Electric Motor increase speed

[metalfire7]

Hi, I was wondering if it was possible to increase the speed of an already working electric motor by giving it more energy from a second power source? The increase of speed would only last 2-3 second then returning back to normal speed.

Increase speed by adding more energy from a 2nd power source? No.
Increase speed using Vfd ? probably.

I assume you are talking induction motor. Perhaps you should tell us what type motor, how large, what it drives, how much faster you want it to go, etc.

(2B)+(2B)' ?

DC motor, higher voltage fed in with a blocking diode to protect the normal source. Sure.

Before we waste a lot of time guessing, please explain in detail what you mean by "motor". There are literally hundreds of types of electric motors and it makes a difference as to how you might do that.

it's a sort of hypothetical question..unless you describe what you really mean, otherwise; guessing would never stop.
