If anyone was curious, the high current when the variac was being used is exactly why you do not undervolt AC motors - single or three phase. They will over-current until they burn out. If you want to control speed of an AC motor, you use a VFD, and a three phase motor ideally. However in this instance it's probably alright as it's a demonstration, but I still would never recommend doing it. Just figured I'd point that out, as some people don't know this.

I made a waste oil centrifuge using the smaller one in this video. Manley 10 , 110-120v 3.3A 60hz and I need to slow it down. Can I use one of those Amazon plug in blower speed controllers? Or do I need to wire in a cap or something. I already set the thing up and hoping not to have to take it apart.

@@David_Mash Check if it's a trailing or leading edge dimmer. If it is, you may be okay so long as it can handle at least 500w of power. If it just changes the voltage directly then no because you'll run into over-current issues.

@@liorb3494 I couldn't tell you exactly. Though if you're dealing with smaller single phase motors, with the appropriate LEADING-edge dimmer you can control the speed of them better than if you were to undervolt them. There are various installations where leading edge dimmers are used to precisely control fan speed. You must not use trailing edge dimmers though as they can damage themselves and/or the motors.

Those are for small bounce houses, the big ones resemble more of a furnace blower and are usually rated around 15 amps also I think their rated for 1/2hp or so conservatively.

Good video! I have a yellow FJ-25 that looks just like the one you tore apart, that I got at Goodwill for $12.99. It’s a 325 W model, therefore the motor isn’t quite as powerful as yours. It works fine (to a fault). Unless a friend of mine wants it, I’m returning mine to Goodwill. I originally got it to rapidly air dry things. Like I said, it works! But whatever I’m air drying needs to be nailed down. It knocked a vacuum cleaner dirt cup off the table, but miraculously it did not crack. Nevertheless, I don’t need a wind tunnel machine for my air drying needs if it means blowing stuff around.

so our bouncy house was operating fine with the stock blower for a couple years. We took it to a local park, and set it up. Life was good for about an hour, then we noticed the house couldnt maintain air anymore. So it was 1 of 2 things. #1... there might be a hole. I looked EVERYWHERE and could not locate any hole in the fabric. #2... something wrong with the blower. I took it apart, and it was completely clean of debris. Any reason there could be something up with the blower itself? Any way that I could check the blower? What would I look for?

Well these blowers spin pretty fast like 3000 to 3450 RPM's if you run it without anything on the blower the air coming out of it should be very strong (about the same as a leaf blower). Did you look for holes on the bottom of the bouncy house?
