Abstract: The invention relates to an electrical machine with a stator (1) and a rotor (2), it being possible for the rotor (2) to be moved in rotary fashion with respect to the stator (1), and the stator (1) having slots (4), in which conductor loops (6) of a winding for electrically inducing a magnetic field are arranged, and the rotor (1) having slots (7), in which conductor loops (9) of a winding or cage bars (9) are arranged. Against this background, the invention specifies an electrical machine in which the disruptive noise emission can be reduced significantly whilst maintaining approximately the same performance data for the machine. For this purpose, provision is made for the slots (4, 7) of the stator and/or of the rotor to be spaced apart from one another nonuniformly over the circumference of the stator (1) or the rotor (2).Furthermore the invention specifies a process for manufacturing such an electrical machine.
