6 Phase Power is a REAL GAME CHANGER!

3 phase is not only a very efficient way to transfer a lot of power, it is the MOST efficient way to transfer maximum power with minimal wiring and other necessary parts. From single phase power you get to 3 phase with just 1 extra wire, no neutral now required. So by adding 50% more wires (1 extra) you get 300% more power. Additionally, if you have a 3 phase Wye supply, you could theoretically run 3 individual single phase loads with only 4 wires (each line plus a single neutral return) and have it run with no current needing to flow over the neutral except for any imbalance between the loads. It is a ridiculously efficient power transfer mechanism.

So why don't EV's use straight DC? Seems like that would be the ideal design

Most 3 phase motors are induction motors and are not synchronous.

Wow! They developed a Tire Pressure Monitoring System! ... That'll never catch on.

It is a simple matter to convert three phase to six phase (or 9 or 12) via transformers. This was once common for use with rotary synchronous converters as their capacity and efficiency are considerably improved.

However, for transmission, three phase is the most economical.

Shifting your assets from oil (ie gasoline and diesel) to coal and natural gas (ie the overwhelming majority of electric power) accomplishes virtually no “decarbonization” whatsoever. “Decarbonization” should be initially focused on electricity generation, if the goal really was “decarbonization” in the first place.

YT is censoring comments here now too.

Seems like we are now and forever bound to expedient convenience with our extremely outdated electrical grid systems. Just upping the frequency would save a few million tons of copper in wiring.

Multiphase power has an additional advantage. It causes less inductive reactance than lower phase power because there is less change of flux. This is an advantage in reducing losses in transmission lines and underground distribution.

Why not 3 phase 400hz like we use in the military?

We can definitely force 6 phase into existence nationwide. We just need to get investors involved, then lobby Congress to pass laws forcing its acceptance. Awe yeah. Living the dream

12 phase by next year

At what temperature does a lithium battery reach
Thermal runaway, ?

6-Phase is actually just 3-phase and it's inverted counterpart, you can generate it with 3-phase transformer with center-tapped secondaries (which is sometimes done for driving lots of 120/240, from a 3-phase source, with a balanced draw.

Nice, I wonder what voltage that battery is.

Nice try. A 3 phase motor does not have only 3 field coils.

nobody's saying anything about motors only being on 3 tires??

Talk about being out of touch with reality, as well as with your fan base.
Making battery-powered race cars is pointless, because the audience for stock car racing is not “woke” enough to go for this. If it doesn’t feature the roar of a V8 engine, it’s worthless to your audience and they won’t support you and you will go out of business. So you might as well save the effort and money by just shutting it all down. The DEI people will certainly not save you!

Video cards use 20 phase.

96 phase power ... dirty dc!

F no

Many arguments that you pose for 6 phases are just overthrown by adding mores poles within tne motors. this is standard in the industrial stuffs since the 3 phase motor was invented.
Asynchronus to reduce the speed of the motor with the same supply or eaven integreted 2 sets of windings within a motor to have a 2 speed.
Synchronus to have smoother and higher torque as you have to drive it with a VDF anyway.
The real issue is than with 3 phases 6 or eaven 12 poles motors, you need to switch the frequency extremely faster, giving a shitty power curve. The argument is that ev cars have to go trough such a RPM range with a high torque that it's preferable to double the number of phases and keep a low frequency than to integrate a gearbox in such a competitive environement. For porduction cars, extreme weight reduction and such optimisation is not necessary, so they are for many automatic 2 or 3 speed gearbox.

why even go there - de-carbonising a racetrack is a nonsense, and unfortunately 35 merely pays homage to the UN/WEF Agenda 2035 absurdity. And it is unnecessary as CO2 is not the devil nor is methane (CO yes!), go back to school… Water vapour is the largest component (fortunately) of purported global warming.

Awesome channel. Great content and presenter. Well done.

Why don't we use 6-phase? Because seriously difference between 3 and 4 phase isn't worth it... much less 3 to 6.... where there is more than double the cost, a LOT more complexity in protection systems, and you get AT BEST ~60% more conversion... its just not worth it for anything but extreme circumstances. Besides, most motors don't have just 3 poles for a 3 phase motor, and run at freqencies that make this pretty much a moot point for anything but again... extreme circumstances.

NASCAR will 100% be dead 😵 if they do this

Electric cars will result in the rebirth of car racing (which was shut down all over USA due to noise concerns of the gas engines).

