详细说明： This project aims to create a fully open-source Brushless Drive Controller. Where is the hardware --------------------- The hardware design files got split into a separate repository on github called open-bldc-hardware. Current design -------------- The current design uses an STM32 microcontroller, Allegro halsensor based current sensors, IRS2101 bridge drivers. This combination will allow: - Vectorfield control for smooth and very exact torque and speed control - N-Mosfet only powerstage design to increase efficiency - Many different interfaces (PPM, I2C, CAN, USART, USB) for interfacing Targetted features ------------------ * 3/4C LiPo cell support * 20A constant power output or more * Active freewheeling * Adjustable timings * Active break with power pushback to the batteries? * Different interfaces: ** PPM ** Serial ** I2C ** CAN * As small as possible; current design is 60x26mm (may and probably will change in the future) * Software license: GPL, version 3 or later * Hardware license: CC-BY-SA 3.0 * Rotation speed controller * Detatchable powerstage * Vector control support * Hall sensor support Inspiration references ---------------------- Some application notes were consulted while designing the circuits of the drive conntrollers: http://www.atmel.com/dyn/resources/prod_documents/doc7518.pdf http://www.atmel.com/dyn/resources/prod_documents/doc7658.pdf Also some inspiration was taken from the brushless controllers designed by Holger Buss for the Mikrokopter project (http://www.mikrokopter.de). But the design is constantly changing and moving away from designs that were considered as inspirations quickly. For more information take a look at http://open-bldc.org. A lot of progress reports are posted on http://www.esden.net, so this page may be worth a look too.

Feel free to use everything here as you wish! :) ...展开收缩
