摘要： A linear motor is capable of miniaturization of a device, sharing of effective magnetic fluxes between the magnetic poles adjacent to each other, and decreasing a magnetic attractive force acting between a mover and an armature, and a linear motor drive system. The linear motor includes a mover, formed by lining up a plurality of pieces of permanent magnets or magnetic materials while inversing a magnetization direction thereof, and an armature. First and second magnetic pole teeth are disposed in such a way as to vertically tuck the permanent magnet or the magnetic material. A magnetic material links the first magnetic pole tooth to the second magnetic pole tooth, thereby forming a path for a magnetic flux, and windings are disposed on the first magnetic pole tooth and the second magnetic pole tooth, respectively. At least two units of the armatures are lined to be linked to each other.

摘要： An electrical rotating machine includes: a rotating shaft; a rotor, equipped with permanent magnets, and formed to rotate with the rotating shaft, a stator disposed in opposition on an outside-diametral side and via a clearance with respect to the rotor; and anti-demagnetization conductors extending in the axial direction of the shaft, the conductors each being disposed inside the rotor, wherein: the anti-demagnetization conductors are provided in pairs of two for each of magnetic poles of the rotor; the two anti-demagnetization conductors forming a pair are electrically interconnected; and, inside the rotor, the two paired anti-demagnetization conductors are disposed at different-polarity sides of two corresponding permanent magnets in a circumferential direction of the rotor, the different-polarity sides each being more adjacent to the circumferential direction of the rotor than to an end portion of one of the two corresponding permanent magnets existing close to each other in one magnetic pole.
