In exchange you will be asked to take photos and make videos of your work in order to showcase your project.
How much : Thanks to our partnership with La petite Rennes we can provide you with a battery free of charge, a battery charger and an electrical bike engine. How : By inserting an engine in the wheel using a Dibond flange (Documentation in the works) and by controlling the engine with a dedicated electronic card (VESC). Realization of the mechanical part (Third version) : Mécanique V3įor who : For all individuals who wish to enhance their mobility using an electrical bike engine.įor what : For children's bikes, hemiplegic quadricycles, scooters to tow wheelchairs ( trotti).The second version is similar to the third version.Realization of the mechanical part (First version) : Mécanique V1 NOTE : This solution is not retained because it is too difficult to set up and remove.Discussion channel of the project on Framateam.In the program, when you have a number with a decimal, you must use a comma (example: -0,10) and not a dot (-0.10).Moreover, the implementation of a master switch that cuts the main power (Safety circuit breaker) will hold the engine at rest. There is way to facilitate reversing through special settings indicated by the acronym (M.Ar). When you attempt to reverse with your installed device, the engine opposes a resistance, this is supposed to happen. Reversing is not possible with this type of engine./!\ Do not unplug the engine when the battery is plugged in !.Merci/Thanks/Danke Schön Benjamin Vedder :) Warning The VESC card and the VESC Tool were designed by Benjamin Vedder VESC Project Configure an electronic VESC board with a dedicated program (VESC Tool) in order to control an electrical bike engine with an electrical scooter type accelerator throttle.Make the wiring and the required electrical connections to use this electronic board in order to control an electrical bike engine (as well as other types of engines such as DC, brushless).
This project presents in details how to configure a VESC board ( Vedder Electronic Speed Control) :
The device provides 16 general-purpose I/O ports (GPIO) with the 5 V tolerant capability, one 12-bit analog-to-digital converter with up to 9 channels performing conversions in a single-shot or scan modes, 5 synchronizable general-purpose timers and supports an easy to use debugging serial interface (SWD). The STSPIN32F0 device also features overtemperature and undervoltage lockout protections and can be put in the standby mode to reduce the power consumption.
It has the write-protection and read-protection feature for the embedded Flash memory to protect against unwanted writing and/or reading. The integrated MCU (STM32F031C6 with extended temperature range, suffix 7 version) allows performing field-oriented control, the 6-step sensorless and other advanced driving algorithm including the speed control loop. A comparator with a programmable threshold is integrated to perform the overcurrent protection. The integrated operational amplifiers are available for the signal conditioning of the analog Hall-effect sensors and the shunt resistor signal. An internal LDO linear regulator provides the supply voltage for gate drivers. An internal DC/DC buck converter provides the 3.3 V voltage suitable to supply both the MCU and external components. The high- and low-side switches of same half-bridge cannot be simultaneously driven high thanks to an integrated interlocking function.
It embeds a triple half-bridge gate driver able to drive power MOSFETs or IGBTs with a current capability of 600 mA (sink and source).
Description The STSPIN32F0 is a System-In-Package providing an integrated solution suitable for driving three-phase BLDC motors using different driving modes.
