electromagnetic bearings actively controlled 10000 times per second for survival may be complicated and expensiveZynerji wrote: ↑Thu Jun 08, 2023 5:02 pmNot impressed. Not at all. Fluid bearings, investment casting water jackets, Tesla cars open patents for best asynchronous motors of all time.Bill wrote: ↑Thu Jun 08, 2023 4:56 pmno is not a dumb motor ,it can spin over 200000 rpm and work at a excess temperature of over 1000 degree celcius,it can recover energy ,deploy energy and work to overcome turbo lag .in a nutshell it work in extreme conditions which need high level knowledge in material science and big budget.a jet engine is just a big shaft with lots fans ,a rocket engine is just a hallow tube that burn rocket fuel but we all know is not that simply.
It's about the assembly, optimization of windings, and tuning the "harmonics" of the M->G->M control strategy.
The 2014 units while not as powerful as today's units would still be beneficial from a spec unit perspective, and probably way less expensive.
and transistors generating precision-timed precision-shaped excitation pulses for 2000 revs/sec are at the limit
best asynchronous - my eye !
Tesla is about 70% efficient generator>battery>motor
F1 is about 90%
that's what's wrong with Z's pulsed combustion F1 thing
F1 has a very efficient electromagnetic 'gearbox' (called a CU) and a very efficient mechanical gearbox
