摘要： 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.
摘要翻译：为了尽可能减少由于在电枢线圈中感应的感应电动势波形中包含的谐波分量的影响而引起的电动机振动。在电动机结构中，通过改变它们的面积或歪斜量，使得单极齿和构成一相的对应极齿的极齿形状彼此不同，由此由与磁铁相互连接的磁通量的变化引起的三次谐波使这些极齿相互抵消。因此，可以降低迄今为止存在的问题的旋转振动，并且还可以在不降低电动机的动态转矩特性的情况下提高转子运动的精度。

摘要： A motor structure including a rotor 1 having a permanent magnet 10 where north poles and south poles are alternately disposed in a moving direction of the rotor, a stator 5a including at least two stator yokes having stator pole teeth 3a, 4a respectively which face to the permanent magnet at a distance and are respectively positioned side by side in the moving direction to bear north poles or south poles respectively due to an electric current flowing through a coil 2a to thereby form at least one phase, wherein the stator pole teeth 3a, 4a are different from each other with respect to an effective area through which magnetic flux passes, whereby high harmonic wave phases generated from the pole teeth 3a, 4a are different from each other by 180 degrees in electric angle to thereby be canceled mutually, therefore an induced electromotive force wave containing hardly high harmonic wave is obtained to thereby reduce a motor vibration.

摘要： A claw pole type synchronous motor has two cylindrical stator assembles arranged back-to-back and a magnetized rotor provided coaxially with the stator assemblies. The rotor has a length larger than the total thickness of the stator assemblies and always covers the inner peripheral surfaces of the stator assemblies so as to reduce vibration due to axial movements of the rotor with respect to the stator assemblies. The motor also has an electrical phase angle defined between the center lines of the corresponding claw poles of the adjacent stator assemblies made equal to the theoretical electrical phase angle minus an electrical angel within a range more than 0.degree. and less than 10.degree..

摘要： A rotary electrical machine has a mechanism capable of varying an output characteristic, without increasing mechanical loss, or without consuming the electric power that does not contribute to increasing torque. The rotary electrical machine has a rotor with N pole and S pole magnets alternately and fixedly disposed thereon. An end surface, (which opposes the rotor), of each of a plurality of first teeth positioned on a first stator section is broader than that of the opposite surface thereof, and a winding is wound around a portion between both of the end surfaces. A second stator section has second teeth, corresponding the number of the first teeth, and which has no winding. The second teeth are disposed to oppose the end surfaces of the respective first teeth, and each second tooth is reciprocally movable between a reference position at which the second tooth directly opposes the respective first tooth and a maximum movable position located at the right center position between the respective end surfaces. At the reference position, a strong magnetic flux flows into the entire first tooth from each magnet. At the maximum movable position, a weak magnetic flux flows over the end surface of each first tooth. A middle amount of the magnetic flux flow occurs at a middle moved position.

摘要： A rotary electrical machine includes a rotational shaft supported by a housing for rotation about an axis, a rotor coupled with the rotational shaft, and a stator fixed to the housing and oriented to face the rotor. A rotor position changing mechanism moves the rotor in an axial direction of the rotational shaft using a portion of a torque transmitted between the rotational shaft and the rotor as a driving force. The rotor position changing mechanism controls the strength of the magnetic field between the rotor and the stator by moving the rotor toward or away from the stator.

A tooth 61 is mounted to a stator yoke 60 in a state in which at least part of it (a portion 81 to be inserted into the yoke) is inserted into an insertion hole 75 formed through the magnet-opposed surface of the stator yoke 60, and the cross-sectional area S1 (See FIG. 6A) of the portion 81 of the tooth 61 to be inserted into the yoke, which is taken perpendicularly with respect to lines of magnetic force B1 generated at the tooth 61 when a coil 62 is energized, is larger than the cross-sectional area S2 (See FIG. 6B) of the portion 82 to be disposed within the coil of the tooth 61, which is taken perpendicularly with respect to the lines of the magnetic force B1.
