I was asked to post how to calculate power when you know torque and speed, so here we go. It's really simple.
The formula goes like this:
Power = Torque * Angular velocity
Torque ( in Nm )
Angular velocity ( in radians / second )
Power ( in Watt )
For example, I have a motor that deliveres 11Nm at 50 rpm (revolutions per minute). How much power can that motor deliver ?
First we convert from rpm to radians / second. 1 revolution equals 2*PI radians. 1 minute = 60 seconds. So 50*2*PI / 60 => 5.23 radians/ second
11Nm * 5.23 radians / second => 57,6 W.
