2. For RD model, pay attention to confirm the high frequency voltage value.

3. PWM intelligent speed regulation test needs to pay attention to adjust the frequency value.

4. Structural requirements: double ball bearing is elastic and consistent in elasticity; oil bearing structure: fan blade surface / buckle ring surface floating; hydraulic structure: fan blade sucking downward.

5. The shape / height of current waveform should be consistent.
