An electrically and mechanically driven automotive accessory including a housing, an electric motor, a pulley, and a pulley assist mechanism. The electric motor comprises a stator assembly that is mounted to the housing and a rotor assembly that is mounted to a shaft. The electric motor creates a primary torque flow path that drives rotation of the rotor assembly relative to the stator assembly. The pulley is rotatable relative to the shaft and the rotor assembly. The pulley assist mechanism includes an annular channel in the rotor assembly that creates a magnetic gap, a finger made of a non-ferrous metal that extends from the pulley into the annular channel, and an electromagnetic coil that induces eddy currents in the finger of the pulley and a magnetic field in the magnetic gap, which creates a secondary torque flow path between the pulley and the rotor assembly.
