Patent ID: 6891289

Claim:
An electric motor comprising: a housing, at least one rotor provided with magnetized regions and mounted rotatably about a rotor axis in the housing, and a stator having at least one stator unit, each of said at least one stator units including a set of first pole shoes, formed as claw poles, and a set of second pole shoes, formed as claw poles, said first and second sets of pole shoes being disposed around the rotor axis, a coil positioned following the rotor in the direction of the rotor axis and with coil windings arranged to encircle the rotor axis for magnetizing the first and second pole shoes, each of said at least one stator units having two pole shoe elements: a first pole shoe element having a first pole shoe carrier which extends transversely with respect to the rotor axis and is disposed on a side of the coil facing the rotor, the first pole shoes formed integrally onto the first pole shoe carrier such that the first pole shoes extend away from the first pole shoe carrier in a first direction approximately parallel to the rotor axis, and a second pole shoe element having a second pole shoe carrier which extends transversely with respect to the rotor axis and is disposed on a side of the coil facing away from the rotor, the second pole shoes formed integrally onto the second pole shoe carrier such that the second pole shoes extend in the first direction away from the second pole shoe carrier approximately parallel to the rotor axis beyond the rotor, the first pole shoe element carrying a connecting element which is formed integrally onto the first pole shoe carrier and establishes a magnetic circuit between the pole shoe carriers, the connecting element being fixedly connected to the second pole shoe carrier, the second pole shoe carrier is connected to a bearing support which carries a rotary bearing for the rotor; and a receiving portion of the bearing support engages into the connecting element.
