Hi all,
I have a question (I'm a newbie).
In my arduino starters kit, there is a DC motor. On that DC motor, on the axis, there is a star shaped form on which you can add fe a little wheel. In that little wheel there is a star-shaped form cut out that fits the star on the axis.
Now, I have bought 2 new DC motor, but on the axis there is nothing on which I can attach something.
In my project, there should be 2 wheels (diameter 25 cm) attached, but I don't know how.
Somebody have an idea?
Thx
If you intend to use the motors as a traction drive system you may be disappointed by their performance. Traction motors should run at around 100RPM or less and the motors you illustrate will run at several thousand RPM. You need a motor with a gearbox on the end to reduce the their speed.
Once you find a suitable motor you either need a traction wheel that fits the shaft or you need "bushes" to couple the shaft diameter to the wheel bore.
It sounds like your original motor has splines on the motor shaft to get a grip on the matching splined gear wheel.
Most small motors have smooth shafts and with the small torque involved a tight push fit is often sufficient. If that is not sufficient you need to get a wheel with a bush that has a screw to clamp it to the shaft. You could also try glue such as Loctite - but be warned - it can be very near permanent.
