I have this old 1/3 HP AC Motor attached to a furnace fan that I want to control the speed of. I want to slow it down. I have done a lot of research, but I am not an electronics engineer so I get lost by the terminology and I'm not sure what I have and what I need.
It looks to be a single speed motor from what I can tell, with no built in way to make it run slower. Is this motor brushed or brushless?
Can I control with one of these options?

I see VFD come up often as a recommendation, but my searches turn up expensive options!
