A motor for use with an alternating current electrical outlet includes a retaining member, a rotor and a nutational actuator for nutating the rotor. The retaining member has at least one circumferential surface extending about an axis. The rotor is located adjacent to the retaining member and includes a magnet. The rotary actuator includes at least one magnetic member proximate the rotor, an electrically conductive coil about the at least one magnetic member and a plug having first and second prongs electrically connected to first and second ends of the coil. When the prongs are inserted into the electrical outlet, the alternating current flowing through the coil causes the rotor to nutate about the axis defined by the retaining member. In one exemplary embodiment, the rotor has a center of mass such that the rotor gyrates about the center of mass in response to alternating electrical currents flowing through the coil. In one exemplary embodiment, the retaining member is formed from a non-magnetic material and is integrally formed as part of a single unitary structure with a body supporting the magnetic member. According to one method, the motor is formed by providing a magnetic member having an axial end; wrapping an electrically conductive coil about the magnetic member, wherein the magnetic member has first and second opposite ends adapted for being connected to a source of an alternating electrical current; molding a mass of non-magnetic material about the magnetic member and the electrically conductive coil to form a body; forming a retaining member having an axis within the body proximate the axial end of the magnetic member; and positioning a rotor along the axis of the retaining member.
