    My new Colossus Water Cooled motor

    On the original motor, I was running the bit for about a year. My biggest issue was the battery pack, the way I had connected the headways in the middle caused no end of trouble. I did burn out the original prototype motor on one phase (connect a temp sensor). I acquired two more of the...

    New Kelly pseudo FOC controller series

    That is a major reason for selecting the isolated controller. Finding a small switch rated for 96v is difficult, 12v switches won't last and they may not turn off after quite a short number of uses. Also having 96v wiring exposed to the extremities of the bike and and user operated controls is...

    Axiom: a 100kW+ motor controller

    marcos, that is an awesome teaser and a solid result.

    Suzuki RF400E, now with Enertrac MHM602

    Looking at the "bulb" how does the cutoff change when you switch to high beam, do you get more light spread and also forward and up?

    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    You absolutely need more traction. Is the light end really light, I remember you strapping it down?

    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    Some nice ideas there for some of the stuff. Yep the speed had an error that has been calculated. I might have a look at moving the calculation of speed outside the disabled interrupt as it is only the reset of the volatile variable that is "required" to be in there. If the odometer is required...

    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    Note there is filtering on the speed now... so play with the #define FILTER_SPEED 0.4 line to improve the responsiveness, the closer the number gets to 1.0 the faster the response. Tony

    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    Ok updated the code to take in the good feedback from the people here.... Changes include: More parameters to the readThermistor function to allow any model of thermistor to be read Constant changes to support the above Variable name changes from temp and temp2 to tempMotor and tempController...

    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    Thanks it was a quick tidy up. Will remove all the extra code soon.

    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    Hey Arlo I have tidied your code again. The reason for functions is so you don't have to copy and paste code, so I have modified the temperature function. I have also used Lebowski's filter code on the temperature (rather than average) and the speedo. Note again I have moved the calculations...

    Hi power inverter for Nissan leaf motor. Dyno's 302.3hp p15

    Nice bit of code. so it allows a maximum rate of change compared to the previous filtered value. I assume you set filtered x to zero to start. I might add that to the code Arlo is using

    New Kelly pseudo FOC controller series

    Correct I was lax with my language. You will need a serial sniffer to figure it out. I think there is a thread that someone else created on this.

    Thanks for all your work mate.

    New Kelly pseudo FOC controller series

    Sorry no... the my world has been a bit crazy of the last 6 months. I have learnt that over the serial you need to "ask" for the data (Fany from Kelly told me that), he also recommended that I use the Can-Bus output as that continuously streams the data.

    New Kelly pseudo FOC controller series

    Yes the auto setup does not spin the motor it just moves slightly to detect hall positions. Run on etc is normally related to the kp / ki values as does pulsing of speed. I would recommend you shoot an email to Kelly and include a link to your video.

    New Kelly pseudo FOC controller series

    The last one is easy... the number of poles just changes the RPM calculation and is not used for anything else. The others seem like the auto-sense has not worked as well as it should. I would run the process a couple of times ensuring the motor can spin freely with no load on it and the rotor...

    I like the look of that. As for the Winstons they are very temp sensitive. gotta be warm enough but not hot.

    New Kelly pseudo FOC controller series

    Izeman, I had this issue when I first set up the kart. I have a strange suspicion I found two Accel Release Time setting spots and I had to set them both to 1 for it to work. Not sure if that was just the odd version of the software I had or normal. Will check when back in the shed. I found an...
