摘要： The invention describes an electrical machine having an armature with armature slots for accommodating armature coils. At least one armature coil is formed from two coil elements which are arranged symmetrically with respect to one another in relation to an axis of symmetry, which runs through the center-point of the armature shaft. The coil elements are connected to two adjacent commutator laminates of a commutator. A first brush, a second brush and a third brush bear against the commutator in a manner such that they can slide. The second brush interacts with the first brush or the third brush. The third brush is arranged in relation to the two coil elements in such a way that, when the two adjacent commutator laminates come into contact with one another, the third brush and the center-point of the armature shaft form an axis which has an angle of 90 DEG−(180 DEG/number of laminates)−(180 DEG/3×number of laminates) up to 90 DEG+(180 DEG/number of laminates)+(180 DEG/3×number of laminates) in relation to the axis of symmetry of the two coil elements.

摘要： An improved electrical commutator which is particularly useful in a vehicle steering wheel system, includes sets of wire brushes or fingers on a first plate. The wire brushes or fingers contact plural co-planar rings on a second plate. The two plates rotate relative to each other. The wire brushes or fingers decrease the likelihood that any one of the sets will have a short circuit. Should any one of the wires bend, break, or come out of contact with its associated contact ring, there is a likelihood that at least several of the other wires will remain in contact. In addition, there are plural sets of wire brushes or fingers associated with each of the contact rings, again increasing the likelihood that the circuit will remain intact. In other features, the plural sets may be mounted such that circumferentially spaced ones of the sets face opposed directions. In this way, there is no difference in the resistance to rotation, or the quality of the electrical communication, when the wheel is turned either clockwise or counter-clockwise.
摘要翻译：在车辆方向盘系统中特别有用的改进的电动换向器包括在第一板上的一组电刷或手指。线刷或手指接触第二板上的多个共平面环。两个板相对于彼此旋转。线刷或手指降低了任何一个组将发生短路的可能性。如果任何一条电线弯曲，断裂或与其相关联的接触环脱离接触，则有可能至少几根其他电线将保持接触。另外，与每个接触环相关联的多组线刷或手指也增加了电路保持完好的可能性。在其他特征中，可以安装多个组，使得这些组的周向间隔开的组面对相对的方向。以这种方式，当车轮顺时针或逆时针转动时，耐旋转性或电气通信质量没有差别。

摘要： A liquid pump has a DC motor and a pump in a cylindrical casing. A pair of brushes are slidably contacted with a commutator of an armature while being biased by springs. The specific resistance of the positive brush is lower than the specific resistance of the negative brush to enable the voltage drop at the brushes to be decreased and motor efficiency to be increased without increasing commutator wearing speed. The biasing force provided by the spring biasing the positive brush is lower than the biasing force provided by the spring biasing the negative brush.
