Sneak Peak @ The 72 Hp Electric Crosskart Powertrain

Just a quick video update showing the progress on the crosskart since the last upload. The drivetrain has been installed. In case you haven't read the details in my blog posts, the ME1616 motor is a 55 kW brushless, liquid cooled PMSM (permanent magnet synchronous motor). Connected to it via a 530 chain and 4.78:1 sprocket ratio is a 2007 Honda CR-V rear differential with matching cv axles. The battery will be LiFePo4 and somewhere between 10-12 kWh @ 96V, depending on how many parallel connections I can squeeze into the space that I've allowed for it. With regenerative braking and a total expected curb weight of 750 lbs when it's finished, that should provide close to 200 km's of range per charge in the trails.

I need to make some mounts for the rear (parking) brake caliper and the radiator, and then I'm going to focus on fitting the body panels and getting everything ready for paint this week. I'll upload another video covering this work in more detail for the build series on Sunday. The battery build and wiring will follow. Then the real fun starts lol. Until then, have a great week!
