SENSORLESS-BLDC-MOTOR-RD
3. Sensorless Motor Reference Design Demonstration
The Sensorless BLDC Motor Reference Design includes everything you need to set up a Sensorless BLDC motor
demonstration. Connect the BLDC motor to the Sensorless BLDC motor control board following the wiring chart for
the Anaheim Automation BLY171S-24V-4000 motor as shown in Table 1.
Connect the 12 V universal ac/dc power adapter to the dc supply (P1) on the Sensorless BLDC Motor Reference
Design Board. Rotate the SPEED knob fully clockwise. Press the START button on the Sensorless BLDC Motor
Reference Design Board. The motor will start running. Notice that the motor will first align and then smoothly speed
up to the minimum closed loop running speed. Rotate the knob counter clockwise to adjust the speed of the motor.
Press the STOP button and the motor will stop spinning.
