Emerson Special Products Div (ESPD) has developed a wet and dry vacuum cleaner that can pick up 79 lbs of nails in one minute or a bushel of sawdust in 19.6 seconds. The technology is based on a switched reluctance drive. ESPD engineers used CAD simulations to model the control circuitry and the inertia of the motor. ESPD has also introduced a ceiling fan with a K55 motor that uses 2,244 ft of copper wire to ensure efficiency.
Switched reluctance motor expands the potential for workshop vacuum cleaner.
With more than 25 years of experience producing wet and dry workshop vacuums for Sears, Chicago, the Emerson Special Products Division (ESPD), St. Louis, recognized that the existing technology of universal motors has certain limitations that their customers would like to see addressed.[Read more…] about The Most Versatile Powerful Wet And Dry Vacuum
