So, I'm not an expert on electric motors. I have yet to take a formal class on electric motors. But I am however in a position where I'm required to size a couple electric motors for a project.
I've been using software that is supposed to help size motors depending on the application and I recently came across something that I can't explain.
Specifially, I found the amount of power that was required to move a mechanical load. This ended up being around 10 Watts. However, this load had a high torque but moved rather slowly which is what lead to the low calculated power. But when I tried finding a suitable motor, the program was offering motor solutions of 3 to 4 kWs.
This made no sense to me. Why would a 10 Watt load require such a high powered motor? I then realized that because the torque was so high, this meant there would be a large current associated with it. I interpretted this as if only high powered motors could handle this high of current, so that's why I was bumped into that range.
But I'm still not happy with this answer. Could anyone explain this to me?
