Rm - Motor phase resistance between phase to phase;
Lm - Motor phase to phase inductance between phase to phase;
Kt - Motor BEMF constant from phase to center tape;
fFG_max - Maximum electrical frequency. Maximum motor speed can be calculated from:
If FGS = 1, RPM = (fFG_max × 60)/ number of pole pairs
If FGS = 0, RPM = (fFG_max × 120)/ number of pole pairs
8.2.2 Detailed Design Procedure
1. Refer to Design Requirements and make sure your system meets the recommended application range.
2. Refer to the DRV10963 Tuning Guide and measure the motor parameters.
3. Refer to the DRV10963 Tuning Guide. Configure the parameters using DRV10963 GUI, and optimize the
motor operation. The Tuning Guide takes the user through all the configurations step by step, including: start-up
operation, closed-loop operation, current control, initial positioning, lock detection, and anti-voltage surge.
4. Build your hardware based on Layout Guidelines.
5. Connect the device into system and validate your system solution
