ABSTRACT:
A power assembly for rotating a display is simple, inexpensive, has long life, and can rotate even heavy displays. A housing mounts a d.c. motor having an output shaft, and has a support structure. A ball bearing assembly, having a second shaft, is stationarily held by the support structure, and a flexible tubular connector interconnects the motor output shaft and the second shaft. The display is attached to the second shaft by a flexible band of elastomeric material. An electronic circuit provides power pulses from a substantially constant d.c. power source (such as a bank of solar cells) to operate the d.c. motor.
