4. Key Problem-Solving Strategies
| Issue | Recommended Solution |
|---|---|
| Hard start / stalling | Use drivers with soft-start or add startup delay |
| Overheating | Add heatsink, reduce load, or optimize duty cycle |
| Unstable flow | Use closed-loop control (flow/current/pressure) |
| Excessive noise | Use FOC driver + low-noise pump structure |
| Poor battery life | Optimize motor efficiency and duty cycle |
