Electric motor configurations are provided with Halbach arrays. In one example, an electric motor includes a first plurality of magnets arranged in a first Halbach array. The first plurality of magnets is configured to provide a first magnetic field that substantially exhibits a first Halbach flux distribution. A first plurality of electromagnets comprising a first plurality of coils are arranged in a second Halbach array. A controller is adapted to selectively direct current through the first plurality of coils to induce a second magnetic field to interact with the first magnetic field. The second magnetic field substantially exhibits a second Halbach flux distribution.
