I got a few vacuum motor questions and i think im in the right place to ask them 1.What would be the maximum CFM a vacuum cleaner motor could move? (This is with an open motor meaning that its no longer a vacuum cleaner but just the motor so theres nothing to slow the airflow down) 2.If you used a suction cup(like they do on those stupid vacuum cleaner commercial to pick up a bowling ball) What would be the maximum weight a vacuum motor could lift? 3.I have mounted 6 vacuum motors to a wooden box so all the motors will suck air out of the box. With each motor thats turned on would the sucking power be doubled? 4. If all 6 motors were on what would the max CFM and max weight it could lift be? If anyone needs pics to see what im talking about just ask!!
