    Induction motor sevcon gen4 issue

    Should be a near direct swap to semi clone an 80v gen 4. You need the offroad polaris dld to start. Why would you consider this? A Ranger doesn't really need hotrodding. 35mph is easy enough at 48v, and oem controller can handle 60v.

    Solid nickel better, easier? Not sure I have nickel. Any other material, cu etc.? Also trying cca button. Weld al to al and solder to cu side. Some success but not ready to do batteries yet.

    Best Method for Battery Build??? 16s4p Telsa 2170 Cells

    Practicing spot welding tig on a beer can. This 100ms and 60 amps. Nickel plated strip. Small 18awg aluminum wire is tough to do. Also able to weld copper plated aluminum for soldering.

    Best Method for Battery Build??? 16s4p Telsa 2170 Cells

    Tnx, good info. Worth any amount of work for me. Saving a 12 brick battery by repairing one or two cells is a win. Is there anything to coat tops with to prevent oxidation before welding? I tried split plated strip at full power with Sunoco welder. Not enough power? It melts the strip. More...

    Best Method for Battery Build??? 16s4p Telsa 2170 Cells

    I'm not building a pack. Just need to repair a few fused wires on the pack. The K-weld site says no, just as every other post I can find. I have not yet bought a new welder. Price is trivial if it works. Do you have cells to try? Glad to send some out for test welds. (usa)

    Best Method for Battery Build??? 16s4p Telsa 2170 Cells

    Wire fusing amps is about 5. I often blow them when building reconfigured packs. If you can teach me how to spot weld anything to positive terminal, it will save me a lot of time and money. I need a way to repair my mistakes. I've tried aluminum, copper, and nickel ribbon. Enough power to...

    Best Method for Battery Build??? 16s4p Telsa 2170 Cells

    I too am looking for answers. I have been splitting tesla3 modules into useable lengths. So far I have not been able to repair fused links. Today I tried various methods and materials using an 800w 40khz welder. Zero success so far. Ordered a smaller horn/tip today, but I have little confidence...

    New smart bms connectors

    What is the new 2.0mm pitch connector used on new version bms? GoGo won't tell me. Grrrr. He did say that it was not jst-ph. I got a sample TE 2.0 with latch that does not fit. jst-phd?

    Alight sin/cos encoder of motenergy motor with SEVCON

    Is the second encoder offset set to Zero for Motenergy motors? No offset number is supplied with motor. http://odynesupport.com/odyne/odscontent/service/SERV_Set_Sevcon_Inverter_Motor_Resolver_Parameter_091917.pdf

    how to program a sevcon gen4

    P34 is current limited for use with a 2 wire throttle. I have not done it, but clamp it with a 5v zener and measure current. A few hundred ma is safe for a common 5w 5v.

    Pmac tuning

    Possible solution. Put in a known working dcf and I have the same run away. I did not yet change the sw (dld) to known working one. That seems to point at a dld that controls this function. Good news I think. Smile Taking a break from the heat now.

    Pmac tuning

    Not bad, just not normal. It feels like it's more than coasting. Raining here so I have not been able to test anything. Maybe it's different for pmac. What Secon calls neutral braking in induction motor control, is regen when lifting throttle. Down hill I can often see over 50a charging...

    Pmac tuning

    No fix yet, but it's a neutral braking issue. Set to 10% which explains the torque level. Torque is supplied in the same rotation as drive when breaking. Timing problem? Or is there a setting for brake torque positive or negative values? I need neutral braking, vehicle coasts forever without it.

    Pmac tuning

    I'm tuning a pmac which I have running smoothly. ME-3031 S6 Gen4 sevcon. Running in torque mode. Motor is stable when powered on at zero speed. With slight throttle F or R accelerates with about 10% torque. Runs away until braked to a stop. Pushing car in neutral F or R has same effect. Not...
