    Undergrad When the motor is working harder, it needs to rotate faster.

    So when the pressure increases causing the RPM to increase what sort of disadvantages am I looking at (besides the blower being louder)? Do you think I will experience any additional wear and tear on the motor because the rotor is spinning faster or not really since the same amount of power is...

    Thanks for your response. I should probably elaborate a bit more on how this is being used. The blower is installed in an HVAC environment with metal ducting. Increasing the duct length, turns or shrinking the diameter increases static pressure. The blower itself isn't increasing pressure on...

    Hi all, long time reader first time poster here. I have a DCBL blower motor that has a fixed wattage at each speed level. I noticed that when I increase pressure (say from 0" SP to .1" SP) the RPM increase and the CFM (airflow) decrease. I understand that CFM will decrease with increased...
