And the wood could provide energy for ALL the vehicles on the planet? (Back to the original question : Mrgreen: )

Just ask him ... But for the moment, there is no shortage of rare earths and permanent magnets.

Impossible to answer precisely if one does not know the number of vehicles concerned .... But a priori, no, especially considering the low yield of the envisaged solutions ...

Wood, it is certain, will not be able to cover all the energy needs of the planet, especially since the available resource is low: it is already the first "renewable" energy used (especially in France), only the difficulty of counting its consumption (it largely escapes the commercial circuits) prevents this primacy from being well known.

Tesla Motors has abandoned the induction motor because permanent magnet motors are smaller, lighter, more efficient. https://forums.tesla.com/forum/forums/m ... technology

The huge induction motor that equips the Tesla S:

The engine of the Tesla S is a product of the Taiwanese Fukuta Motor Co. Ltd., a specialist in induction motors. Link: https://www.fukuta-motor.com.tw/en/products.html

Can this technology replace the current one?

chatelot16 and Gaston will give us the answer.

But what is "current" technology? The induction motor?

The induction motor is completely marginal. It must be a lot less than 0,1% of the world fleet, including Tesla who just dropped it ...

Yes since the initial question is: what energy (to date) to replace the world fleet (and not a few thousand vehicles here and there) of all types of vehicles ...

I asked if this induction motor could represent this energy there: not according to what you say ...

So question still pending ..... : Mrgreen:

the choice of the type of electric motor is a detail

even the good old DC motor is not that bad

what is the difference between a DC motor and a synchronous motor? in one case the current is cut by the coal, in the other case it is cut by electronics ... but the yield can be the same in the 2 case

true difference: the old DC motor operates at low frequency with medium-quality magnetic sheet as used long ago ... the modern motor has the greatest number of poles, the finest magnetic sheet suitable for higher frequency ... we would make DC motor with the same progress we would have the same benefits

similarly for the comparison between synchronous or asynchronous motor: it is the quality of the magnetic circuit that makes the performance ... synchronous or asynchronous does not change much ... it changes when comparing an old asynchronous with a recent synchronous. .. but there will definitely be a newer asynchronous that will do as well

for me asynchronous has the advantage of simplicity
