    ME1616 motor with sevcon gen4 size 6 80V low power??

    I know this is an old thread but I wanted to chime in here and provide an answer to this low power issue. I have made two ATVs and a SXS with this motor now and I learned one important detail that was missed in this build and many others out there. In this example the motor was ran with a 86V...

    *SOLD* SEVCON Gen4 Size4 72/80V 350A SIN/COS-UVW-ACI controller PN 634A83203

    here are some resources if you have the DVT software and you are considering using Sevcon Gen4 units. The manual and other documents are out there, these documents are special documents that are written by other users and thus hard to find.

    Clearview Sevcon - Node DVT not detected

    Food for thought. I used an Arduino with a MCP2515 CAN bus module for my ATV conversion projects. Using a 2004 I2C 20x4 LCD display I displayed mph in big characters and other information in small characters. I added a button on the Arduino so I can switch to different page views. you an find...

    1st Post, 2nd Conversion: Coleman youth ATV

    More on why to go with more volts. Disregard if you already know this, I don't mean to insult anybody's knowledge. Think of it this way. Volts is HP (work/speed) which is directly proportional total weight the motor can push and the top work/speed it can reach. Meanwhile Amps current is torque...

    1st Post, 2nd Conversion: Coleman youth ATV

    I have converted several ATVs and a SXS. My first conversion was a kids ATV which I wrote an article about it and might help you in your build. I started with a 2kW motor and worked but was close to overheating, even after I geared it right. I ended up with a QS 138 3kW which had plenty of power...

    Sevcon Gen4 "Capactior Precharge Failure" Help!

    UPDATE: the controller died. :( I did buy it used and it seem to have a lot of hours on it so who knows what caused the issue. I hope my two other Sevcon controllers in my SXS and my other ATV lasts much longer than this one did. Anywho, now the controller says the contactor is welded but it...

    Sevcon Gen4 "Capactior Precharge Failure" Help!

    I am stumped and hoping someone out there has seen this issue before. I am building my third conversion using a Sevcon. I have a Gen4 Size4 80v 350A model but I bought it used. I didn't have a chance to use it to now. When I turn on the system the capacitor recharges but stops at a low voltage...

    Zero motor 75-7 markings, red sticker, DANGER?

    I have used Zero 75-7R motor that I have used in two of my builds. I was wondering what RPM range you are running. I found an old spec from Zero that says they can run 7500 but I have limited mine to 6000RPM. I would like to run higher RPMs in my side-by-side build but I don't want to kill the...

    Kids Polaris Sportsman 90 Quad ATV EV Electric Motor Swap Conversion Using a QS138 70H V3 Gearbox - VOTOL EM-150-2 - DKD

    ElectricGreene, I have thought just about the same thing, would it work for a 500lb machine. I would say yes but probably not support faster than 30-40mph. That being said I did build a second quad that is adult sized. I ended up with a ME1507 based design (later I swapped it for a Zero 75-7R)...

    Votol EM-100 & EM-150 controllers

    Atykotski, to switch the direction of the motor with the EM family controllers you swap the Hall sensor wires Yell-Blue and swap the motor phase wires Blue-Green. I have the EM-150-2 and the QS138 70H V3 I needed to switch the direction of my motor. I figure this out because I knew I had to...

    VOTOL EM-150-2SP software has zeros for RPM, Voltage and temp

    In my search for software versions I thought I should drop this direct link to download latest software versions from SiAECOSYS. I have seen elsewhere people looking for software but I didn't see this like to the supplier website. It would have saved me a lot of time if I found this sooner. I...

    VOTOL EM-150-2SP software has zeros for RPM, Voltage and temp

    Warning! I am newbie to the VOTOL EM software. I have it connected to my 2021 version of EM-150-2 and I see that my RPM and voltage display screen are zero along with no temperatures. However I can change settings without errors. What am I doing wrong? UPDATE: I see that it gets the parameters...

    Sevcon size4 ME1616 motor not rotating make only noice

    I got my bench test running. I had to swap the cos and sin wires which means I ended up reversed to the suggested wiring diagrams. I sent an email to the motor manufacturer asking them why mine is backwards in hopes to better understand my ME1507 motor. I also tried switching the phase wires...

    Sevcon size4 ME1616 motor not rotating make only noice

    Did you ever get your motor working? I am having the same issue with a ME1507. I am a newbie as well. I have the DVT software and I was given an example DCF file from Motenergy but it isn't working. I have no errors, contactor clicks, I am seeing throttle values in the software. Where do I start...
