Testing Big AC Motor

[@ltr4300]

My grandpa was an electrician's mate in the Navy in WWII. He was stationed on Kwajalein in the Marshal Islands. He rewound everything from desk fans to battleship main gun motors. I think of him every time i see one of these videos. He would have loved it. He'd bring home unwanted motors and refurbish them in the basement, they'd run so quiet and smooth it was hard to tell they were running. Wish I'd learned while he was still around.

100 miles away a radio amateur is going 'where the hell is all this RF coming from'

[@MittyNuke1]

@Richard Vaughn The motor in the video appears to be a 3-phase induction motor meaning there are no brushes or capacitors. The biggest effect to the grid a motor like that will cause, is a reduction of power factor, which can be corrected by installing power factor correction capacitors on the grid or within the facility itself. The speed of the motor is dependent on the frequency used to drive the motor, not like a universal motor inside your vacuum cleaner/shop vac, which uses brushes and makes a bunch of sparks and runs at a much higher speed. I'm not an expert in radio so I don't know what kind of interference induction motors put out, but I can only assume it's much less than universal motors or anything that makes sparks like a universal motor.

[@santhony1978]

@@MittyNuke1 you are correct, sir. There are no brushes or capacitors in that beast. Kudos. 👍

[@kinangeagle133]

I dont get it

[@marc-andreservant201]

@@kinangeagle133 A brushed motor would produce sparks from the brushes and those sparks would emit radio interference. This is a 3-phase motor meaning it has a rotating magnetic field and doesn't need brushes. Therefore little RF is emitted. Plus the metal case acts like a Faraday cage.

I use to to rebuild/repair/refurbish and test these for a living. All the way from 120V 1/2hp up to 480V motors like this one. This one is about a quarter the size of the biggest one I've worked on. You have to have A LOT of respect for these, or they can kill or maim you in half a second.

[@seanjuth]

The one in this video looks to be about 100 Horsepower give or take. I couldn't imagine the size of wires they would need if something like this was for 240 volt or even 208. I've seen 50 HP motors wired for 208 volts with wires the size of half your hand for only phase phase

Reactive amps. The voltage and current are out of phase so the actual power being dissipated in the motor is only a few hundred watts, not the hundred+ kilowatts the volts x amps would indicate.

The most part off a running motor (not a starting one) is actual power. about 80 %.
