourable to the axial rigidity, natural frequency and centrifugal strength.

Abstract: PURPOSE:To make it possible to detect filament breakage of a dc lamp with a high sensitivity by connecting terminals of one side of a 1st, 3rd, and 2nd, 4th switch elements respectively to 1st and 2nd terminals, and connecting the other ends of the 1st, 4th and the 2nd, 3rd switch elements respectively to one end and the other end of a wire. CONSTITUTION:When a 1st control signal A is inputted, a 1st and a 2nd switch elements 1, 2 are turned on. When a 2nd control signal B is inputted, 3rd and a 4th switch elements 3, 4 are turned on. When the 1st control signal A is inputted, a current flows from one end of a wire 9 to its other end. When the 2nd control signal B is inputted, a reverse current flows in the wire 9. As a result, an alternate current flows through the wire 9 and a pickup coil 20 detects the current with a high sensitivity without its core being magnetized with a direct current. This arrangement makes it possible to detect a filament breakage by means of the pickup coil with a high sensitivity.
