A motor apparatus having a rotor that includes one or more permanent magnets disposed in ring-like manner, wherein similar poles of adjacent magnets face one another, and further wherein a gear mechanism (e.g., a toothed ring) is configured to transfer rotation from the rotor to an external gear mechanism. The motor may also include a stator comprising one or more solenoids and a bearing assembly that includes a rotating bearing element integrated with a toothed element for engaging with a gear and axle assembly. The rotating bearing element and integrated toothed gear element may pass through cavities of the main solenoids and provide for minimal cavity size, improving motor efficiencies.
