摘要： The invention relates to an electric machine (10) and to a method for operating the same, especially for power-adjusting movable parts in the motor vehicle. The electric machine comprises a stator (34) and a rotor (18), grooves (24) being configured on the rotor (18) in which grooves individual conductor loops (36) of electrical coils (30) that contact commutator bars (22) of a commutator (20) are arranged, and an evaluation unit (40) that determines, based on the ripple of the motor current signal, information on the rotational speed. The invention is characterized in that the number of the individual conductor loops (36) of the coils (30) is selected in such a manner that the sequence of the number of conductor loops (36) in the order of their commutation is approximately a sine function (60).

Continuous application of the direct current voltage across the brushes (150, 152) causes the current to flow in a varying number of the current conducting windings (166, 168, 170, 172) as the commutator (154) continues to rotate, the number periodically varying from all of the current conducting windings (166, 168, 170, 172) to the at least one current conducting winding (166, 168, 170, 172).
A closed-loop control system is also disclosed that includes a direct current voltage source, a direct current motor (100, 146, 216) including an imbalanced winding and a shaft (106), a motor position signal source (36) that generates a motor position signal for rotating the shaft (106) of the direct current motor (100, 146, 216) to a desired position, and a feedback circuit (214) that corrects for any error in the desired position of the shaft (106) of the direct current motor (100, 146, 216).
A printing mechanism (20) having a direct current motor (100, 146, 216) that generates a position feedback signal is additionally disclosed.
Further disclosed is are methods (224, 238) of controlling a position of a shaft of a direct current motor in a closed-loop feedback control system (224, 238), the motor having an imbalanced winding.摘要翻译： 在闭环控制系统中使用的直流电动机（100，146，216）是圆盘游离缺失确实包括具有狭槽（156，158，160，162，164）的多个A旋转换向器（154），的多元 绕组（166，168，170，172），绕组的数量没有传导电流对应于一个小于槽的换向器（154）的数目（156，158，160，162，164），和刷子的多元性 （150，152）确实为跨电刷那样的直流电压的施加被配置（150，152）导致在绕组（166，168，170，172）中的至少一个（其导致换向器的电流流动 154）旋转。 穿过电刷（150，152）的直流电压连续施加使电流在不同数目的电流传导绕组（166，168，170，172）作为换向器（154）的流动继续旋转时，数 从所有电流传导绕组（166，168，170，172）到所述至少一个电流传导绕组（166，168，170，172）的周期性变化。 闭环控制系统因而盘游离缺失确实包括直流电压源，包括在不平衡的绕组的直流电动机（100，146，216）和轴（106），一个电动机位置信号源（36）做基因率 为直流电动机（100，146，216）的所述轴（106）转动到希望位置的电动机位置信号，和一个反馈电路（214）那样校正了的所述轴（106）的所希望的位置的任何误差 直流马达（100，146，216）。 具有直流电动机（100，146，216）做了打印机构（20）生成一个位置反馈信号被另外游离缺失盘。 此外游离缺失盘IS是控制在闭环反馈控制系统（224，238）的直流电动机的轴的位置的方法（224，238），其具有以不平衡的绕组电机。

摘要： Lower-layer coil ends (537) and upper-layer coil ends (534) forming the first and second connecting portions are held in abutment with the end face of an armature core (500) through insulators and, hence, the inertias of cylindrical commutators and armature coils in the prior art are reduced to reduce the inertia drastically as that of the armature (540). As a result, while a pinion gear (210) is meshing with a ring gear (100), the impact torque at the time of inertial rotation can be reduced to reduce the module of the used gear to M = 0.9. At the same time, the reaction force R1 of the armature bearing (570) can be reduced by the weight of the cylindrical commutator of the prior art, and its support distribution can be reduced to l'/L', as compared with the value l/L of the prior art, to reduce the diameter of the bearing. As a result, a sun gear (310) can have its tooth number reduced to Zs = 8 (i.e., the deddendum diameter of Ζ = 5.85), and the speed reduction ratio can be set to I = 8.25. Hence, the motor volume can be reduced as compared with I = 6 or less in the prior art, so that the motor can be small-sized.

摘要： The provision of an electric rotating machine which can reduce the mechanical and thermal loads applied thereto. Coil arms (534, 537, 20b, 21b, 20d, 21d) and coil trunks (533, 536, 20e, 21e) are provided in roughly parallel orientation to the end faces of an armature core (520, 11) only through insulating rings or spacers (560, 590, 20a, 21a, 20c, 21c). Metal brush (910, 81) is disposed on coil arms, whereby the overall length of the armature can be remarkably shortened. In addition, a commutator, conventionally necessary, can be eliminated, whereby the length of the production process for the armature can be reduced. Moreover, in an arrangement where projections (534c) of the upper coil arm are fit in holes of the insulating spacer, as the displacement of the upper coil arm towards the outer periphery is regulated, the length of axial protrusions of the upper coil arm from the end face of the armature core can be minimized. In addition, as extension portions (538, 20g, 20h) and of the coil trunks are strongly pressed against and fixed to the side of armature core by fixing members (570, 30), the resistance to the centrifugal force can be remarkably improved. Furthermore, as the extension portion of the lower coil arm is fit in a recessed part of the insulating spacer, the displacement of the lower coil arm in the axial direction towards the outer periphery can be prevented.

摘要： Disc-type motor characterized by increased efficiency. The motor has two parallel spaced stator members (30, 32) each having a flat circular shape and an even plurality of pre-segmented permanent-magnet poles (34) in a circular array thereon, illustratively eight in number. The facing poles of the stator members have opposite polarities. The motor includes a disc rotor (28) made of a non-conducting material rotatably mounted between the two stator members. Conducting wires are wound to form a number of coils (29) in a circular array on each face of the rotor. The number of coils on each rotor face is greater than the number of poles on each stator member, and each coil (29) occupies an arc sector area smaller than the area of each stator pole (34). The coils (29) arrayed on one face of the rotor (28) are angularly offset from the coils on the other face of the rotor. The includes a commutator (44) connected to the rotor (28) which has a number of segments corresponding to the coils of the rotor.
