A stator assembly for an electric motor includes a drive plate, a first magnetic core and a second magnetic core. A first core slot is formed in the first magnetic core and a second slot is formed in the second magnetic core. The first and second magnetic cores each include two elongated members joined at one end by a base member which are defined by the respective core slots. The two elongated members extend from the base member substantially parallel to each other toward the drive plate. A stator coil is wound through the first core slot and the second core slot. An electrical current flowing in the stator coil generates a magnetic field about the stator coil that is absorbed by the first magnetic core and the second magnetic core to generate a magnetic flux in each of the magnetic cores that magnetically attracts the drive plate.
