Awesome work Zechy :):), I will use your Camry version for my inverter in my E39 . Also many thanks for going over this data. Makes me think it was a worthwhile endeavor.

Thank you catphish, this is a very interesting subject

Years and years spent in close proximity of heavy machinnery will do that :). For me it was turbine propeller aircraft. The thing is you dont notice it until you put on really good protective earphones that cancel out any external sound. World is full of noise. Very interesting arber333, interestin...

oh here is a picture:

Very interesting Johu: Got tinnitus, too. Doctor just said "oh another software guy" [/quote] Well I thought I would measure the electric field with my Trifield meter in front of a node Ethernet phone connected to the WiFi box for a friend. I thought I would measure just a couple of volts ...

Ok well you have orders for 3 from me when you have the time,

Kind regards,

I have seen measurements of electric fields emanating from charge cables. Pretty bad, err very bad. When I last parked at a EV charging station my FM radio played up that's how bad the electrical interference was. I suspect these charging cables are not shielded. I have a trifield EM meter which I h...

I do have spare gears for the transaxle, but not the planetary gear for MG2. If you want them you can have them, but you would have to work out how to get them to yourself.

Kind regards,

Awesome Zechy, I will give you the HTM data too then. Its all a work in progress, please feel free to send questions. I still have the oscilloscope hooked up to the taxi on the front lawn, so can run special tests if that helps. Please note, the oscilloscope creates 32 sets of waveforms, which inclu...

PS: i love the LED you have added

Have you or are you going to create the Zeva current sensors?

I have bought the Zeva system for my car to install once I get to that stage, so I am very glad you have created these items

What year is your BMWer?

Panasonic AEV14012 Contactor i saw this heading in the Wiki: "This means they had to use one of theese on + line and another on - side. Together you get 240A rating for system with 800A for a burst of power." This sentence looks like a Panasonic contactor is required on the +ve side, and a...

Here are links to two PID loop simulators in Excel that may be of help to you Pete9008:

Do you need to add phase angle of current only during regeneration, i.e. stage 1 stage 2 type controller?

Are you making the calculations as fast and accurate as possible?

Yes makes complete sense, use what you have got (If it works don't fix it). Anyway, these 'old' things were made by tradesmen who were taught properly, perhaps the insulation used was better than what the books said to use... . So it is wonderful your Harrison L5 is humming along :) Yes well that is...

Perhaps this one Pee9008 will help with some of the understanding required here:


I did look for other MTPV papers, but most are not readily available, the reader has to ask for the paper.

Thank you SciroccoEV. Good photo of the rings :). One set of problems that can happen with induction motors is unwanted current flowing through the bearings causing havoc to the hard coating on the ball bearings, to solve that, if this problem can occur they insulate bearings at both ends of the mot...

Well that is very interesting arber333. I have seen a few papers on 5 phase motors for sometime. Not only is the inverter more complicated, but fault finding will be too. For a 3 phase motor that we are used to, faults can be catalogued into any combination of: positive, negative and zero sequence f...

Does that mean it has slip rings with carbon brushes for the rotor?

I like what you are doing heaps catphish. Thank you for showing me your code. I could not find quickly something on regeneration for IMs. Thank you for exploring IM current control, very interesting...

A few ideas: The curve for an induction motor flipping from motor to generator is almost the same, just rotated by 180: image.png You cannot change rotor speed, it is attached to car, you can change stator rotation rate >> change slip by changing 3 phase frequency going to Induction Motor...