The only time I have ever seen 6 phase was an F-18 IDG . I hated those things.

Why use AC instead of DC??

So when is Milwaukee gonna integrate that into their drills?

EVERY issue with EVs comes down to the battery capacity, cost, lifespan, materials, or performance.

I can't remember the forum I was in now, but Elon and the team looked at 6 phase, as you can have with higher voltage, potentially allowing for lower current per phase, potentially improved fault tolerance (one phase failing doesn’t cripple the entire motor), reduced torque ripple, and potentially smoother operation. However, this comes with added complexity in power electronics design, cost of more power semiconductor devices, a larger inverter, and more complicated control software. The Model S Plaid and M3 performance give supercars a run for their money and they are sedans that cost a fraction as much - so I'm wagering Tesla knows something these guys don't. :)

Just wait till this man finds out about 12 phase power lol

Three phase power can be easily converted to 6 phase with a transformer.

There are two winding methods for 3 phase, delta and Y. Delta connects coils between the phases. Y connects coils to a center point called Neutral (the same neutral in 120/240 power). If I make a transformer with both delta and Y winding of the same voltage, on the output, there is a 60 degree phase shift between the delta and Y. We used that to create a 12 phase rectifier for charging batteries.

Six phase isn't used on the grid because it requires more high voltage wires on the power poles. In fact with 3 phase, I can combine sections of delta and Y windings to create even more phases.

You dont need to change the entire system to 6 phase. You could just add a delay or phase shifter on the three phases inside the devices that need 6.

Isn't that top drawing 2 phases, 180 degrees opposed?

If you look carefully at the 6 phase coil diagram, that is what 3ph real coils look like. So a 6ph motor is a 3ph motor with double coils running on 3ph.

6 Phase isn't worth it in motors cause there is this thing called momentum, it averages the power delivery out. More so when geared, which would be the case here.
Electric motors have "turns", this just tells you how many coils you have for each phase, evenly distributed in the motor. This reduces the mechanical angle between phases in the motor, making 3 phase and 6 phase near identical for power distribution
If you lose a phase in either case you'll still be able to drive if already at speed. 3 phase you'll basically limp home, 6 phase you probably won't have the power to be competitive.

There's nothing special about the number of phases, it's all about the application. Single, two, three, four, five, and six all have their uses.

Electronic conversion of DC to AC is the real game-changer here. To get 6-phase power, you no longer need a 6-phase generator. You can make it from DC, and you can make DC from single-phase AC.

Electrical engineer here... 6 phase is better than 3 phase but only by a tiny fraction. The gains are offset by the need for additional cables etc and are never worth it. The only people that really benefit from a 6 phase system are the people who sell you the HV transmission wire. They sell twice as much cable and are very keen to implement your idea asap.

ABB-
Already
Broken or
Bypassed

What isn’t electrified on the NASCAR facilities besides the racecars? Are they possibly talking about switching the pace cars and tow trucks to EV?

I thought EV drive motors were dc, not ac. For precise speed control. If I am correct, then the motors are 6 pole dc motors, not 6 phase. More info please.

Your drawing of six phase is actually what a 3 phase motor looks like. The windings have poles in pairs.

Also reducing the degrees between poles will smooth the torque response but lower the actual torque. Although this can be manipulated by certain motor drives, which I’m certain ABB is using in this car so it’s probably a moot point.

Why not 42 phase?

6 phase has higher torque output, very similar power delivery for the amount of copper used (so also for the weight). Both have very even continuous power application.
the major difference beyond the torque for similar sized motors, is that 6 phase is much more complex and expensive. (like 2-3 times for the same power)

Seriously, this isn't a crazy game changer the way 3 phase was. Arguably marginally better in a couple niche applications where there's a need for high torque and limited size/weight. Similar to the reasons some applications use 400Hz, but it's not what we use for our power grid.

The world cannot sustain 100% EV. We will need to open numerous nuclear facilities to keep up with the large electrical charging demand. And we are 40 min years out of implementing that demand. wind, solar, and hydro is all a scam. Yes it creates clean energy but to maintain those systems, NOT SUSTAINABLE. Live Long the Internal Combustion Engine.

Huge problem with EVs is that we're using more of our grid which is majority coal and natural gas still. If we transitioned to alot more nuclear energy plants then EVs would be more practical.
