2022-10-25 (Tu) PoweredInlineSkatesRev2 New design

I learned a lot from building the first PoweredInlineSkates. I didn't like how tall they were because it was hard on my ankles, but I could see over cars. A 350-watt motor designed for toy scooters was fun, but it didn't bring me to the speed I wanted and didn't handle inclines well. My next model had to be more powerful and lower to the ground. I thought about buying a 500-watt scooter wheel and mounting it behind my heel and up so it wouldn't be any higher than regular skates, but this meant building a custom wheel rack again.

The option I liked better was investigating high-power brushless motors, which always interested me, but they had an intimidating learning curve. I sought out some motor/controller pairs, and many already claimed to be suitable for powered longboards, which would be perfect since I'll be using similar wheels. As I tried to make sense, I researched terminology and options to top the curve. When I felt confident, I bought a motor, controller, and longboard conversion kit.

I wanted to add a powered wheel behind my existing skates. I measured the distance between my wheels and took a picture. In QCAD, I placed circles at the correct spacing, then scaled the image to fit. The wheels don't match perfectly due to parallax, but my drawing is as accurate, and I can make it. I traced the boot so I wouldn't try to build anything in that space.

I drafted the rest of the parts, like the motor, the conversion kit pulleys, and the skate wheels. I will remove the brake for this build. The plate I'm designing will use long bolts acting as the two rear wheel axles, which will also become plate supports. I added more spacers throughout for stability. The motor is not directly above the powered wheel but forward and slightly lower to save space. I ordered eight new wheels, so I have uniformly sized parts and don't have to worry about the new wheel being taller than the rest.
