4.2 Connection Details

Figure 4-2 shows the power supply and motor connections made to the DRV8317HEVM in order to spin a 3-phase sensored or sensorless Brushless-DC motor.

A 4.5-V to 20-V power supply or battery is connected to the VBAT and GND terminals. The three phases of the BLDC motor connect directly to the OUTA, OUTB, and OUTC terminals of the screw terminal provided on the DRV8317HEVM.

For sensored applications, the Hall sensor outputs need to be connected to the respective Hall connector terminals on the DRV8317HEVM.

Figure 4-3 shows where the Micro-USB cable is plugged in to the LAUNCHXL-F280049C to provide communication between the LaunchPad firmware and GUI as well as the correct installment of the DRV8317HEVM to the J1/J3 and J2/J4 headers of the LaunchPad.
