We need a sensorless motor control by using ic L6230. Please see the attached Datasheet of L6230 and make the schematics design using a microcontroller to control the L6230. And make the programming for microcontroller such as L6230 can be used to drive a BLDC Sensorless motor. Also we need one output signal from MCU before it starts motor such as we can power on external power supply for motor.
Also we need one button for Start, Stop, Speed Up, Speed Down. If you have some knowledge in making Remote Cbrontrol so you is very welcome to give suggestions on creating a onboard sensor for remote control.
Remember in this project you doesn't have to create PCB Layout. You only make schematics & programming.
