Abstract

Field oriented control (FOC) is getting popular in BLDC motors for best-in class acoustics and load-dynamic performance, however this needs intense tuning effort to get the best motor performance. MOTORSTUDIO is an easy-to-use graphical user interface (GUI) that simplifies the tuning process of TI's Brushless DC (BLDC) motor drivers to reduce device evaluation and product development time.

SmartTune is an intelligent auto configuration tool in MOTORSTUDIO. This tool helps users to tune startup time, acceleration, efficiency and control loop parameters for the BLDC motor drive in 2 minutes, by taking only 3 parameters which are system voltage, rated motor current and rated motor speed.

This document firstly introduces the application scenario of SmartTune and the issue users can encounter during setting up. Then, detailed tuning steps are listed so that users can follow them to set up and spin the motor. Finally, tips for setting SmartTune parameters are provided to help users eliminate faults caused by inappropriate parameter input.

This document is currently applicable for the following devices:
