RAM Reverse Air Movement Blower Motor

April 18, 2024


KENT, OHIO – Bison, a leader in innovative motor technology, proudly announces the issuance of a patent for the revolutionary RAM Reverse Air Movement Blower Motor. This cutting-edge invention, spearheaded by esteemed Senior Director of Technology, David Finkenbinder, overcomes the performance shortcomings of traditional thru-flow air blower motors through its novel design.


RAM technology is poised to transform various air moving applications, catering to industries that prioritize lower operating temperatures, enabling achievement of reduced noise, and extended motor life. This innovative technology can benefit applications from industrial fume evacuation, floorcare for commercial and residential use, paint sprayers, aerospace air movement, surgical smoke evacuation, and hand dryers.


Unlike traditional thru-flow motors that face overheating challenges, RAM technology employs a unique reverse airflow design. The motor side is only exposed to ambient air intake, ensuring optimal cooling even in near-sealed conditions. This innovation eliminates the need for costly thermal protection or energy-inefficient bleed holes, enhancing reliability, sound performance, and overall motor life.


Motors with RAM technology operate at significantly cooler temperatures, enhancing brush life, commutator performance, and overall reliability. The technology achieves a remarkable 6.5% reduction in decibel levels.
