On the monoblock vs segmented magnets, I would recommend using magnaview film to see if the magnet is segmented inside of the external plating. The other thing to check is the electrical conductivity of the magnet to see if they added anything to the magnet that would reduce the electrical conductivity before sintering it. Both methods could be used to reduce eddy currents.

@satoshimanabe2493 Месяц назад

As I understand it, rare-earth magnets use sintered material (not poured into a mold in a liquid state). So perhaps a nonconductive binder (instead of sintering) is possible, in which case there would be no eddy losses on any axis. (The counterpoint is that such a structure would not benefit from being plated...so this may not be the case.)

@patrickmorse7549 Месяц назад

@@satoshimanabe2493 the plating is typically alternating layers of nickel an copper and while I agree that eddy currents may be generated in the plating it is very difficult to build up eddy currents into very thin conductive sheets. I have spent a lot of time using induction power to evaporate metal in a vacuum chamber and bulk blocks are much easier to get thermal power into than thin conductive sheets. This is also why laminations are used. Lastly the plating would still be essential as Neodynimum based magnets are highly succeptialbe to moisture based corrosion.

@@patrickmorse7549 Thanks for the explanation about plating, very helpful. What I meant by non-sintered, seems it's actually called bonded magnets (I'm sure you're familiar).

@DBlackRihno Месяц назад

Great video, thank you so much for putting this for free! Some thoughts on the non segmented magnets: First of all, yes there are eddy current losses in the magnets but they are quite small compared to iron and copper losses. Still they can be problematic since they are the heat source in a temperature sensitive part. One problem with the segmentation is that you will lose some torque because of having less magnet material in the rotor. This will make the motor a bit less efficient. I think that this loss of efficiency could be more than the additional eddy current losses. However, these eddy current losses are mainly due to the current harmonics caused by the PWM. This means that you can drastically influence the magnet losses by the PWM. Maybe Tesla optimized their PWM in order to reduce the magnet losses for not having to segment the magnets.

that spring loaded pin to catch and stop outer race from spinning is so smart of an idea.. and Sandy's response "so anyways..." lol

@neilfromclearwaterfl81 Месяц назад

It's an interesting solution but... The tiny pin may prevent a small problem from quickly becoming a bigger one however at the power and torque levels involved once that bearing gets grabby its going to spin unless the operator notices the change in sound when it starts to fail and has it serviced expeditiously. Time will tell whether having that pin tear loose causes more damage than it prevents. Hopefully the MTBF of those bearings exceeds the half to one million mile operational life expectation of the vehicle. I can see that spring loaded pin failing and causing damage similar to other implementations using spring located pins that we've had for some time in pneumatic and hydraulic tools. If the damage isn't too catastrophic sometimes I've been able to just clean up the seating area and drill a new hole for the locating pin and spring while other times its weld and machine a new surface or replace that part of the housing depending on the cost of the part and the value of the unit or perhaps the cost of the downtime. Like Sandy said:. so anyways... ;> Best!

I think the magnets issue is so that tesla intentionally makes the motor hotter so that it can use that heat to keep the battery warm in colder weather. It is really the only motor that is running most of the time and especially on the highway. So, there is a lot of heat loss in colder climates. Basically, they don't have to add a heater, but then they can modulate the cooling for hotter climates, or even shift the work to the induction motors. I am just guessing, but I'm usually right.

Induction and PM synchronous motors sharing stator design is good, but not new - Tesla has done that since their first PM motor, in the Model 3. Like the Model 3, the axial lengths are different, to suit different flux density and power requirements. Long before Tesla, Remy (now BorgWarner) offered their HVH series (which is also bar-wound with hairpins) with a choice of induction or PM rotors using exactly the same stator. It's good to see Tesla continuing this practice, and finally catching up to use bar winding.

Tesla has greater integration in their engineering teams than anyone else, and I will bet there are many conversations that go, "Hey! I gained X% more something!" to which another engineer says, "Did you consider XYZ?" ...."Oh shit! Back to the drawing board" From which they end up with a third option that solves both problems. This is why I don't think many manufacturers are going to catch up all that quickly. Would love to see how the latest Mach-E compares to the first version.

In terms of the magnets, I'd be surprised if Tesla weren't on top of the gains segmented magnets can offer and I'd suspect they were not that significant, especially since the magnetic flux at part load operation is pretty modest compared with full torque so the losses would be not huge for most of the time.

The segmented magnets make great sense if the truck is only operating in hot climates. But Tesla uses motor inefficiencies to generate heat to put into the heat pump that keeps the battery and cab warm. It may well be that when they run the calculations, the extra heat is required more often and the solid batteries allow this to be generated faster and at less electrical cost. Rapid warm up and keeping the battery warm is very important. Not to mention creature comfort.

So does the dual motor configuration have two of the fronts that are in the cyber beast? Do we know that yet?

