A rotating stand assembly (10) for a stemmed article such as a Christmas tree (24) or a merchandise display rack includes a base (12), a spindle (18), bearings (36, 38) interconnecting the base (12) and the spindle (18). An electric motor (46) drives the spindle (18) through a gear train. A clutch (58) automatically disconnects the motor (46) from the spindle (18) in response to a predetermined force applied to the spindle. The clutch (58) includes a compression spring (78) for establishing the predetermined force required to disconnect the motor (46) from the spindle (18). Snap-fit outlets (86) are located in a top cover (32) of the spindle (18). The outlets (86) are electrically connected to contact rings (90, 92) without solder. A limit switch (84) can provide and audible warning that there is an obstruction to normal operation. A live tree adapter (106) is placed into the spindle (18) to accommodate a live Christmas tree (24).
