Hi All,
I have a project which involves pulling a sled (wheeled, on rails - low friction) weighing approximately 15kgs over a set distance and time. The distance is approx 60cms and the duration is 3 days.
To minimise cost I intend to anchor a motor(ac or dc)/gearbox combination and use a take up spool to "reel in" the sled.
I've calculated that a 2cm diameter spool will need 9.5 revolutions, a 3cm spool 6.5 revs and a 4 cm spool about 5 revs - over 3 days!
Where I need help is what motor and gearbox/es will I need to achieve this?
The time and distance doesn't need to be exact, I reckon distance can be +/- 5cm and time can be +8 hrs.
To save cost I'd like to be able to leave out a controller, ie run the motor straight from battery or mains - preferably battery.
I'm starting from scratch so anyone with suggestions for off the shelf components please let me know.
Otherwise I guess I need to know what speed motor at specific voltage and what gearbox/es to attach to it.
Sorry for my ignorance!
Any help/advice much appreciated.
