Description

This reference design offers a universal motor control design for TI’s AM263x Arm® based MCUs. The design shows how to use AM263x MCUs for various types of FOC motor control techniques, such as sensorless (eSMO) and sensored (incremental encoder, Hall sensor). The design supports two main hardware setups: a low-voltage setup using AM263x LaunchPad™ with 3PHGANINV BoosterPack™ and a high-voltage setup using AM263x controlCARD™ with TMDSHVMTRINSPIN motor control kit. The documentation also covers instructions on migrating the design to a custom board and porting the project to new devices.
