I am in the design phase of a project I am wanting to undertake. A possible layout that solves several challenges would involve using the Gearbox Kit to rotate a vertically mounted channel, but I need to obtain very accurate and repeatable positioning of rotating channel. Could the gearbox kit be driven by a stepper motor? If so, what mounting configuration should be considered?
If the Hitec server must be used is it possible to obtain fractional degree control with it?
Hi severly.
These are not designed to be used with a stepper motor, but if you figure out some way to attach the smaller gear to your motor and can mount in inside the channel, it could possibly work. Sadly We don’t have a motor or the hardware needed to mount it to this kit.
These do have a potentiometer on them that you can wire into a modified Hitec servo for feedback. I can’t say how accurate it would end up being, but probably within a few degrees. (You’d have to try it and see.) You’d need a Hitec standard sized servo with a C1 spline and would need to modify the servo for continuous rotation and rewire it for an external potentiometer to use it with this gearbox kit.
Thank you for the reply. In this design I will need a fairly accurate positioning mechanism. The objects I am selecting will be on a ring spaced 2.4 degrees apart, so if I’m off by a degree I’m in the wrong spot. I was trying to see if I could mount the stepper outside of the channel and use a shaft extender to get the driving gear at the right position to mate with the hub gear. Also considering mounting the stepper to the side of the channel and either directly driving the hub gear if I can position it correctly, or use a timing belt to transfer motion to the hub gear.
