    Abstract: Salient poles made from soft magnetic steel plates have tip sections of approximately the same length as a rotor magnet. The salient poles are constructed with laminations in the circumferential direction, with axial dimensions adjusted with respect to the circumferential dimensions determined by the constraints of the winding to allow winding sections with a minimum required cross-sectional area so that magnetic saturation does not occur. These winding sections are inserted into coils wound with magnet wire, and press fitted into the stator which makes the magnetic circuit with the salient poles and forms the armature.

    Abstract: A motor having an external rotor, or "inside out motor" has a split C arrangement of ferromagnetic members which function as the poles of the electromagnet in the motor. The ferromagnetic members are generally C-shaped and mounted on opposite end caps of the motor. The ferromagnetic members on the opposing end caps are angularly offset from each other. The ferromagnetic members on each end cap are also spaced apart from each other, and receive a portion of the motor windings within them. The motor is constructed for assembly using few or no separate fastening devices to secure the components together. In one embodiment, a bearing core serves as the base on which all parts are assembled.

    Abstract: To reduce as much as possible the motor vibration due to the effect of harmonic components contained in the induced electromotive force waveform induced in the armature coil. In a motor structure, the pole tooth shapes of one pole tooth and the corresponding pole tooth thereto constituting one phase are made different from each other by changing their areas or amounts of skew, whereby the third harmonics caused by variations in the magnetic fluxes interlinking with these pole teeth are caused to cancel each other. Thus, the rotational vibration which has hitherto been a problem can be reduced and, further, the accuracy of the rotor movement can be improved without lowering the dynamic torque characteristic of the motor.

    Abstract: A low armature reacting magnetic circuit includes of an integral combination of magnetic circuit structures, one for each magnetic pole including at least the two main magnetic field poles of the machine, to achieve magnetic flux circuits of two or more poles within an interference-free magnetic flux circuit structure. Such a circuit provides a high magnetic resistance to inhibit the cross magnetic flux associated with the armature, and improves commutation effectiveness. Further efficiencies are achieved through the addition of interpose auxiliary distributed magnetic circuits and commutating poles. Indentations providing through-holes for ventilation and heat dissipation can be made in one or both main magnetic field conducting end structures.

    Abstract: A rotor for a two-pole synchronous reluctance or a switched reluctance motor can be constructed from a stack of flat, planar laminations of grain-oriented materials. To enhance the necessary anisotropy of reluctance, slots are provided in the lamination along the magnetic flux lines in the preferred grain direction. The laminations may be provided with an essentially circular outer perimeter, and slots for a squirrel cage winding provided. A complete, efficient squirrel cage winding can thus be provided for a two-pole synchronous reluctance motor for starting purposes.

A plurality of poles extend between and are secured to the supports. The stator has either distributed winding or salient phase pole windings associated with at least some of the poles with an opening between adjacent poles in the regions of the slots in the supports.

Each disc is made of a magnetically permeable material and has either an inner face of electrically conductive material or an inner face with conductive paths which function as rotor windings.

    Abstract: A rotating electric machine comprises an armature arrange opposite the periphery of a magnet which is rigidly fitted to a rotary shaft. The armature has a plurality of salient poles arranged on it and projecting towards the magnet. The machine is characterized in that the surface of each of the salient poles facing the magnet comprises bevelled areas arranged at the lateral ends thereof and the magnet is a hollow cylindrical ring magnet. With such an arrangement, its induced voltage can show a sustained sinusoidal waveform which is free from high harmonics to an extent greater or equal to that of a rotating electric machine comprising a segmented magnet and consequently the level of cogging of the inventive machine can be minimized. If the ring magnet of a rotating electric machine according to the invention is skewedly magnetized relative to the axis of the ring magnet, the effect of the machine in maintaining the sinusoidal waveform of the induced voltage can be further enhanced.
