This is NOT exactly new technology. The same arrangements are used in power plants which uses slip ring for exciter circuit. Instead of slip ring, Mahle uses magnetic induction to transfer power from static coil to movable coil in the rotor, then convert to DC into exciter coils. It works as motor by applying rotating AC field in the stator coil. It works as generator when external motive force are applied to the rotor (regen braking), produced AC power in the stator coil.
@@alexlo7708 It is a variation of synchronous motor invented by Tesla. In the common classical Induction synchronous motor, rotating 3 phase current in the stator produce field which induces current in end-shorted squirrel cage, which produced opposing field in the rotor, which then produce motive force.
"It works as motor by applying rotating AC field in the stator coil" -- does that mean it is still a BLDC motor, but its permanent magnets are replaced by electromagnets that are energised by the DC currents converted from the AC voltage induced from outside (contactless commutator of some kind)?
Good morning, could you explain to me how to produce an alternating current from direct current? I had a number of theories Original em português Bom dia poderia me explicar como fazem para produzir a corrente alternada a partir da corrente continua ? Tive uma série de teorias
Da kann man nur sagen... hut ab. Dieser transferiert die Energie wie ein Transformator (ueber das metal zwischen den Spulen), welche perfekte wiederverwertung der Technologie. Die Frage ist nur, ob man so einen Motor auch "flach" machen kann, so dass er in artikulierte Roboter eingebaut werden kann, speziell solche die einen sehr grossen Rotor-Shaft haben.

So it is a simple synchronous motor that has been in use for hundreds years.

have you found any patents related to this exact product?

I believe it uses an inverter like a lot of EVs & Hybrids do.

Mich juckt nur ob ich das bald in meinen Haushaltsgeräten hab.
Very smart to use a transformer to send power wirelessly! :D
Can this same technology be of use in the design of car alternators?
Theoretically, yes.
Hi I am suraj Kumar
What are it's regenerative braking capabilities?
I think power some coil in rotator and then you have electricity in stator? 🤔
Doesn't it work like an alternator?
@@Eduardo_Espinoza Yep, but the electricity gets transferred to the rotor coil via magnetic induction instead of using brushes.
gotcha, thanks:)@@IrelandLover
@@Eduardo_Espinoza :)
1:54 title here told
Coil induced mag field
Can Mahle supply wheel motor for tractor application.
Gibt es dazu schon unabhängige Tests? Klingt sehr interessant!
Can this motor be used as a generator
I think so, since it's like an alternator :)
Yes, but you'd need an activation current just like in an alternator.
It’s same as standard Sync motor function !!!!
I love ev.
👍👍👍
man engineering droput here, i want to build my first motor, to power my UAP
🎉
Can i have this motor in India, Maharashtra
Is this motor sold commercially already, or is this still in development?
Still under development.
Sadly, the production is very complicated -> expensive.
