A motor has windings and a control device, which applies appropriately one-way current to each of the windings. Two full-pitch windings, which are located adjacently to both ends of an A-phase stator magnetic pole, and driving transistors are connected in series to each other to supply an A-phase current component, thereby exciting an A-phase magnetic flux component passing through the A-phase stator magnetic pole, resulting in generation of torque. This excitation is also applied to other phases. The respective stator magnetic poles can be excited selectively, and voltages across both ends of the serially connected windings become a voltage for corresponding magnetic flux components which should be provided by the windings, thus providing a more simplified motor structure and higher motor performance. The windings and transistors can be used commonly in two phases, providing an improved usage rate, thus making the motor more compact in size and reducing manufacturing cost.

A reluctance motor with a rotor which rotates about a longitudinal axis and an individual stator. The rotor has on a surface close to the stator a toothing, and the stator has on the surface close to the rotor a corresponding toothing, the teeth of which extend longitudinally. The stator has at least two cavities arranged successively in the longitudinal direction each configured to receive a toroidal coil which can be energized. The windings of the toroidal coils are wound concentrically around the longitudinal axis. The stator is penetrated on the side close to the rotor to form a respective air gap toward the cavities. The air gap is aligned in a circular-cylindrical manner and concentrically to the longitudinal axis and has a constant height longitudinally which is smaller than the extent of the toroidal coil in the direction of the longitudinal axis.

A switched reluctance motor, of an outer rotor type, includes an inner stator having a plurality of salient poles, around which coils of five phases are wound in concentrated winding, and an outer rotor having a plurality of rotor yokes that are formed separately, each being magnetized to have two magnetic poles generated in the rotor yoke, and having a rotor body that is constructed of a non-magnetic conductive material for retaining the plurality of rotor yokes. The switched reluctance motor is configured to excite corresponding salient poles, by simultaneous use of coils of two phases among the coils of five phases.

An armature portion includes a first and second armature core, and a core coupling portion that magnetically couples the first armature core to the second armature core. The first and second armature core includes magnetic pole groups that are magnetically coupled, respectively. A first and second magnetic flux are formed in the armature portion by magnets. A first magnetic circuit in which the first magnetic flux flows includes three magnetic pole groups, magnetic field cores, and the magnets. A second magnetic circuit in which the second magnetic flux flows includes two magnetic pole groups, a core coupling structure, the magnetic field cores, and the magnets. This structure reduces magnetic saturation of the magnetic circuit formed on the armature portion and eliminate the need to magnetically divide the armature cores in the machine moving direction, thereby increasing the intensity of the armature.
