The application kit can be run by supplying 12V to the connector X1 on the application basis
board. The Atmel
enclosed BLDC motor featuring a back EMF feedback method. The three windings of the
BLDC motor need to be connected to the three phase clamps U, V, W, see
12.
After powering up, the BLDC motor starts operation automatically. The target speed is set up
based on the potentiometer speed.
Additional software is available on the enclosed CD for evaluation purposes and is described
later in this document.
