Response of a motor rotor to just 1/60th of a second of current

[Dale]

So if the rotor is quite heavy. Then the 1/60 sec pulse won't cause any movement.

How can you possibly conclude that from what I or anyone else in this thread has said? What physical law are you invoking to make that claim in contradiction to what you have been told?

You are just making stuff up.

I don't understand. Is it not you just wrote:

"Sure. There is more energy delivered in 1 s than in 1/60 s. But do you think that the energy delivered in 1/60 s is zero? If it is not zero then there must be some force and some acceleration. ".

Meaning if it is not zero it must be some force and some acceleration smaller than 1 sec.. so if the 1/60 sec pulse is smaller in value, then the rotor needs to be lighter too. What is the problem with this analysis? I'm not making up things. Just trying to understand.

1/59th sec is smaller than 1 sec too.

OK, you need to stop with this thread then and learn Newton’s laws first. The rotor does not need to be lighter, the change in speed is simply smaller, but still non-zero.

This thread is pointless until you learn Newton’s laws. I am closing it for now. Once you have learned Newton’s laws then you can start over asking about motors. Right now you are simply not prepared with the necessary background to understand the answers that you have already been given.

Thread closed
