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.
