Other Parts Discussed in Thread: DRV10983, DRV10975
Issue: The DRV10974 stops after starting for a few seconds.
1. The ADV=59k, RMP=7.32K, CS resistance is set from 120k to 10k and it doesn't work.
The motor accelerates for a few seconds after starting, then stops, and then automatically accelerates for a few seconds after a few seconds of rest.
2. The CS resistance is restored to 120k and the ADV resistance is adjusted from 10k to 180k, the problem still remain.
3. Rated at 12 V, turning the supply voltage down to 6 V, 8 V, 10 V is not useful, the problem still remain.
Due to limited equipment, BEMF Constant cannot be measured, the following motor parameters are provided:
a. Two-phase resistance: 5.2 ohms
b. Two-phase inductance: 920uH
c. Rated operating voltage: 12 V.
d. The motor has 9 coils, 3 pole pairs UVW
The customer would like to know what's the possible reason for that, does this chip not support this motor? If not, could you please recommend a model?
Thanks a lot!
