I bought C28207F Lounchpad and BoostXL- DRV8301 to learn and test the functionalists of Motorware and to run the Simulink model described here. Therefore, I bought additionally:
- BLDC motor with these properties (typical operating voltage 24V, till max 48V, current 1.8A, Peak current 5.4A)
- Universal power supply with these proprieties (output: 12V / 15V / 18V / 19V / 20V / 22V / 24V DC
• output current:
12V: 2250 mA
15V: 1800 mA
18V: 1500 mA
19V: 1400 mA
20V: 1350 mA
22V: 1200 mA
24V: 1000 mA
• Max : 27W)
I set up firstly the power supply to 15 V and powered the DRV8301 board. I connected additionally the 3 phases pins to the motor terminal. When I loaded the executable file, the motor firstly did not react. I thought that the power supply is not set up properly. Therefore, I tried several set up between 17-24V. The motor started to react, tried to turn (2-3 times) and then locked. When I turned off the power supply I noticed shortly an electrical arc. I thought that it was either a current or voltage spike. But I set up the power supply under the nominal values of both the board and the BLDC motor. The motor tried by these set ups to turn (2-3 timed) and then locked again and the fault LED starts glowing red. After seconds the motor was very hot. I turned off immediately the power supply and thrown out the motor 3 phase pins form the DRV8301 board. When I powered on the board form the power supply the Fault LED remains glowing. When I powered on the board form the PC via USB cable the Fault LED is turned off and the 3.3V LED turned on to yellow.
Now my question is how can I check if the DRV8301 board, or the motor or both got damaged? and WHY did I see electrical arc when I powered on the board form the power supply within the allowed range?
