Motor Controllers Autopsy And Analysis

  Before I begin, be warned. A picture is worth a thousand words, and I dont have any pictures today, so this post is going to be a pretty big wall o text. If youre willing to brave my rambles, read on. Im currently finishing up my latest revision of ChibiTroller (v2.0), and since I first began controlling larger-scale bruushless things Ive gone through many different controllers. Most of which Ive blown up. This is a reflection and analysis of what Ive gone through so far, and what Ive learned.…

Frames Revamped: Chibi vs. Chipi

POTW Procrastination Edition I did it! I got rid of all the waterjet cut bits! Heres the bare chibikart frame.I was trying to keep too much of it the same. So I replaced everything.   And heres what I got. Its the same thing, just welded steel instead of aluminum extrusion. And its a bit heavier, but not by too much (thin wall tubing is nice like that).

But whats better than the grinding, powerful not-launch of a sensorless drive? The smooth, terrifying launch of a sensored one. Id been thinking about how to achieve this on a vehicle, especially after seeing TinyKart at NYC Maker Faire. And then I forgot.Charles recently posted about adding sensors to sensorless motors and driving them with Jasontrollers. And I realized that it was what I wanted to do,…

What The Hell Has Been Going On Here?

Motor Controllers Autopsy And Analysis I mean really, its been four months. Thats not cool. Which means now I get to try to sum up a whole lot of things in as few words as possible. This should be interesting. ChipiKart I did finish it. See? It even ended up looking somewhat presentable with the Mercedes 300SL body on it. I ended up using 120A Kelly controllers on it, as the hacked jasontrollers just werent cutting it. I regret nothing. Proper controllers are a thing of beauty. With it being…
