don't want to miss the opportunity to have the first GaN e-bike :D :D :D :D :D :D :D something like the VESC-X bu with with this Mosfet http://eu.mouser.com/ds/2/692/GS66516B%20DS%20Rev%20170321-1107590.pdf , Low current , high voltage , very efficient. Also it will work good on my solar car

OK , let's do it ! send PM to me

as far I know the driver part is the same of regular mosfet , also the load sharing is the same of the mosfet For sure I know that 3 Formula E team already use this kind of mosfet but form online store looks like now is possible also for "normal" people to use it I'm not an expert electronic...

what do you think about this type of chip ? in the high voltage , low current can be easier to use this mosfet instead of one IGBT http://eu.mouser.com/ds/2/692/GS66516B%20DS%20Rev%20170321-1107590.pdf

I have a Emrax 228 and emsiso H300 , up to today the biggest problem is the lack of the precharge by the controller , but is more or less working some error are not so clear and also the fact that the tuning paramenters are divided in application is sometime confusing

i'm currently using this motor in a project , I will keep you updated how it goes

the most significant is the starting temperature of the motor , in winter you get much more time than in summer or form an hot motor. Second depends on airflow on the fin , i did some try with oilcooling the ZF motor but if air cooled performance are enough for you the best is just to stay on...

why do you think GaN and SiC need to mature more ? some OEM part supplier for cars have already GaN Level2 charger for Electric cars ready for the market https://chargedevs.com/newswire/level-2-charger-with-gan-semiconductors-achieves-record-efficiency/

I'm looking into the spec of some GaN transistor and they look much better than normal MOSFET , for example this http://www.gansystems.com/datasheets/20150904/GS61008T%20DS%20Rev%20150904.pdf transistor is a 100 V 7,4 mOhm and is only 3mm x 6 mm big and is rated for a peak current of 90Ampere ...

Hello, i'm building a batterypack based on LG 18650HE2 2500 mAh 20A IMR. 36s 30p , I have 30 nickel strip in parallel connecting each "s" at the side of the pack I would like to use aluminium busbar to collect the current from the 30 nickel strip ( a bigger aluminium busbar is lighter than an...

interesting document , also it points out that 2 layer windings have higher loss for added interference between 2 phases , 1 layer windings have higher loss for longer end turn but maybe with the better copperfilling of 1 layer and also with this reduced interference 1 layer windings can still...

you can use a wire throttle from a motorcicle and a dual output potentiometer for the 2 throtte , dual potentiometer are very common in audio when you have to regulate the volume for left and right channel. is very cheap and works perfectly

lamination works because they are insuladet , if you put a screw shorting the lamination together there wil be a huge drop in efficiency and the motor will have a localized overheating. Also drilling a hole will interfere with the magnetic flux and some other parts of the lamination will...

ok , got it . It will turn , current will be banced but it will be unbalanced the mechanical force vector , a lot of noise and the bearing will suffer a lot and with this configuration there is nothing you can do ( skewing , magnet shape or other solution) BTW reading the thesis I never...

Hello , somenone have experience in outrunner with 9 slot 10 magnetpole configuration? It will run smooth or il will be unbalanced? From the windings looks unbalanced but with a rethinking the vector from the 3 phases should balance.
