Re: Re-wind of a turnigy 80/100 (Now-tutorial w/Video)

Yep controller is the limiting factor at the moment. I'm using VESCs which are purpose built for electric skateboards. They are very good but I need to up the voltage to get more power out of them.

Re: Re-wind of a turnigy 80/100 (Now-tutorial w/Video)

Apologies in advance as this is not strictly on topic.. I’m hoping some subscribers to this topic may have information on a SK3 6374 rewind? I’m currently using two 6374 149kv motors as hub motors on my E-skate. It goes well, just over 50 km/h on 6S lipo. As you can imagine, the current required on ...

Re: Doctorbass 2WD ADAPTTO / NYX / MXUS 32kW 105 pounds

Just read back through the discussion about the new 14kW Max-e. If it is in fact just the gate driver boards that have been changed I wonder if Adaptto would sell us those separately to allow us to upgrade our old version Adaptto..

Trade me had some cheap tyres back when I was looking. There were a bunch new CST 90/90R19 for $10 each. maybe not what you're looking for but they make a decent road tyre

Sounds bloody awesome mate you should be able to do some damage with that setup! Regarding heat dissipation in the batteries, im sure others on ES have packed them hexagonally without issues and on higher discharge rates. If you know the internal resistance of the battery you can calculate the power...

Re: Planning/build thread, DH frame, Mini-E, QS 205 w/ LG HG

Nice 2.214 kWh thats heaps of battery capacity!

How was the shipping cost for all those batteries? I've been finding that shipping LiPo to NZ is getting more and more expensive.

Definitely going to keep an eye on this build

Re: Electric Surf Board

Thats going to be a lot of battery.. Unfortunately the power requirement for such watercraft is quite large and so you do need a big battery to get decent run times. I think this ~10kW system is a nice amount of power. But lets look at the battery required to get half hour run times @ 190A on 14S 19...

Hey Benjamin, Would like to say you are the master of motor control, these VESCs are amazing! Cant wait to see how they go with FOC. Will the older revision PCBs (V2.8) be able to run FOC? Also just wondering if there would be any issues if I were to swap the FETs for the AUIRFS8409-7P ? I have a 14...

Re: QSMOTOR 0.5kW-12kW BLDC Hub Motor Index

A few people are doing this as an attempt to improve heat transfer from the stator to the side covers. Black surfaces will absorb heat through radiation a higher rate. I have no idea how much difference it makes but will probably try it myself at some stage

For some reason I thought you were putting the faster 3T mxus on the front wheel and 4T on the rear.. Did you decide to swap them around?

It would be cool to see a direct comparison between the clyte 5403 and the mxus. Although I assume the speed constant are too different to get a fair comparison?

Posted this earlier in an other thread. What do you think about implementing this, Vedder? My idea was to simply make a current controlled boost converter using one or two FETs (depending on if it is synchronous or not), an inductor and a MCU to run the control loop. Then the whole charger logic ca...
