Abstract
A gear motor for decreasing speed at a mechanical power output is provided with a housing; a supporting shaft disposed along an axis of the housing and fastened in the housing; a planetary gear train as a speed reducer which is rotatably supported by the supporting shaft; and an electric motor including an outer stator and an inner permanent magnet, the electric motor disposed around the planetary gear train and within the housing. The planetary gear train includes a stationary sun gear secured to the housing and coaxially disposed around the axis of the housing; a driving sun gear as a torque output; planet gear assemblies equally spaced around an outer surface of the stationary sun gear. Each planet gear assembly includes coaxial first and second gears; and a carrier pivotably supported by the supporting shaft and attached to the permanent magnet.
