Now do one up with carbon fiber windings and get it to make a 2 stroke noise and im in, brapppp. Would be nice to be a RAXIAL design with axial and radial flux, synchronous motors are a magetic rotary 2 stroke engine that can make insane power!
Looks good here, but want to see it in use at high volume production. Would love for Autoline to do an Afterhours show where they go over vaporware and true products from the past few years of expos and auto shows. Many products look good in the moment, but many never reach market. Maybe it could be a series of Afterhours so you can group together products in certain categories and bring in people with real experience and knowledge in that area. Maybe some of the Munro Live team would join in this. Keep up the great work Autoline.
The generator manufactures have been doing this for a long time. There are diodes between the inductor transformer and the main rotor windings. I expect the slice design to be more likely to be built since it uses the outer stater to power the inner rotor, but that's not a new design.
BMW and Renault developed patented this motor in 2022, The 5th-Generation Electric Drive System can be found in BMW’s I series vehicles as well as BMW’s plug-in hybrid vehicles.
This is genius. I mean really pure genius. Not only the contactless induction did anyone see how their winding is just ready for high voltage high current !? I wonder how much torque and horse power it can handle.
The No rate earth battery sounds good. And easily reverse engineered. That is good for everyone. If it is truly scalable. So many engine and battery announcements fade away over the follow up year.
Very cool you can demo a new motor and it fits on the little table in front of the speakers. One of the cool things you can do with a motor with no magnets is you can control the properties of the virtual magnets with software. That allows you to tune everything without actuators or moving parts like you have in some other motors. You can even retune the motor depending on speed and drag of vehicle in real time.
unfortunately everyone's not been paying attention, this is a further adaption of the 5th Gen Syncronous (sealed brush) AC motors BMW is already running in their new i4, i7, iX, and forthcoming i5. these too were expressly designed to forgo dependency on using rare earth magnets. so see contrary to the HYPE and PROPAGANDA Tesla is not able to "out engineer" the Germans, and these BMW's are available for purchase NOW... enjoy.
Exactly! I still don't understand how this is significantly different to one of the asynchronous motors with induction cages that have been in use for decades.
And adding a rotating inductor and diodes in the core to get DC to run the magnet has been done in generators. Although not mentioned there has to be diodes in that core area.
@@abstractora yes it has a rotating transformer like a larger version that a VCR head uses and then diodes to convert it to DC to drive the electromagnet in the core.
This is not new. Mahle came out with their inductive coupling 'magnetless' motor two years ago and claimed 96%+ peak efficiency. The ZF design seems to have only reduced the size of the inductive coupler used to excite the rotor. In the future, could some of these designs turn out to be more efficient overall than permanent magnet synchronous motors, by using the ability to fine tune the rotor's magnetic field for different operating conditions? ZF, Mahle and others need to score actual design wins for production car models. Go for high volume, low cost rather than trying to recover the R&D expense from a smaller volume of motors.
A little clarification is needed here as far as efficiency. Mark stated that his new motor doesn’t have the drag of brushes or moving contacts and that is true but it’s probably irrelevant in the EV space as I know of no EV that uses a DC (direct current) motor (which use brushes); all use AC motors which don’t use brushes. EV’s use DC charging because all batteries are DC but the DC is converted to AC to run the brushless AC motors.
re: "Mark stated that his new motor doesn’t have the drag of brushes or moving contacts and that is true but it’s probably irrelevant in the EV space as I know of no EV that uses a DC (direct current) motor (which use brushes); all use AC motors which don’t use brushes." he's referring to the new motors BMW Engineers designed (and have already deployed) in the i4, i5, i7, and iX. "PROST...!!!" (best Bavarian accent)
I am kinda with you on this. They address it at the end of the video (lower overall carbon footprint), but technically, it sounds like it's just a brushless motor that uses extra copper and less permanent magnets. So I guess the main play is supply chain stability?
Aloha, gotion is a Chinese country making batteries for many EV and other lithium battery users. Don’t you mean VW is contracting to buy Gotion batteries pre packaged in a Gotion designed and built platform? This is VW buying someone less batteries. It is a cost center, not a Remus center for them. VW is struggling to build batteries. FORD is now stuck further back in line, it seems, because VW can not 0achieve its battery manufacturing goals AGAIN. So VW is outsourcing battery packs and Ford is SOL Right?
re: "they've said it won't be using any rare earth metals." just to clarify, their original Induction motors found in the Model S (invented by their namesake Nikola Tesla) already didn't use rare earth metals. the center rotor is just a big ol' heavy BLUDGEON made of copper.
Has some advantages (no permanent magnets) but also added complexity. I don't think it is quite game changing. Tesla and others have come out with motors with ferrite magnets that do not contain rare earth elements. Probably cheaper than this motor...
