Bison, a motor technology firm, has announced the issuance of a patent for the RAM Reverse Air Movement Blower Motor. This technology overcomes the performance shortcomings of traditional thru-flow air blower motors through its novel design, the company explained.

RAM technology is expected to transform various air moving applications, catering to industries that prioritize lower operating temperatures, enabling achievement of reduced noise, and extended motor life. This technology can reportedly 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 relies on a reverse airflow design. The motor side is only exposed to ambient air intake, ensuring optimal cooling even in near-sealed conditions. This reportedly 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 reported 6.5% reduction in decibel levels and a 48% reduction in Sones compared to traditional thru-flow motors. RAM technology also completely removes the need for a leak path at low flow conditions, leading to increased product performance and reduced noise.

Another benefit of RAM technology is its versatility. The motors support straight air exit, peripheral and reverse airflow, thereby providing solutions for assorted applications. The technology can also significantly reduce carbon dust emissions by applying V0 rated foam to surround the motor, which improves product performance and also helps minimize noise.
