All-Terrain Scooter électrique. At the beginning of the 2011/2012 school year, my school's robotics team decided to finally dismantle some old FRC robots that had been collecting dust for six or seven years.
We had no use for all the parts we stripped off the robots, so I generously relieved the team of some of these parts, including six Victor 884's, six CIM motors (4x 2.5", 2x 3"), 2 AndyMark Toughbox gearboxes, some #35 roller chain, and assortment of sprockets, some steel shafts and shaft collars, a 1/4" by 4" by 3' aluminum plate, 1" aluminum U channel, 1/8" polycarbonate sheet.... Anyways, while looking up the CIM motor curves, and trying to figure out by how much I could over-volt them, I ran into this, which at one point used a pair of CIM motors. That vehicle then led me to these. Compteur de vitesse Bike Arduino. Panier de vélo en bois. DIY Electric Bike Conversion.
Here is the kit used in the conversions.
You have a rear wheel motor, controller, thumb operated throttle, on/off switch, brake levers with kill switches (not used), and battery to control cable. The motor in this kit is a 500 watt continuous, 1200 watt peak power geared motor especially suited for hills. This motor requires a 22 Amp continuous controller. The brake levers had kill switches on them. Since the throttle is thumb operated, the kill switches and extra wires did not seem necessary. The kits also came with nylon battery bags. Cost of Kit: $350 Controller: $ 50 extra Total cost for the conversion including the kit, battery, and parts was about $950. Électrique Motorsport EV Pièces. Solaire Trike Powered.
Find a lightweight vehicle with low rolling resistance.
A two, three or four wheeler will do, depending on how much work you want to do, but the concept is the same. Four wheeled vehicles may be regulated under different laws. Of course the best vehicle is one that you already have, if you happen to have a three or four wheeled pedal powered vehicle. In the interest of simplicity, a three wheeler was chosen for my project. This Schwinn Meridian Trike was $250 new, readily available locally, and the basket provides a convenient location for batteries and solar panels with minimal fabrication.
The first thing to be done was completely disassemble the trike and paint it a bright 'fern' green. Before painting the frame, I used this stage as an opportunity to reinforce the frame where the Batteries were going to mount. High pressure (65psi) tubes were equipped and the Trike was meticulously assembled in order to minimize rolling resistance. Chibikart: Rapid-Prototyping a Subminiature Electric Go-Kart Using Digital Fabrication and Hobby Components. I hope everyone has found this Instructable a great help to starting in the world of building mechanical projects or furthering their existing ones!
This has been a veritable BOOK (seriously, shorter books have been written). Writing a comprehensive how-to has never really been my style, as I usually try to encourage exploratory learning and finding it out yourself. However, this build of Chibikart was my chance to combine that style of "guidebook" writing with an immediate application. I hope it has turned out well. Many parts were left deliberately vague, and parts some times magically materialized, to encourage filling in the gaps. My design mistakes were included in the open, as part of instructions (with advice to avoid them, of course), to show that even if you think you know what you're doing with this super simple thing, there are always things which can come up that you haven't thought of before. I always include this at the end of my Instructables, and this is no different! Homemade 100 CV Contrôleur de moteur pour une voiture électrique.
Remorque à vélo Aevon KIT L80. Contrôleur de moteur cc pour vélo électrique. I designed this controller for my Crystalite Sparrow 48V electric bicycle hub motor.
The core function of a DC motor controller is to periodically read the throttle setting and adjust the current being supplied to the motor. It does this with a technique called pulse-width modulation or PWM (more on this later). Note1: This is a relatively advanced instructable. Don't attempt it if you don't have experience with power electronics. The voltages and currents used in this project can be dangerous and appropriate safety precautions must be used. Note2: In addition to the 48V battery voltage, this controller requires a 12V power supply.
Note3: This controller is over-designed for this application.
