    Infineon programming cable question (non Prolific chipset)

    I suspect my problem is still to do with the halls. Do any of you guys have a trouble code led wired to the board? Did I understand correctly that there is one? I have one on connected to the LED/ diagnostic signal on the schematic (connects to R28). It turns on when I get 5V, but doesn't seem...

    Infineon programming cable question (non Prolific chipset)

    WOOT! I got it to programe :lol: So, what was it? Something dumb actually. I made a mistake in the cicuit and was not getting the 5V line. After fixing that, and adding a momentary switch in the 5V line it worked like a charm. So.. all down to my own thick-headed-ness. Unfortunately I am...

    SOLVED! Infineon Cutting out Question

    Thanks, I'm happy to hear that. What you were describing sounds exactly like what i am seeing. Funny little detail, it seems like when I set it up for 1 direction it works better (I have been able to slowly ramp up to full throttle a couple times), than the other direction (never been able to...

    Motor Controlers fro RC Motor's

    I think maybe we need to take a couple steps back, just to for clarity. 1st point: The RC motors you see on this site are called BLDC (BrushLess DC) motors. In this type of motor, the windings/electromagnets that you are powering do not move, rather the permanent magnets move. The motor...

    Adding sensors to a Astro 3210 motor

    You mean something like this? http://scolton.blogspot.com/2010/01/3ph-duo-wrap-up-part-1-field-oriented.html A very interesting read, he is going a couple steps further too though. Very cool results Burtie, very cool! -Matt

    SOLVED! Infineon Cutting out Question

    gwhy! I was wondering if this was the same as you were experiencing. I temporarily fitted the halls inside the motor, in the gaps where the wire is wound, spaced equally (120deg mechanical). It should provide corect timing I thought? I seem to remember something about diffferent hall placement...

    SOLVED! Infineon Cutting out Question

    Hi, I have a Turnigy 63-74 that I added hall sensors to and I have hooked it up to a 6-fet infineon controller. The issue that I am having is that I seem to have found a phase/hall wiring combo that works. I can roll the throttle on gently and the motor starts to run with a low no-load current...

    Infineon programming cable question (non Prolific chipset)

    Geoff, unfortunately I didn't take any pictures of my controller PCB. The pic I posted was one that someone had already posted. If I have the controller apart again, I will try to remember to snap some pics. -Matt

    Infineon programming cable question (non Prolific chipset)

    I actually didn't have anything connected to it (except the programming cable)). That is a good point though, next time I will check to make sure I am getting full 5V.

    Infineon programming cable question (non Prolific chipset)

    Yes I did the hyperterminal test. I have also used this same cable for communicating with other uC's so I know it works. I saw in another post something about making sure that some of the unused serial signals were grounded. Do you guys know anything about that? I only saw it mentioned in one...

    Infineon programming cable question (non Prolific chipset)

    Hi, I have just bought a 48V EB206 6-fet Infineon controller, and I am trying to program it. I have a USB-TTL serial cable, and I soldered in a connector like this: however I have not had luck programming. I am using a USB-TTL converter that uses FTDI chipset. The software runs fine (doesn't...

    Motobecane Cady with an RC drive

    Bubba, my understanding has been that the integral term is important if you need to reach a precise point (like a servo position), it helps to amplify small errors so that you eventually converge to the desired state. If The motor consumes 2.1A instead of 2A, that is close enough for me :D...

    Motobecane Cady with an RC drive

    Now that is good idea! I don't see any reason I couldn't duplicate that, thanks! :D If all goes well, my ultimate plan would be to convert something like a vintage vespa using an 80-100 at least, along with with a capable controller and enough battery to give me usable range/power. I saw a...

    Motobecane Cady with an RC drive

    gwhy!, I thought this may have been the same motor you are using. Good to hear that it can stand up to some abuse. I would like to add a bearing on the output shaft, but the stock shaft is too short. Did you replace your shaft? Also, the bike does not have a variator, so I will be sticking with...

    Motobecane Cady with an RC drive

    The bigger Motobecanes can be a little heavy and hard to pedal. My girlfriend has a 50V mobylette, and it is a B1tch to pedal if the motor quits, and weighs maybe 80-100lbs. The Cady that I am working on though is a real lightweight. 40-50lbs, and pedals allot like a bike, not much of drag. The...

    Motobecane Cady with an RC drive

    I remember that build, I really liked it. Was the turnigy really under powered, or was it that you couldn't get full power/torque right from a start? -Matt

    Motobecane Cady with an RC drive

    I will likely add more lipo once the setup is working. I'll be honest, I'm more interested in seeing how far I can push these components, and not trying to compete for most powerful ebike.... yet! 8) The stock motor is only 1-2hp, so it won't take much to improve on that. If I can re-program the...

    Motobecane Cady with an RC drive

    I have spent enough time on this forum reading about other people projects, it is finally time for me to stop skulking and give something back. So, here is my first project: It has a 49cc motor, single gear ratio (no variator). Here are the bits I'm going to use for the first phase of the...

    My ES torque contest DIY motor build thread.

    Hi all, I just want to start by saying that I think this an awesome thread! I have keenly been watching it since it started. From what i am reading, it sounds like the consensus is that copper foil lamination allow for good fill, but will cause increased losses due to induced eddy currents at...

    Grinhill's Medium-power RC-Motor Hardtail build

    Ah.. that is the one company that I had heard of using the method... and they are located just down the road from me(Montreal) in Ontario! Cool Video, I am surprised more people are not talking about this method. -Matt

    Grinhill's Medium-power RC-Motor Hardtail build

    This has likely been outlined somewhere else, but: A sensorless BLDC driver depends on BEMF to detect which phases of the motor to energize. The BEMF is a result of the magnet moving in relation to the motor coils, causing a changing magnetic field. This means that the motor must be turning...

    Grinhill's Medium-power RC-Motor Hardtail build

    Has anyone considered replacing the firmware on a cheap esc?? There are guys using these brushless controllers in quadrocopters, and they need i2c interfaces, and fast response, so some have bought cheap chinese esc's since it is simpler/cheaper than making your own, and replaced the firmware...

    Best battery?

    just to state the obvious 60A at 72V is only 4.3kW, well within the limits of a Ping pack. Of course if 60A is your expected average consumption, your peak requirements will be much higher than 8kW. 4kW isn't much of a peak power for a motorcycle, so I suspect it is your average expected power...

    analog bldc zero cross detector

    Hi, This is an interesting post. I work for a company that makes electronic valve actuators. We have been looking at going from stepper motors to bldc to gain better speed/torque/efficiency. I have done a fair amount of online research into sensor less control. You may already know this, but...
