I finally got around to setting up a 12 fet controller. I looked at the documentation long enough to figure out the wiring, but never looked at programming. I wanted to see if I could make the controller run without reading anything. Historically FOC controllers have been fairly difficult to configure. I know this from personal experience. I wanted to see if these controllers would be easy or hard to configure. As it turns out, it was not hard at all. There's tons of features I really need to read about since I have no idea what they do. However within 20 minutes of power up, I had it running an inrunner.
ALL EV's, BMS, battery packs, contactors, motors and controllers I have are wired interchangeably. As a result I had to convert the Nucular 12 fet to work with what I do as a standard. It had 6mm bullets on the phase wires, but I use 5.5mm bullets everywhere. I use XT90's for charging ports and nothing else. It had to be replaced with 5.5mm bullets. I had to replace the better 6mm bullets for 5.5mm bullets or adapt down. It was easy enough to swap them out. I cut off the small connectors and replaced them with IP68 connectors. My motors, bench throttle and all my EV's use these exact connectors wired identically every time. Now I can plug this controller into any of my EV's, a little bit of programming and it is ready to go.
6mm bullets are better than 5.5mm, but fooey...everything I have uses 5.5mm.
This too got pulled off. 5.5mm bullets are a fair bit better than XT90's and you can connect up one power lead at a time with bullets. In my EV builds this is a charging port.
I'm not fond of non-water proof connectors at all and I don't like small unsupported wires. They tend to get broken. So a long time ago, all this sort of wiring went into IP68 connectors where the individual small wires are protected and can't get damaged.
This is the end result. 5.5mm bullets and IP68 connectors. THe 6 pin has halls and motor temp in it. The 8 pin has enable, throttle and 3 speeds.
Pinouts for the 2 IP68 connectors. Ignore the wire colors listed here. That's from another controller.
This is the small signal wires coming out of the Nucular controller. My connectors don't include brakes or variable regen. I never use the brake signal, but now that I have variable regen, I may use that via the connector on the back of the LCD. I never use cruise or reverse...don't care at all about them.
Plugged in and powered up for the first time.
