Does anybody know of an equation or rule of thumb for power decrease as load increases?
As an example an electric golf cart will go say 15mph with one 100lb driver. Put 4, 200lb people in it and it will go much slower, say 9mph. Is there a way to determine what that loss will be other than simple observation?
Does an electric motor's efficiency rating play into it? One motor I am lookng at is 86% efficient. Does that mean 86% of the incoming electrical power is converted into mechanical power? If so, is that under no load conditons or some sort of industry standard load?
Thanks
