    BESC - beefed up VESC motor controller for high power ebikes

    Hey Galp, Any chance I can buy like an hour of your time to help me trouble shoot my besc clone? I've made the PCB mostly modeled after your V1 board with some changes to suit myself. But I just wanted to ask a few questions on what you did with the firmware. For eg on inverting the current...

    Yep..Another VESC Based Ebike Controller 150V 200AMP

    Hey All, Finished with the drive part of my design today. DAMN, it took a long time to finish this and it was a total $%# to route. I've opted to just go with a smaller 6 fet power stage right now TO-220 Package . I'll upgrade the drive board design once I validate the design and put some...

    Yep..Another VESC Based Ebike Controller 150V 200AMP

    Got my PCB's from JLC and got my components on there. Just a few to solder on for the ADC inputs but so far everything on the board is checking out ok. Got the board bootloaded and VESC firmware flashed. Actively using VESC tool and all I/Os I can currently test seem ok. Including the Servo...

    VESC based +200A powerstage with 200V MOSFETs (videos of it in action)

    Zombiess, You are so epic good man. Thanks for the really in depth explanation. I can see already my controller is a bit of a joke in comparison to yours. But I'm coming off the old lyen controller days still have that on my ebike running irfb4115's at 30s 50a. Been doing that for YEARS with...

    VESC based +200A powerstage with 200V MOSFETs (videos of it in action)

    Damn, this is nice stuff.. I was working on a separated control and power stage controller but now I feel I missed out on picking your brain for a lot of stuff. Your control board looks nice. Is it open source? I would like to see the schematics if possible. Looks like you have optos on all...

    Yep..Another VESC Based Ebike Controller 150V 200AMP

    Hey all, Been a hot heavy min since I've been on here. 2020 has been a complete nightmare for me. I lost my daughter River to a heart defect at 2.5mo old. She was a real fighter having had open heart surgery at day 5. She was born with TGA a disease where AORTA and PULMONARY arteries are...

    infineon controller schematics

    Hey guys, I tried to do a search to find some schematics, I remember being available for the generic ebike controllers we all use/mod. I remember there was one posted someplace but a search didn't get me to where I was hoping. Anyone mind sharing a link or PDF of the schematics that are...

    Xie Chang Controller SMPS Design

    Anyone? Was really hoping someone else was interested in the design of this simple 2 transistor switch mode power supply. Mo

    Xie Chang Controller SMPS Design

    Hey Yall, Anyone ever find a schematic for the Xie Chang controller SMPS? This switch mode power supply is so killer I would love to know how to make it. It's so simple and useful. Has a crazy wide input range of 22v - 150v. My knowledge of transistors and making a circuit like this fails...

    Rewinding 9C Motor

    Thanks guys! I actually watched that video before I started.. It helped me a lot. I've wound a lot of RC motors in the past before but found it quite challenging to wind this motor up. I started using the technique from the women in the videos and it sped things up a whole lot! I staggered...

    New 6 FET Water Cooled using 200v 230Amp FETS!! :D

    Hummmmmmmm You guys bring up a few pretty good points I hadn't even considered.... On the other controller that I had made successfully (6 Fet) I only replaced all the caps with 200-400v versions of everything and one transistor with a higher voltage unit.. Made tails for my two largest caps...

    New 6 FET Water Cooled using 200v 230Amp FETS!! :D

    This is a pic of my work table.. Things are a realllllllllll mess right now .. But you can see my old controller sitting on the table .. This picture shows the up standing FETS I took the sinks off the controller and used them for something else. So this controller is currently homeless.

    New 6 FET Water Cooled using 200v 230Amp FETS!! :D

    No it's actually a 6fet controller. 3 fets up 3 fets to the side.. You sort of can't see it in the picture. In the Picture your looking at the FETS out to the side. On the previous post I had made regarding that controller there is a pic from the top side of the Controller board which makes it...

    New 6 FET Water Cooled using 200v 230Amp FETS!! :D

    Lol Tell me about it! I made this Controller last year and it really worked great.. My only main issue was it was a bitch to mount the FETS. I made the mistake of not getting them with holes in them. This controller should behave the same but should allow a much smaller sink source and be a...

    New 6 FET Water Cooled using 200v 230Amp FETS!! :D

    Okay okay so before you all jump on me .. No the controller wont do 230AMPS lol.. but it sure will do a lot for a 6 Fet. I plan to do it very similarly to my old 6FET but this time I have TO-264s so mounting should be easier and I will use two aluminum slabs that will have two channels for inlet...

    New Ebike Digital Throttle Curve Managment

    Hey Guys, So I finished my Ebike Motor Control Throttle Management system but now I've been sitting on it for a couple of weeks.. I've lost my motivation doing a hundred other things. Tonight when I get home from work I'll start by putting up some pictures. I wanted to actually make you guys a...

    Rewinding 9C Motor

    Hey Guys! So I'm going to be rewinding a 9C motor. It's one of the older ones not sure exactly which, but it has 63 teeth on the Stator and 56 Teeth on the Rotor. It's wound AaABbBCcCAaA.... with 6 Strands 6 Turns. I want to do a silly slow wind so I'm going with 14T. Now my question is...

    Taming the twist grip throttle

    Yeah it's actually working surprisingly well. I thought there was someone on here working on it a year or so ago but I didn't see it develop. I recently learned a decent bit of hardware and software at work which made me feel comfortable enough to try it. I apply 2nd and 3rd order polynomial...

    Taming the twist grip throttle

    Morning Guys, I've been working on a solution to this problem this last week,. Winter time I develop R&D for ebikes and summer time I Ride! :D I have made a little harness that attaches between the throttle and controller that will allow you to apply different curves to the throttle response...

    Part for HobbyKing 6 Cell Balance connector.

    Thanks guys GMuseless. Very Useful Post. Thanks.. I think i'll be using the surface mount versions of these. I'm making a 30 cell battery monitor with contactor shut off for my bike.. I'll post about it when I'm done. Mo

    Part for HobbyKing 6 Cell Balance connector.

    Hi guys! I was wondering if anyone had the DIgikey or Mouser part numbers for the Balance leads on Hobby King batteries. I think it's called JST or somthing? Regardless I need the Male and Female part numbers for 6 Cell Packs. I'm brew'n up something pretty cool, Thanks for the help guys Mo

    Motor Selection

    Yeah Wow! really great break down. Thanks guys.. Has anyone ever heard of HS4065 motors? Also if I could do a group buy of 5403's even tho I don't have much reputation here... I could prepay and show the goods in pictures if I knew there were interest. WOULD YOU GUYS BE INTERESTED? I think...

    Motor Selection

    Hey guys, Quick question. I've always used 9c Motors. I bought one of those clearance units from Justin way back in the day for $120 and am still using it constantly while giving it 120v at about 25 amps. Now on to my question. I want to move on to crystalite so I can put more power into...
