Motorized drum shell arrangement

摘要: A motorized drum having a shell with motor therein, the stationary shaft, stator windings, and support structure that is affixed to shaft. rotor rotates coaxially around stator, cycloidal reducer has an output at reduced rate. The rotationally fixed to, disposed within, shell. An input gear of received hollow eccentric urged into motion as shaft rotates. urges rotation same rate gear. harmonic drive speed provides rotatory wave generator against flexible splined member. member engages rigid circular spline two radially opposed zones. Induction permanent magnet forms operation are used.
