Hi,
this motor topic confues me hard.
Can someone tell me the latest recommended DC motor, which is replacing the Phidgets. Idealy including a link also to the driving wheel.
Unfortunately the linkes from Juurikko are not aktive anymore.
Where can i find basic holder which can be adapted ?
Thanks for your help.
Why would there need to be a new recommendation to replace the Phidgets motor?
Since the price is very high compared to a China replacement and the availabilty is poor in EU
Price could always be lower. Seems to be available at the same shop where I bought mine a long time ago:

Is the China replacement and equivalent motor, exact same specs? If yes, then no need to change the motor recommendation (the recommendation is for the part, not for a particular shop).

But both phidgets are a steal
Just the EZ motor and terrain compensation box without tax or shipping are what I paid in total for all of AgOpenGPS.
there is also this one, which I have used several times and which works very well. arrives between 15 days and 1 month.
I use the one in 12v 5.2-950Rpm
Thanks guys, this helps.
Where can I get a rubber transmission wheel for the phidgets?
you can try to print in TPU
but try to use stronger center because 12mm shaft is too week agains the torque for TPU
These wheels have 12mm shaft you can drill out center and get it on motor and you need flange coupling that have screws or cutout slot hole to use slot that you get with motor.
If you can print then go for gear system, there is no slippage, looks better.
For motor in AOG fashion 12V battery drill but as many found out you go out and buy a phidgets 3269_3 and have tested proven motor and one less thing to worry about in endless possibilities of settings and setups. Time, materials and work that has to be done for motor holder will be more then you save on cheaper motor with high risk of failure in autosteer rapid back and forth movement.
If cheap motor fails you have to replace it and 2x motors will cost as one phidgets and who says that it will not fail again. Or you will then buy phidgets and make new holder for it either way will cost more then going with good motor first time.
You can get lucky and cheap motor is actually good then you can post hire so others can use it. 
X2 on @PotatoFarmer ’s printed gears!! Not only does it look better, but it’s a much better utilization of space! No wheel slip either. Not to mention it’s an excellent excuse to buy a 3D printer!
Thanks @Damnbuffalo
In the gear vs tire debate, gears take much less force to stay engaged, and as its been said the no slip gives no surprises, and the wheel is completely free no pinch point, no flat spots either.
But the greatest part of AOG is its never finished unless you say it is, you can always revisit or change a mounting bracket or control type at a later date. For your first build just do whatever it takes for completion. Amazing how much more build planning can happen when you are not driving.
I bought hubs from Phidgets that fit their motor. Then as a proud Canadian I use hockey pucks as the wheels. Spring tension for friction and I’ve never had an issue with slipping.
Daniel, this one looks like the Phidgets motor. I did not find any stall current figure for it, is it safe for the usual AOG motor drivers, IBT and Cytron?
great idea
By the way: The official name of the Phidgets motor is:
60ZY105-2430 from Dongzheng Motor
Idea: Why not bypass the 12 V to 24 V converter during line operation and running the motor with full power during u-turn?
Just to more relais or transistors are required.
Another approach could be designing a voltage-boost-converter with digitally controllable output voltage (maybe 4 steps between 12 V and 24 V).
However the complexity of the controll loop will increase.
Just to think about.
No need to bypass the 24v, more torque is better for small adjustments.
First phidgets movement happens at 30pwm at 24V with no load.
Did anyone tried to use electric steereng from car for motor?Seems to me it has speed and power as needed.
I have it on my corsa c , and even it has no power stereeg wheel goes easy.
Do you think the Corsa power steering motor would be less expensive than the ones that are mostly used here? Do you think it would be mechanically easy to install to turn your steering wheel. I assume you do not want to use it to directly steer tractor wheels.
Honestly, the most common motor can be purchased quite cheap. I don’t see any point spending time on other options. Support from the forum gets scattered when so many different components are being used.
I understand real experts playing with parts for different reasons but they don’t need to count on forum help if they face issues.
