A low cost sub-/urban city car : 3,75 €/Kg car weight price
Compared :
Xpeng P7 18,75 €/Kg weight price
Tesla S      44      €/Kg weight price

In cities with average velocities ≤ 40 Km-h and in future autonomous driving the price for such vehicles will be in common in the ≤ 10 €/Kg range and ≤ 1000 Kg/car weight  !

Here are wheel hubs. Take out the stub axle and bolt on the wheel (and a fair bit more):
http://www.cnqsmotor.com/en/article_read/QS%20MOTOR%20High%20power%2012kw%2024kw%2070H%20V3%20e%20car%20hub%20motor%20for%20100KPH%20Speed/275.html
It is limited to 62 mph. A gearing issue, I suppose.

Good morning,
12 KW average and 24 KW peak power to 57 Kg : 1 KW peak /2,4  Kg ratio

Too fat and assuming heat problems by this case !
The Tesla cars have  1 KWp /0,2 Kg by 18000 rpm max ,compared newest Siemens 1 KWp/0,1 Kg  !

When high rpm becomes common then I prefer the Ferreira electric motor , 2 x 5 KW peak power output and
2x 25 Watt per 50 km range consume !
The 1 Wh/Km ( only drive,without extra appliances like AC et cetera ) eLoremo will become reality !

But 18000 rpm peak means high friction , I calculate 3750 hours bearing life without surface treatment !


When we look for the Garwood electric car numbers this means 2 x 1,5 KW average and 2x 3 KW peak for

                                              52 mph peak velocity = ≥ 80 Km-h  ! Sufficient for City traffic !

Pssst

Lanca....is this real or had problems ...?

hope things are OK by you...
This hyper link just goes to a newspaper advert it's not easy to get out of unless I delete that window.
It's an information fishing site.

ramset," summertime and the wind blows easy ,....." or Thanks God it is Friday  :)
I hope for you that your life is also well !
I can confirm AlienGrey his site problems,about the information : I did notice it several months back !


Interestant the QS AC  motor delivered data :
48 V 24 Km-h,    60 V   30 Km-h and   72 V     36 Km-h average velocity what would mean - linear calculated -
                                                             220 V         110 Km-h

The Garwood Superelectric DC motor car equipped : 90 Volts

But next QS motor " product description"  data :
max. torque : 350 Nm for rated 12 KW ( in their list : 8 KW performance)! This is surprisingly low !

The Ferreira Cap-motor : up to 350 Volts ,
so for fast acceleration HV and/or HF is a need !

They are usually water cooled but I can't see any pipes. It needs to be with 90% effy; there will be 1.2 -  2.4kw coming out of it. It would melt. Very easy conversion from petrol to LX.

#10: or from petrol to 1 in-wheel or 2x in-wheel hybrid !

When the Arakelian 1 carbon part -7 hydrogen parts mix fuel means less 80% CO2,this 1 carbon part converting CO2 can become  captured to 80-90% by car filter ,

so for a 2000 Euros - e-drive + CO2 filter- investment the car owner gets an economical and ecological solution !
In urban zone up to 40/45 Km-h full electric,outer zone " low carbon emission" !

When there is an eco-ratio :
conventional ic combustion                                       30 CO2 units consume/emission

electric car   german all sources electricity               7,5 CO2 units consume/emission

electric car    solar/wind/water source electricity    1,25 CO2 units consume/emission



30 CO2 units conventional fuel to 3,75 CO2 units Arakelian Hydro-fuel less 80% CO2 exhaust capture by CO2 filter

means 0,75 CO2 units consume/emission : cleaner then pure electric cars !

Btw : I have to correct my #9 view- point : 350 Nm for 8 to 12 KW electric input is a good torque value,dependent rpm !
Here I compare with the Victor Arestov (ASiPP)  double winding modified  e- motors ( www.dujunov.com ),whose is converting and improving e-bikes and e-cars velocity and drive range  !

Another example :

Volkswagen Electric Dune Buggy : 201 hp ~ 309 Nm (228 lb-ft) electric motor



     We have to notice : 8 to 12 KW and 350 Nm QS motor 

                           versus 201 hp and 309 Nm  VW motor

How do the car maker calculate the hp/KW ratio and KW/Nm ratio ?

