Sensorless BLDC motor control in Projects Posted July 13, 2013 Very cool project Tribes!! I was thinking of designing my own BLDC motor controller for an e-bike but I haven't had the time to get around to it. Your project is close enough where one could adapt it to work for an e-bike too with a few potentially minor changes. Thanks for the post! Also, are you heatsinking your MOSFETS? they might run a little warmer than you'd like that close together when running 20A.
