Micro 3-Phase Motor Controller


It is always exiting to receive PCB’s. I am looking forward to work on this one because it is a very small (40 x 12 mm) 3-phase Motor controller. It is designed to communicate using RS-X and control the motor in the background.


The block diagram show the components on the board. Communication is RS485, Motor Algorithm is in this case a matter of ticking speed/direction and configuring the I2C based DRV10983 that also contains the PWM drivers. Have to wait a few more days on DRV10983 and we will try spinning this baby.