Even when I take the austinev.org combustion engine hp to electric motor KW ratio I would get
201 hp (VW EDB) x 12,5/136 ( austinev.org ratio )  = 18,5 KW for this 309 Nm

' 1 horse power ~ 745,7 Watt ~ 745,7 Nm/s  ' is something for the EE-"Kindergarten" ,not applicationable by different force kind variable devices !

The Tesla S P100D 967 Nm peak more with 45 KW to calculate than 450 KW ,Marketing/physics lever ratio !
And not 1 KW/0,2 Kg but 1 KW/2 Kg real world power -to-weight ratio !
45 KW ~ 450 Watth per 100 Kilometer ,very nearer the reality by 95% motor efficiency !

I don't know whether it is just me, Lanca, but I find your
posts very difficult to follow. This is a pity because I think
there is a large amount of valuable content.

EE-"Kindergarten" car power : 50 hp ~ 50 x 745,7 W(att) = 37,3 rated KW

Autonomous Sub-/Urban shuttle bus : 50 hp ~ 50 x 12,5/136 x 10/4,5 ~ 1 rated electric KW per hour

12,5/136 : www.austinev.org formula
10/45      : George Constantinescu hypersonic theory based flywheel transmission



                                     Lorentz force versus N. Tesla time

www.scienceabc.com Watts "horsepower" by steam power comparison marketing,
                            50 horsepower or   37,3 KW max. steam power ~ 1 KWh electricity

or nearly 2 Citroen x 2CV = 2x 24 hp max engines

From US inventor Gar(field)Wood his Superelectric base car with 2x 2 hp DC electric motors and peak 52 mph velocity to the japanese" Hino flatformer" with 2x in-wheel motors to the Reva NXG Electric City Car prototype technical numbers  to the "Canoon bus" ( where is the front and where is the back side  ;) )

www.solarjourneyusa.com traffic numbers

for the 99% US private households satisfying 100 miles range per day electric vehicle with 85 mph(Texas State highway 130) ,elsewhere 70-55 mph highway ( when free,rush hour average ≤ 24 mph) max. velocity !

In future,with "Autopilot/Tempomat",black-box-recorder, and smartphone-ID-GPS-triangulation each traffic participant gets 24/365 velocity observation : radar-society !

www.in-wheel.com peak/constant torque and peak/constant power

Remembering Roy Kessingers preview about industrial electric motor price development :
from 15 US$/hp down to 5 US$/hp: mass production price
The endconsumer pays in average with 500% margin for each unit  !
So the market price by 90 US$/hp will fall to 30 US$/hp  to finally open source  9 US$/hp( 80% margin)

The industrial parameter of production is not " hp" but for application and replication material " Kg" weight,3d digitizing,material spectrum scanning,cloning

the newest electric motors are - rpm dependent- in the 1 KW/0,1 Kg range
     Low weight = low financial investment need

9 US$/hp ~ 12 US/KW  divided  ? Kg material  worth ?
2008 I got for Kemmerich electro motors ( AC electro magnets ducted  ) price offer in the 12 €/Kg range !

                                  Sept. 2020 : 12 € ~ Kursgepflegte  14,2 US$ ( real,US credit-inflation reduced :   : 3 US$)   
     
                                                                                                   
From rare earth magnets to Metamaterial magnets to zero permanent magnets electric motors
From copper coils to copper-alu coils to alu coils to graphene film band to superconductive RT coils

Low cost materials in future !

www.evalbum.com  Lavenami
1,5 KW nominal electric motor , 40 Km/h peak velocity ~ sub-/urban speed limit and average

drive range           50        Kilometers by 12 V 70 Ah lead battery
                            200                                  12 V 280 Ah sodium or lithium battery ,same weight or volume

                            400 ?                               Valkenberg electric- 50% less consume-  drive ?
                          1200 ?                              Todorovic range extender

                          2400 ?                              Todorovic range extender and Akiro Hara generator

                          7200 ?                              Valkenberg + Todorovic + Hara with 500 Wh/Kg battery


                               41                               is the result from 15.000 Kilometers per year divided 365,25 days

                               71                                                               15.000                                                   210 workdays
                       
Or : 1,5 KW electric motor and Saburo battery-genset : over 10.000 kilometers drive range


Is this important,the investment worth ? Actually not in need !
