Re: UK & EUROPE EV PARTS SUPPLIERS

Ack, I bought a few things from Kartmasters.
The shop is not organised very well, and some parts are a bit expensive. But that is because the cater to kart builders.
I was also offered a good shipping deal without asking for it. Was very happy.

Re: BESC - beefed up VESC motor controller for high power ebikes

Thank you. Very good explanation of the trade-offs. Especially at the motor side.
And don't worry I didn't pay so much, more like ~2k. https://evshop.eu/en/controllers/63-con ... cx144.html

Re: BESC - beefed up VESC motor controller for high power ebikes

Yes I know, I bought one recently. [emoji16] HyPer-Drive X144, nice part. VESC wasn't quite there yet for me. However, the price scales more with current than with voltage. I think a lot of he high cost people see, are somewhat self inflicted and avoidable with higher voltage systems. Either crimina...

Re: BESC - beefed up VESC motor controller for high power ebikes

The benefit of winding it like that is lower phase current per driver only?
Naively I would think that a six pole motor can be hooked up to a three phase driver by hooking up the phases in parallel. Is that so?
Sorry for those questions, I just wondered if I understood that right?

Re: Running a 230V 50hz Stove from UK

Come on, the frequency difference is meaningless in practice. You say stove, is that just a heater or does it have some 'smarts'? If it's just a heater, it will just run with half the power in the us. You might want to consider that if that's enough for you. As those transformers are hidiously expen...

Good plan I think. Even somewhat overkill.
Maybe you can borrow a spot welder. If you are in EU I can give you my kWeld for a while. Or sell you my suniko 787A+ for very little (my hiuse fuses are too small)

Re: VESC ADC input help

You got GND, signal and +5V on your ADC port. Should be obvious.
Works with poti and hall style throttles.
Just calibrate the endpoints right via the input wizard.

Please ask specific questions.

Re: AliExpress battery pack unboxing

That nickel strip is a bit unfortunate. But you'd be putting in a lot of heat trying to solder on a copper busbar. Perhaps just add a second tap off on the other end of the strip. Silicone cooling pad is a great idea. It's always best to suck the heat from the terminals. The smart BMS has one great ...

Re: Tesla M3 teardown information video - Hallbach Array Motor

There might be a different safety certification process involved for electricians working on the car. But probably not. 600v DC kill you just as much as 900v DC. Bosh iirc offers powertrains that can be serviced my non HV certified garages. But they are very meager power. Won't be long and all garag...

Re: Tesla M3 teardown information video - Hallbach Array Motor

Unrelated question. What relationship does higher voltage (800 vs 400) have to higher charge rates? Mostly a question of wire thickness in the case of DC fast charge. The charge cable and plugs can only support a certain amount of amps. To get more power through, you need to raise the voltage. Copp...

Random moment of frustration on my side. :D Nevermind me, just had a moment.
In fact, I could tell from the style the question was asked that no prior research was done about the matter at all. I only engaged to see where it leads for amusement sake.

Re: (PLEASE HELP) Electric Motorcycle, Controller Questions

The controller manual is ominously silent about this.
No comment if the field wiring part is perhaps optional.

I would perhaps drop Curtis a quick email.
