Abstract

An electric machine of a motor vehicle, in particular of an adjustment drive or of a radiator fan, has a rotor which is mounted so as to be rotatable about a machine axis. The rotor has a number of permanent magnets which are arranged in the radial direction. Each permanent magnet has one side with a strong magnetic flux and one side with a weak magnetic flux in the tangential direction. When the permanent magnets are adjacent in the tangential direction, different sides are directed towards one another.
