    My1020 / Kunray / YaLU 1000 - 2000W motor ?

    I've started building this Pit-Bike-Drift-Trike & Snowmobile! I'm going to use a 72v MY1020 with my Sabvoton SVMC72150 so I can shove 150 amps into it but tune it as needed for 2 very different setups. As a drift-trike the power requirements will be very different to a snowmobile, and of...

    My1020 / Kunray / YaLU 1000 - 2000W motor ?

    I've received a new 3000w motor and the big brother 100 amp controller, which only costs slightly more than the 50 & 80 amp versions. I'm fitting heat sinks to the motor and installing this set-up on kart #16. I'll then take the kart to the track and see if the temperature stays under control...

    My1020 / Kunray / YaLU 1000 - 2000W motor ?

    I'm going to take advantage of the constant high speed air available to a go-kart with heat-sinks and ventilation holes. I went back to the kart track where I had tested the kart with the 80 amp controller, and cooling was greatly improved. I was able to do a 20 lap stint flat out, which takes...

    Good news about the cooked motor - it’s not cooked! I’ve had the motor checked out by the very helpful team at 'Recon Electrical and Motor Rewinders' and it’s electrically fine. Here’s what they had to say. “Electrically it seems fine. Insulation resistance test and surge tests came back ok...

    My1020 / Kunray / YaLU 1000 - 2000W motor ?

    Rare, medium or well done? The motor on the left is the one that heated up to 85c and smoked and stank. It still works but has lost a lot of power. The middle motor is the one I used at the kart track at the weekend, with a max temp of 72c. It has very minor discolouration and performance...

    My1020 / Kunray / YaLU 1000 - 2000W motor ?

    Had a fantastic day at Taumarunui Go Kart Track. My kart was about 3 or 4 seconds a lap slower than the 2-stroke karts, but for such a cheap system it was a lot closer than I expected. I had to keep an eye on the motor temperature as it would keep climbing, although I could get quite a few laps...

    My1020 / Kunray / YaLU 1000 - 2000W motor ?

    I may have been using the front nose cone on the kart during that test, and I've just realised how much that would deflect air around the kart instead of having a clear run to the motor. The nose cone is the same height as the motor so that could have a big effect on cooling. I need a wind...

    My1020 / Kunray / YaLU 1000 - 2000W motor ?

    I've managed to cook one of the motors. I had been using a 15T drive sprocket as that is the largest available for the MY1020. I got a custom 25T sprocket made to try and improve top speed. I got a slight increase in top speed but it didn't take long before the motor temp got over 80c and...

    That's an EM3EV battery, 20S10P of 30Q cells. I'm about to receive a 60v 20ah battery from UPP that I'm going to try.

    I'm making my Arrow AX6 #16 my track kart, with the Sabvoton SVMC72150. I'm getting some custom sprockets made to increase top speed. Blasting up and down the street isn't stressing the motor at all. Only 3 weeks till I can do some track testing!

    My1020 / Kunray / YaLU 1000 - 2000W motor ?

    I've wired up my Sabvoton SVMC72150 no problem to one of my karts. I've only done a quick test but the motor temp hasn't gone over 50c while running. It goes up to about 60c after stopping which suggests the motor cools quite effectively while I'm doing 65 km/h at full throttle. I was putting...

    My1020 / Kunray / YaLU 1000 - 2000W motor ?

    I'm converting 4 go-karts with MY1020 motors. I have 2 2000w versions and a new 3000w version running 72v and a 25-50 amp controller that was sold with the motor. I'm going to use 60v batteries for the others. The performance is a lot better than I expected from such a cheap set up, so I'm...

    kWeld - "Next level" DIY battery spot welder

    What an amazing thread! Fantastic stuff! I've never wanted to start building or repairing batteries, mainly because of the available spot welders being unreliable. This unit will be a real game changer, making battery work much safer. The question is, when will I be able to get a kWeld all...
