Hello Everyone,
Im new to your forum and only have the most basic electrical background (home repairs, garage wiring, and an automotive electrical class). Im venturing into a new project, a motorized forward and reverse revolving chair. I have some preliminary ideas and sure could use some expert advice at this point.
Function:
The chair, upon manually pressing a button, is to rotate one revolution to the right and stop automatically. Then, pressing another button it is to rotate in reverse (left) one revolution and stop automatically. Each rotation should take about a minute. Weight capacity could be 200 pounds and as high as 300 pounds. Ideally the start-up should be pretty smooth and steady as it completes a rotation and a smooth stop.
Im thinking a low speed high torque motor with a worm-gear on it. This would drive a gear that is fixed to the shaft of a rotatable chair. Controlled by forward and reverse buttons.
Does this look like a job for a DC motor?
Which would be easiest and lower cost: using mechanical or induction limiters attached to the gear affixed to the chair shaft or would a 555 timer be better (would I need two, one for each direction?).
Attached is a crude line drawing.
Thank you for your time and ideas.
