Abstract: A synchronous rotating electric machine includes an armature and a rotor. The armature has an armature coil wound on an armature core. The rotor has permanent magnets embedded in a rotor core so as to be spaced from one another in a circumferential direction of the rotor core. The rotor has a structure such that: the rotor core has yoke portions each of which is formed between one circumferentially-adjacent pair of the permanent magnets; and all of the permanent magnets are magnetized in the same magnetization direction along the circumferential direction of the rotor core so that for each circumferentially-facing pair of circumferential side surfaces of the permanent magnets, the polarities of the circumferential side surfaces of the circumferentially-facing pair are opposite to each other. With the above structure, flow of magnetic flux generated by the permanent magnets changes depending on whether electric current is flowing in the armature coil.

Abstract: A rotor includes a rotor core and permanent magnets. The rotor core includes annular bodies that are stacked in a stacking direction and each formed of core segments arranged along a circumferential direction. The number of the core segments in each of the annular bodies is set based on k, where k is the number of magnetic poles formed by the permanent magnets. The rotor core has n through-holes, where n≧k. The rotor further includes n fixing members each of which extends in the stacking direction through one corresponding through-hole of the rotor core. Between each circumferentially adjacent pair of the core segments, there is formed a gap that is greater than a clearance provided between the through-holes of the rotor core and the fixing members. At least one of the annular bodies is circumferentially offset from another annular body by an integer multiple of one magnetic pole.

Abstract: A double-stator motor of an example embodiment includes: an annular rotor connected to a rotary shaft and integrally rotates with the rotary shaft, an inner stator arranged radially inward of the rotor, and an outer stator arranged radially outward of the rotor. The rotor includes a plurality of segments annularly arranged in the circumferential direction, spaced apart from each other by a predetermined distance, and a plurality of permanent magnets each interposed between circumferentially adjacent segments, the permanent magnets being alternately magnetized in the circumferentially opposite direction. The rotor, the inner stator and the outer stator have the same number of poles. The inner and outer stator windings of the inner and outer stators, respectively, are connected so that their phases are reversed to each other. Thus, the magnetic fields generated by the magnetomotive forces of the inner and outer stators are applied to specific segments in parallel.
