I have just sized the DC motors I want to use (corresponding to my robot and its intended applications - my figures include a 50% uncertainty factor to account for friction in reducers and other losses). Now I need to actually choose the exact motors I want to buy from the manufacturer (I am targeting maxon motors as I am not an expert and want no problem). I have a few down to earth questions about linking the mechanical needs to the electrical characteristics, among them:
I chose a motor reference (310005 maxon reference found here) which has a stated power of 60W, as the nominal voltage is 12V, I was expecting to have a nominal current of 5A, but it states 4A. Where am I wrong?
