    kWeld - "Next level" DIY battery spot welder

    Hi! I'm looking for the ability to change weld power without using the knob. I have a small CNC-board on which the k-weld is mounted and I'm welding 21700 cells. The amount of power needed is different when welding the minus pole vs the plus pole and I want to automate the "change". Has anyone...

    Voltage spike when throttle is released.

    Hi! Got my me1616 running with a Sevcon gen4 size 4 72/80V. At first I had some trouble with the encoder and phase wires but after I figured that out i was able to spin the motor in fwd and rev-direction. I still have one issue and that’s a overvoltage fault that’s being triggered when I pull...

    how to program a sevcon gen4

    Just to clarify, some of the settings under motor configuration are “hw-specific” meaning that the apply to the hw resources available in the specific model on gen4? That do make sense and I should find a working gen4 size 4 80V dcf and start from there.

    how to program a sevcon gen4

    Hey! I think I got a taste of that mach 10 freewheeling today. I touched the throttle and the motor reved up, hitting some limit which caused the controller, gen4 size4, to issue a DSP overvoltage or Current control fault. I will check that my sine and cosine are not mixed up. Do you know if a...

    Electric Hydrofoil/E-Foil

    Hi all! I building and documenting based on Hiorth's DIY on instructables.com. It will be modified for water cooling and the "motor pipe" will be threaded not glued. You can see and follow the progress here https://www.facebook.com/Wildtech-1442876945788613/

    how to program a sevcon gen4

    That would be nice :) I saw that you referred to a base speed of 4400 rpm before id kicked in, at what system voltage was this, 72V? Was it for the me130x or for the 75-7 sr? Thanks Rikard

    Electric kart

    Hi Nuxland, Regarding the temperature difference of the motor and the controller, I've seen some strange behavior with the sevcon and kty. Did the motor temp change as soon as the motor started to spinn? I think it's a software bug. I saw it in sn0058.04

    how to program a sevcon gen4

    Hi Doc, Im riwe, in the article below from diyelectric car, I did a deep dive into Sevcon and field weakening during a dyno-test. "Id" is very much dependent on the Ke-value set in the controler. If the Ke is faulty the Id will kick in to early or to late. I had the wrong Ke when the graph...
