This isn't exactly related to the Prius but I kinda need the answer for a project. Maybe there are electrical guys here that can help.
Is there any way to reduce the power output of a motor?
If a 5 HP motor is used to drive a load but when the load drops to a point where only 2 HP is needed. Is there a way to reduce the motor output to 2 HP? Or does the motor still runs at 5HP regardless of load and extra energy simply get wasted?(in resistor or other ways)
I have no knowledge of electric motors but common sense dictates that it is probable that if only 2hp is used then only slightly more than 2hp of input is consumed. Maybe I have got this wrong and will soon be told so if that is the case.
Someone said "alternating current motors generally will draw only sufficient current to match the load. An AC motor under no load draws very little current
regardless of its rated horsepower. It will increase its draw as the load increases. There is such a thing as over-motoring a piece of equipment with an AC motor. I'm not sure how it works, but there is an inefficiency
in say, attaching a ten HP motor where a 1 hp would be adequate. Direct current motors will draw a fixed amount of current regardless of the load."
Just want to get things straight once and for all.
Thanks.
