Sensorless BLDC motor control on MCXA153

This application note demonstrates how to implement the six-step commutation control of brushless direct current(BLDC) motor on the MCXA family of MCUs. The NXP Freedom board FRDM-MC-LVBLDC is used as a hardware platform for the motor control reference solution. The hardware-dependent part of the motor control software is addressed as well, including a detailed peripheral setup and driver description.

3.2 Step 2

Connect the FRDM-MC-LVBLDC shield to the J1~J4 arduino connector of FRDM-MCXA153 board. Connect the 3-phase wire of the motor to the J7 connector on FRDM-MC-LVBLDC according to phase sequence(White wide--phaseA; Bule wide--phaseB; Green wide--phaseC). Power the FRDM-MC-LVBLDC board with a 12V adaptor.

Compile the project and use a USB cable to connect to the EVK board via J15 connector. Use MCU-LINK to download program into MCU.
