摘要： An electrical machine, in particular an electric motor, has a first number (k) of commutator laminates (10, 12, 14) and brushes (16, 18), wherein the commutator laminates (10, 12, 14) are arranged distributed uniformly in the circumferential direction of a circumference of a laminate support (24). The brushes (16, 18) are arranged such that commutation times are distributed as uniformly as possible in order to reduce current ripple when using a wave winding and a number of brushes (16, 18) which is less than a number of poles (2p) in the electrical machine.

A commutator has a plurality of segments arranged in the circumferential direction and a short-circuit conductor for short-circuiting predetermined segments from among these segments.

摘要： Systems and methods for electrical component, e.g., brush, manufacture are provided that control grain orientation. The systems and methods utilize hot pressing techniques to enhance the properties and functionalities of the electrical components/brushes. An intermediate work product characterized by a grain orientation is initially formed through a conventional pressing technique. The conventionally-pressed intermediates are positioned within a cavity/die with the grain orientation in a predetermined orientation relative to the hot press force to be applied thereto. The hot pressed final product exhibits superior resistivity, strength and apparent density/durability. Surface features may be formed on the face(s) of the final work product during the hot pressing step that cannot be achieved in conventional processing techniques. Advantageous articles of manufacture, e.g., brushes and brush assemblies, are also disclosed.

摘要： In an AC generator of a motor vehicle, having a positive polarity brush from which current flows into a corresponding slip ring and a negative polarity brush into which current flows from the corresponding slip ring, the brushes or the springs of the brushes are configured respectively differently, to achieve substantially identical rates of wear for the brushes. This is done for example by increasing the area of contact between the negative polarity brush and its slip ring, lengthening the negative polarity brush, or decreasing the amount of force applied by the spring of the negative polarity brush.

摘要： A direct current electric motor brush and brush housing arrangement, comprising means to significantly reduce the effect of brush lift in a brushed motor containing viscous fluid. The means enable viscous fluid to avoid momentum transfer into the brushes by providing two or more pressure relief channels that provide the fluid with direct means of radial exit along the direction of the brush, potentially reducing the brush lift due to the fluid being forced between a rotating commutator and its associated brushes. The pressure relief channels may be located in the housing immediately adjacent to the brush, being radially disposed to the leading face (or leading and trailing faces) of each brush, or in the leading face (or leading and trailing faces) of each brush itself, and may comprise additional channels in the housing near but not immediately adjacent the brushes.
