Three-Phase Brushless/PMSM High-Current Motor Control Solution with SPI

Texas Instruments

This reference design demonstrates a motor control solution for spinning three-phase brushless DC (BLDC) and brushless AC (BLAC) - often referred to as permanent magnet synchronous (PMSM) - motors featuring the C2000™ Piccolo™ microcontroller and the DRV8301 three-phase motor driver. It provides three half bridge drivers: each capable of driving two N-type MOSFETs: one for the high-side and one for the low side. It supports up to 2.3A sink and 1.7A source peak current capability and only needs a single power supply with a wide range from 6V to 60V. The reference design features a high-performance: power-efficient: cost-effective platform that speeds development for quicker time to market. Applications include CPAP and pumps: e-bikes: e-scooters: medical pumps and drills: power tools: and robotics. This is a high performance: power-efficient: cost-effective sensorless field - oriented control (FOC) and sensored/sensorless trapezoidal commutation platform that speeds development for quicker time to market. This reference design is based on the DRV8301 evaluation kit.
