Hi, I’m new to this please forgive my novice questions. I’m building a belt driven linear elevator for lifting canned beverages up a tube from my basement to my beverage center. Take a Coke off the countertop lift and another one lifts up to replace it (think electric PEZ dispenser). I need to find the right motor and belt. It will be lifting 20 lbs. but I could counter balance that mostly with a spring or surgical tubing if needed. My big question is the “holding power” of any particular motor. When stopped, I need the motor to passively lock and resist approx. 5 lbs. of weight on the belt (ideally 20 lbs. if I can get away without counter balancing it). How are motors rated for this “locking torque” or whatever the term is? Any advice would be appreciated.
Thanks,
Scott
Hi Scott,
There are a lot of different ways to do that.
If you design allow for it, you could use a linear actuator which is made to handle static weight.
Thank you for the idea Eric. The total travel distance will be 11’ so I don’t think a linear actuator will be practical.
Best,
Scott
That made me laugh, you are right at 11’ it will be a looong actuator.
We do not have belts that long either but you may be able to work with a MXL type pulley and belts.
MXL 60 Tooth Timing Pulley
It has a 6mm bore so many motors will fit.
Try the Cytron brand as they are very good for the price:
