Motor speed controller

OK, so I don't see a question there... What exactly is it that you want to know?

If the product uses a typical universal brush-type motor with no built- in electronics, you can probably just use a lamp dimmer. If it's rated to run, for example, on 100-240V with no switching, it's just about guaranteed to have some electronics inside and will likely react poorly (not run right; never run again; ...) to being operated on pulsed or lower voltage input. Perhaps that helps answer the question you didn't ask but were wondering about.

Cheers, Tom

Yes, thank you.
