Using the dsPIC30F for Sensorless BLDC Control
This application note describes a sensorless BLDC control application using the BEMF detection method. The dsPIC ADC is used to detect the BEMF voltage. The source code has parameters to adjust the open loop startup sequence and also the closed loop operation of the motor. A GUI is available in the MPLAB IDE to help set the parameters. See GS005 for more information about the GUI.
The AN901 application is written in C language for a dsPIC30F6010 or a dsPIC30F6010A device.
