Thanks One of the most important issues in the field of refrigeration is to be able to detect the status of a compressor And thus also determine what the rules are for the terminals in a conventional system, thanks for the contribution, today's lesson is very good

@will7its 2 года назад

Very good video. Got right into it without all the fluff. This is what I was looking for. Thank You

I'm still relatively new in the trade but I have applied myself to learn everything I can every single day. My field is residential, but one day I hope to transition into the commercial side and maybe the refrigeration side😌🤓🤔🤔

@HVACS are there any draw back from using a Single to three-phase converter Nx where there is no 3 phase available so long as it can match the kW?

@skullduggeryafoot Год назад

this is good info, but i really wish you'd at least leave the autogenerated captions on, my dude. some of us have auditory processing issues out here.

The bottom line is to know what your Source Voltage is. The quickest way to find that out is to look at the Disconnect Switch that should be installed nearby. If not a (DS), then there should be a Circuit Breaker in a Panel. A single pole and two pole breakers are considered Single Phase. And of course, a three pole breaker would obviously be 3-Phase. In terms of Single Phase vs. Three Phase.......3-Phase offers 173% more power. Kind of like the difference between a 4 Cylinder Engine and a V8 Engine.

Thanks for the concise information. I assume those are AC motors. How does a DC motor differ? Is it just that the electromagnetic fields are generated on the armature instead of the stator? I'm over my head. Trying to utilize a MFR-J55WZ0BP-0114 to upgrade my drill press for low RPM high torque drilling of metal. I can't find much info that motor. It doesn't seem to have brushes, indicates 3 phases with an insulation rating of F. Yes, I did rip it out of a treadmill. :) Which came with some type of Emerson driver.

@Hhh-xm8zi 3 года назад

thank you ... can you talk about 3 phase in dc motors

@cbirch7302 2 года назад

Strictly speaking, DC cannot have different phases in the first place. DC is just on or off. The entire concept of a "phase" only truly applies to AC power. It is the definition of AC vs DC power, really. The confusion comes from how people talk about variable speed motors. Even manufacturer literature. Carrier's modulating heat pump, for example. On one page it says the compressor gets "300v 3 phase power", with no mention of AC or DC, leaving you to assume AC because only AC truly has phases. But 2 pages later it says the compressor receives a 300v*DC* input. So is the compressor AC or DC? Well, both. It takes a DC signal thats mimicking an AC signal using something called "Pulse Width Modulation". It basically delivers short bursts of power (1/1500th of a second each) in a way that results in an oscillating voltage that approximately resembles an AC sine wave. So even though a "3 phase DC" motor does *technically* take a DC input, it's a DC input that is made to approximate an AC input. So for most purposes, it can be treated exactly like a 3 phase *AC* motor. Essentially, 3 phase DC motors *do not exist.* Because DC doesn't have phases in the first place. All "3 phase DC" motors only work because the DC signal is made to look like an AC signal. That's the only reason the term "DC phases" makes sense in the first place; if the DC is essentially turned into AC through PWM.

I bought a couple of exhaust fans online that I wanted to use in my house, when they arrived they turned out to have 3-phase motors. How can I hook these to my 110V power in the house? Do I need a single to 3-phase converter? Thank you!

@Alvin-in3zt 11 месяцев назад

Yes

@RobiBue 2 года назад

I like the way when he says "ninety degrees" and the text corrects to "*120°"... tbh, since the video is so often cut, a correction take wouldn't have been too much instead of patching the correct phase shift value text in there...

@will7its 2 года назад

Yeah I was thinking would'nt that be 4 phase???

@daveeckmann9568 3 года назад

I always try to think of 3 phase power and motor as a 3 cylinder engine...firing at every 120 deg of rotation. (if that helps any) 3 phase power has 73% more power than its 1 phase counterpart. The one that always throws me off is a 120 volt motor with neutral and a 240 volt motor with 2 hot legs are both considered single phase?? Shouldn't the 240 volt motor be 2 phase?? ...and the 120 volt w/ neutral be single phase??..LOL just sayin...GR8 job on all of your vids that I have watched so far...you have great information for sure..A+

@deang5622 Год назад

And that is because the producer did a very poor job at explaining it and why it is so fundamentally important. Probably doesn't understand it properly himself.
