摘要： PROBLEM TO BE SOLVED: To reduce a torque ripple, an oscillation and a noise by effectively obtaining an effect similar to a skew effect.
SOLUTION: The rotor of a reluctance type rotating electric machine includes a rotor core obtained by laminating many annular silicon steel sheets and divided into four blocks 3, 4, 4 and 3. The block 3 is formed by displacing a magnetic uneven part by a predetermined angle in an opposite direction to a rotating direction X with a centerline passing a key engaged with the keyway of a rotary shaft as a reference, and the block 4 is formed by displacing a magnetic uneven part by a predetermined angle in the rotating direction X with the centerline as a reference. Thus, for example, the locus of the centerline Lc passing a center of the magnetic recesses of the blocks 4, 4, and the locus of the centerline Lb passing a center of magnetic recesses of the blocks 3, 3, are not disposed on one straight line to become a zigzag state, and the effect similar to the skew effect can be obtained.

SOLUTION: The rotor of a reluctance type rotating electric machine includes a rotor core obtained by laminating many annular silicon steel sheets and divided into a plurality of blocks. One block 3 is formed by displacing a magnetic recess 8 and a magnetic protrusion 9 in an opposite direction (clockwise direction) to a rotating direction X by an angle Δθ with a centerline Lo passing keys 10, 11 as a reference, and forming the magnetic recess 8 and the magnetic protrusion 9. Other blocks 4 are formed by displacing a magnetic recess 15 and a magnetic protrusion 16 by an angle Δθ with the centerline Lo as a reference in the rotating direction X (counterclockwise direction), and forming the magnetic recess part 15 and the magnetic protrusion 16. Thus, for example, the locus of the centerline Lb passing a center of the magnetic recess 8, and the locus of the centerline Lc passing a center of the magnetic recess 15, are not disposed on one straight line to become a zigzag state, and the effect similar to the skew effect can be obtained.

摘要： PROBLEM TO BE SOLVED: To provide a running guide device for an elevator whereby a car of an elevator can be smoothly and stably guide supported. SOLUTION: In a controller 8, normally based on either one detection signal of two gap detectors 6a, 6b, so as to fix a gap, magnetic force of an electromagnet 51 is controlled. In the case of one detection signal rapidly changing, it is switched to a detection signal from the other gap detector, so as to fix the gap, magnetic force of the electromagnet 51 is controlled. In this way, even in the vicinity of a step difference in a joint or the like of a guide rail 4, the magnetic force can be smoothly controlled.

摘要： PROBLEM TO BE SOLVED: To load damping force against the vibration of a rotating shaft at the critical speed of the rotating shaft, and operate a motor beyond the critical speed stably by controlling the current which flows through a damping control winding, so that the relation between a rotating field which the damping control winding generates and the direction of imbalance forms a specific expression. SOLUTION: A current flowing through a damping control winding 13 is controlled so that the expression of (p+1).β=pa0 +±/2+(ω+ωm)t is satisfied through a controller 16, where the imbalance directional angle of a rotor 2 is α, the pole position (angle) of a rotating field is β, the damping control winding 13 is 2(p+1) poles, and the frequency of the current to be supplied to the damping control winding 13 is (ω+ωm), and the phase difference from the pole position of the rotor 2 is set to pα+π/2. The magnetic attraction force acting on the rotor 2 acts as a damping force with respect to the centrifugal whirling of a shaft, and suppress its runout. As a result, it is thus possible to operate a motor beyond a critical speed.
