My concept of spin is using 2 wheels with the ball sandwiched in between and when the 2 wheels have different speeds the ball shall come out having some spin to it. This 2 wheel solution is a good approximation of a 2D spin model. But if you want to provide spin in 3D like a top spin/bottom...

Yes exactly, but the with a lighter cricket ball of about 70-100gms instead of a 150gm baseball.

Hi, thank you so much for your help. I'm indeed working with 2 wheels but calculated with 1 wheel to keep things simple as i figured that if calculations show that it works with 1 wheel then it sure shall work with 2. Well, my inspiration of the metal plate came directly from this stuffmadehere...

I have designed the control electronics to detect the moment of the energy transfer and immediately cut off power(the motor stops immediately) and after the ball is launched they spin up again. Or I can also do the motors spinning at a constant RPM throughout. I'm asking for advice about what...

Assume the top image to be the simple version of the wheel configuration and the lower one to be the proposed way of wheel arrangement. In the newer version i want to use a heavy metal plate of approx 200gms and a wheel of 50gm instead of a heavy 200gm wheels due to sourcing issues. This is...
