Abstract
An electrical machine, in particular an electric motor, has a first number (k) of commutator laminates () and brushes (), wherein the commutator laminates () are arranged distributed uniformly in the circumferential direction of a circumference of a laminate support (). The brushes () 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 () which is less than a number of poles () in the electrical machine.
