Hello all..
I'm designing a project and I want to implement a higher torque motor. to be connected to a pulley system, to slowly pull and release a rope.
I don't have a lot of equipments in my area, but there is this 36v 24" linear actuator usually used to adjust the direction of satellite dishes. Not a lot of data about the motor, although the dish the actuator pushes is heavy.
Here is where I need someone with mechanical engineering background... assuming that the actuator can lift and release 20lb when it contracts and extend. If I remove the arm and shaft, and install a wheel in its place, so that instead of the motor assembly rotates the actuator shaft, it rotates the wheel for the pulley. Will I can still lift the same weight? if I'm going to lose power, How much % will I lose? (try to ignore gravity force).
I know that it's hard to answer without enough info on the actuator and its motor, but I just need an in-theory answer.
Also, if anyone have an idea on how much torque do motors of DC linear actuator in this range have, please share.
Thanks in advance.
