I’ve tried searching the forums for this, but the search function doesn’t allow for phrase searching to narrow down results.
Here’s my dilemma,
Is there a way to purchase motors (DC brush, or any other kind for that matter) and EASILY find the connectors, couplers, shafts and wheels etc for THAT particular motor.
I’ve purchased some radio shack motors and I’m having the darnest time extending the shaft and matching stuff to it. I’ve purchased some wheels which were SUPPOSED to have the same size bore but in reality they didn’t.
I’m I stuck with trial and error, or is there a better way?
These motors are fine, but I’d like to try some others just for experimental purposes. For example, I’d like to try using this motor in the same application, but like the RS model, it doesn’t specify shaft size, so I’d be back to guesswork as to adapters, and shaft extenders:
It’s frustrating to order what you think you need only to wait a week and find that the parts don’t quite match. Then it’s back to the guesswork and finger-crossing.
I didn’t realize it was a common issue. I was sure I was missing something simple.
I think you have a monumental task in front of you to make a tool to solve this.
I figured I could push the motor shaft (2.3mm) into the 2mm hole, or heat the shaft and melt it in. Hopefully I’d get it on straight because at 18k rpm I’d be in trouble if it was crooked. But the bigger issue is the 2mm hole is on the same side as the hex protrusion to attach the wheel.
So how would I attach the wheel?
Methinks there is a more straighforward solution, but I can’t seem to find it on the site.
(I don’t want to gear down the motor - I need the highspeed)
Well I guess the search feature didn’t dig up exactly what I was looking for. Close though.
I’m looking to use a motor with a round 2.3mm motor shaft to connect to a square 2.3mm VEX wheel. Is there an adapter readily available or am I gonna have to get creative?
This has been a major issue which many people have in robots (and not just for mechanics). We have heard you and we are working on a tool which may revolutionize the way you make a custom robot. Until then however, what are you trying to do - what’s the shaft size? We’ll do our best to give you some options.
VEX does not produce any adapters, so the closest you may be able to find is a shaft coupler of exactly the same diameter as the diagonal measurement of the VEX square shaft (or drill it out yourself). We don’t sell any adapters of this kind.
The wheel you suggest uses a 2mm double flat hole for mounting. If you need this wheel and a motor with a slightly larger shaft (and double flats) then you can simply sand down the shaft a little bit (turn the motor ON and apply some sand paper).
