摘要:
When one of armature coils (9, 9a, 9b) is in a beginning of a commutation process, a center line of a trailing end tooth (12b, 12d) of a corresponding group of teeth (12, 12a, 12b-12d), around which the one of the armature coils (9, 9a, 9b) is wound, is generally aligned with a corresponding boundary between magnets (2, 3). When the one of the armature coils (9, 9a, 9b) is in an end of the commutation process, a center line of a leading end tooth (12a, 12c) of the corresponding group of the teeth (12) is generally aligned with another boundary between the magnets (2, 3).

. This invention relates to armatures of tradi- tionalDC rotary machines which are generally furnished with either lap windings or wave windings, no matter which one of these two types of windings are furnished, the ending lead of the whole windings will return to its starting lead to form a closed loop. Therefore, it is impossible to use these traditional winding technics to construct a limitless extending non-closing armature windings for a DC rotary machine. The object of the present invention is to provide a novel limitless-extending non-closing armature coil winding technic for DC machine through the utilization of two wned bidirectional conducting effect.

The invention relates to a brush-commutated direct-current motor comprising: a stator having a plurality of excitation poles; a rotor, which can be rotated about an axis of rotation in relation to the stator and which has a plurality of pole teeth, grooves arranged between the pole teeth, and coil windings arranged on the pole teeth; a commutator, which is arranged on the rotor; and a plurality of commutator bars, to which the coil windings are connected. In order to produce such a direct-current motor, the coil windings are arranged on the pole teeth in winding revolutions, in which a coil winding is wound on each pole tooth. According to the invention a first coil winding (Z1l-Z9l) wound around the pole tooth (Z1-Z9) in a first winding direction and a second coil winding (Z1r-Z9r) wound around the pole tooth (Z1-Z9) in a second winding direction opposite the first winding direction are arranged on each pole tooth (Z1-Z9), wherein in a first winding revolution the first coil windings (Z1l-Z9l) are wound on a first share of the pole teeth (Z1-Z9) and the second coil windings (Z1r-Z9r) are wound on a second share of the pole teeth (Z1-Z9) and in a second winding revolution the second coil windings (Z1r-Z9r) are wound on the first share of the pole teeth (Z1-Z9) and the first coil windings (Z1l-Z9l) are wound on the second share of the pole teeth (Z1-Z9). In this way, a method for producing a brush-commutated direct-current motor is provided which makes it possible to produce the direct-current motor in a simple manner in which the available packaging space is fully utilized.

Die Erfindung betrifft einen Elektromotor für das Elektromotor-Pumpen-Aggregat eines Kraftfahrzeug-Antiblockiersystems. Dieser Motor weist einen Stator und einen Rotor auf. Der Rotor enthält Rotorzähne und eine exzentrische Abtriebswelle. Die Verteilung und/oder Dimensionierung der Rotorzähne ist dergestalt, dass der Verlauf des Motordrehmoments dem Verlauf des Lastmoments phasengleich folgt und das Motordrehmoment zu jedem Zeitpunkt einer vollständigen Umdrehung der Abtriebswelle größer ist als das Lastmoment.
