Abstract
An electric motor has a switching unit with a number of contact wires and an annular frame part. The contact wires are arranged to form an interconnect ring for the coil ends of a stator winding and the ends of the wires being connected by insulation displacement contacts. Each of the contacts have two insulation displacement limbs for connecting at least two of the wire ends, the limbs being spaced apart, thus forming an insulation displacement slot therebetween. The frame part of the switching unit has a number of plug-in pockets for receiving the insulation displacement contacts, the number corresponding to the number of insulation displacement contacts.
