Please help me recommend a brushless DC motor development kit

Please help me recommend a brushless DC motor development kit, that is, including the controller, procedures and motors.
Specific requirements:
1, the controller chip needs to be KEA128 or 64, if not， others are OK，but its performance and programming is closer to the KEA128;
2, the program needs to be for BLDC with position hall sensors;
3, the program needs to achieve forward, reverse, speed regulation , other basic functions and some commonly used algorithms;
4, driven motor and power circuit can be changed, the latter need to test the motor of different power levels;
Thank you very much.

Hi, Simith,

Pls refer to the website for KEA family application to control BLDC.

3-phase Sensorless BLDC Motor Control RD|NXP

If you use Hall sensor to detect position of rotor, as you know that the KEA has three FTM modules, FTM0 can be used to generate 3 pair PWM signals, FTM1 and FTM2 can be used to detect Hall signal with capture function so that rising/falling edges of three hall signals can be used to trigger interrupt, compute the speed. You can connect 3 hall signals to FTM1 or FTM2 channels for example FTM1_CHx, it is okay. For forward, reverse, speed regulation, it is dependent on software.

I think any KEA family is okay to control BLDC.

Hope it can help you
