Electrical Designer: Kenny Na
Description
BLDC motor controller compatible with 3S systems. Will initially be standalone, connecting to 12V -> 5V @ 4A Buck Converter + ELRS Board externally and then later physically integrated into another board revision for an all-in-one fixed wing solution.
Depending on the cost and performance of the board, it may be integrated elsewhere.
Documentation inspired by 12S ESC.
This board design is part of Kenny’s WARG EE Fall 2024 co-op.
Requirements
Should be powered by a 3S (12V) battery input.
In the context of integrating with the ELRS board, an XT60 connector should be provided, and additional 5V, GND, and PWM headers should be placed. The ESC’s “BEC” is already integrated into the ELRS board.
Must use the AM32 open-source firmware for motor control. (https://am32.ca)
This uses a sinusoidal algorithm to control the BLDC. (no FOC)
Has a strict MCU compatibility list (we would preferably use a smaller ST chip)
