AVR444: Sensorless control of 3-phase brushless DC motors
ثبت نشده
چکیده
Robust sensorless commutation control. External speed reference. Overcurrent detection/protection. Basic speed controller included. Full source code in C. Source code can be adapted to a new motor by changing parameters. Several I/O pins/peripherals not used for motor control. Can be used for other purposes, such as status LEDs, communication or user input. Works without modification on the pin and source code compatible devices ATmega48, ATmega88 and ATmega168.
