    Axiom: a 100kW+ motor controller

    Uhm. Duty cycle is not actually duty cycle. Its a calculation of something it jumps to negative duty at times. So I have not worried a lot about it but I do look at it as when its a cleaner signal it seems to run smoother.

    Fuji 1MBI800U4B-120 IGBTs new for sale DISCOUNT! Updated September 9 2023

    Bump. I Dropped the price. I need to get some cash flow in the business to pay some debts. Long story but going though a divorce and trying not to loose everything. Not asking for sympathy just looking to find a way to thread the needle and have a fair outcome. If anyone thinks I have...

    Axiom: a 100kW+ motor controller

    Thanks Luke. I only left them laying in the controllers while they are not in USE. I have not decided what we want to do as a long term solution. Where I live relative humidity is common @99%. My shop stays ~ 40-50% But the Controllers will soon be outside under the hood and rear in the CRX...

    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    Hi Everyone, I have 6 of these IGBTs in stock the 1MBI800U4B-120 parts new in a box I can sell at my cost. ($295 ea USD) I have multiple controller projects on the go right now and they use different parts so I don't know if I will use these. I also have a few boards I can put another kit...

    Thread for new battery breakthrough PR releases

    Its also worth pointing out once the 4680 is fully sorted out it will produce less heat. So the need for cooling will not be as important. I would think if you can use a 4680 over a 2170 when it produces less heat per KW of power given to the drive train. This will be a non issue. The...

    Axiom: a 100kW+ motor controller

    What you need is a picture with a tape measure. LOL you show a picture of the Power-stage with the digital (control stage) on the side. But what you don't see is the digital stage is actually closer to the power stage then ours is. Axiom is simply a larger controller and there its not the same...

    2014 Chevy Spark 100Kw Permanent Magnet Motor

    Yes you don't want lower than OEM voltage if anything a little higher will help. Many of these motors use a decent amount of field-weakening as it is and the point where the FW starts is where you torque starts to slowly taper off. If you use a lower voltage that rpm is lower as well meaning...

    Axiom: a 100kW+ motor controller

    I don't think you understand the level of work HH or the rest of our team has done and does on a daily basis. All connectors are going to stay to one side. There is many reasons for this but the biggest is the ease of install. One can argue that having things coming out on all sides of the...

    Axiom: a 100kW+ motor controller

    Did you see any of my dyno videos? I have almost 2 years of dyno testing with this and I have pushed it VERY hard never had any failures. I did do a LOT of things that would have made my other early controller fail and Axiom just faulted and shut down like intended saving everything! Anyways...

    Axiom: a 100kW+ motor controller

    These are not VENDOR POSTS at all! All files have been shared including an early PCB file. But many changes have been made and we are likely to make a few more. -Code 100% all open source and we have been the biggest contributors to the code other than Benjamin himself. All parts of this...

    Axiom: a 100kW+ motor controller

    We did not share the PCB design you are correct. The biggest reason is we don't want the risk of someone doing something wrong then blaming us for a fire or a death. Everything else is there. All of the rest will come. Remember we are also dealing with chip shortages. The main control board...

    Axiom: a 100kW+ motor controller

    Yes That is the most recent set of files we have shared. There is some minor changes we can share soon. But I want to make sure I have tested everything first.

    Axiom: a 100kW+ motor controller

    A lot has changed since that post. The most recent files shared are on Hackaday. RJ45 is long gone and has been for years. We have had a lot of challenges getting this done most are not related to Axiom at all but other contracts (something paying our bills) and kids, life etc. Everything...

    Axiom: a 100kW+ motor controller

    Whoa whoa whoa... All in time. I don't think you know who you are talking to or what all the members of our team are able to accomplish and do for a living on a daily basis! This is an open source motor controller. You can go to hackaday and download it all then open up a PCB editor and...

    Axiom: a 100kW+ motor controller

    Been making a lot of progress on this behind the scenes working with a machine shop to make it easy to machine the enclosure and printed a test to see how it will bolt together.
