Claim Text:
1. An electric machine, comprising: a primary section; a secondary section interacting with the primary section via an air gap during operation of the electric machine; and a first base element fastened to the secondary section and including a first pole shoe having a first end and a second end, with the second end of the first pole shoe facing the air gap, a second pole shoe having a first end and a second end, with the second end of the second pole shoe facing the air gap, and a permanent magnet disposed between the first pole shoe and the second pole shoe so as to connect the first pole shoe and the second pole shoe with one another and having a magnetization from the first pole shoe to the second pole shoe, said permanent magnet having a matrix with a magnetically active material embedded therein, wherein the permanent magnet is arranged to separate a first region of the base element and a second region of the base element from one another, said first pole shoe comprising the first region with magnetically soft properties and a magnetic permeability index of μ wherein each of the pole shoes have connections which protrude into the permanent magnet, connect each of the pole shoes with the permanent magnet, and are configured to prevent a displacement of the permanent magnet parallel to each of the pole shoes and perpendicular to each of the pole shoes, wherein the connections of the first pole shoe and the connections of the second pole shoe are located opposite to one another in a perpendicular direction, and wherein the connections of each of the pole shoes include a T-shaped connection and a straight perpendicular connection.
