Overview

This reference design describes a motor-control evaluation kit for spinning 3-phase brushless DC and brushless AC (BLAC) often referred to as permanent-magnet synchronous (PMSM) motors with example of sensorless field oriented / vector control (FOC). The implementation leverages the DRV8301 gate-driver IC as well as the TPS65381 power-management IC (PMIC). This reference design can be used as a high-performance, power-efficient, cost-effective platform to speed up development of PMSM control algorithms.

Features
  • Reference design for managing interfaces to TPS65381 PMIC and DRV8301 gate-driver ICs
  • Encoder-based FOC with redundant sensorless-speed estimation
  • Speed and torque control loops
  • Follows TI MotorWare and HALCoGen conventions
  • Leverages ARM CMSIS math library