@ReinReads Месяц назад

The rear motor on the dual motor model is a single configuration of the induction rear motors used here.

@markkelliher5216 Месяц назад

So to be clear on the front differential- it's not limited slip, it's an electronic locker- giving a true Detroit locker type of performance?

@imconsequetau5275 Месяц назад

This locker allows both electric motors to send combined torque to the wheel that grips. Only really needed if a single motor has insufficient torque, which is a weakness in the PM reluctance rotor design.

@mikeselectricstuff Месяц назад

Could it be that the magnet is segmented internally, inside the outer plating, or made of a less electrically conductive material to reduce eddy curent losses?

@celeron55 Месяц назад

How much eddy current loss there is in a magnet though? Doesn't the stator aim to keep the magnetic field quite constant relative to the magnets, and a constant field definitely doesn't produce eddy currents!

@davidanalyst671 Месяц назад

you don't put an outer metal plating on a series of magnets. Thats magnets 101 man. Any metal solidly connected to the magnets would distort the mag field. You could segment the magnets, wrap in saran wrap, and then dip in liquid steel, like they dip snickers bars in chocolate, but that would increase the distance from magnetic material to the lectric coils it reacts with.... so you wouldn't do that.

@mikeselectricstuff , Wow, you would be a great addition to the Monroe reverse engineering team. I can hear your whispering voice now discussing the finer details as the components are carefully disassembled. I have been waiting for the day you disassemble an MRI superconducting magnet on your channel.

@kazedcat Месяц назад

I assume they did something to the metallurgy of the permanent magnet. That would be a low hanging fruit. Tweak the silicon content or add some exotic element and bam eddy current is reduced significantly.

@matthewmosher7676 Месяц назад

14:50 Munro, are we sure there are significant eddy currents in a Permanent Magnet Synchronous Motor? The whole point of the word Synchronous is that the magnetic pole from the stator is rotating in phase with the rotor’s permanent magnetic field poles. If there is significant pole slipping (relative movement between stator and rotor) then I think there is a problem in design or control systems. Relative movement between the field and conductor is required for an eddy current.

@kazedcat Месяц назад

We know heating is a problem that is why they opened up the end plate to get oil in. So there must be significant heating losses happening in the rotor near the magnets. Otherwise it would be much easier to fabricate the rotor all sealed up.

@imconsequetau5275 Месяц назад

The magnetic field is still passed from pole to pole in the stator. Even when three or so poles overlap per winding, there is some field fluctuation passing through the rotor. So it's like amplitude modulation.

Heat can reduce or destroy magnetism. So cooling them may also increase magnet life/power.

Amazing what EV’s have done with just first generations. Just think a few more generations. Battery tech is also rapidly changing

I think Tesla is more like the 4th generation major design. BMW appears to be on the 2nd generation. Most others are on the first generation although able to get a few ideas from Tesla if they are smart. Cool to see everyone making design improvements.

@@MatthewDeveloper - It depends where you are and the charging network. Tesla superchargers are 100% renewable power from a combination of onsite resources and annual renewable matching. Those EV owners with home solar may also be 100% renewable today.

“Piston car can’t go 3/4 million miles,,,,,” 30 years ago Lexus causally makes the LS400 which can go over million miles 🤯

@tesla_tap Месяц назад

Doesn't it require lots of maintenance to do that? Timing chains, value adjustments and replacements, spark plugs, rings, and more will need to be replaced along the way, multiple times. If you keep replacing enough parts it could go millions of miles, although nothing will be original.

@richardwolf6269 Месяц назад

Electric motors are awesome but what is the life expectancy of the battery which is the most expensive component? The million mile Tesla S had several motors and batteries replaced. Parts for many ICE vehicles are cheap and readily available. Teslas not so much so!

@tesla_tap Месяц назад

@@richardwolf6269 - Engines, Cataltyic converters, and timing chains are are not cheap either. Engines after 100K miles have reduced MPG too as the rings and valves wear and it starts burning oil. Battery packs generally don't really die, they just have less range over time, perhaps 80% of the original after 250K miles. Motors and packs keep getting better, but agree that for the very early Model S, getting a million miles will take a few packs and motors. The EV's "fuel" and maintenance savings are far more than those expense even on the early models.

@sparksmcgee6641 14 дней назад

@@richardwolf6269 cost waaay less than the ICE that get there. Keep in mind that many that get there as ICE it takes 25 or 30 years because it was was parked in a garage and drove at 45 mph. There are no ICE taxis with over 500k on them in a fleet. Bet Uber would find out they have a 100 model S with that on them if they asked the fleet.

@Gamegenio 20 дней назад

Is the solid magnet for the motor the reason there is a pulsing vibration at some speeds? This is reminiscent of older automatic transmission when you are traveling at a speed that is kind of between two gears.
