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 !

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 !
