Electrical Design Improvement for Hot-Swappable Fan in 1U Server Rack
Sanyo Denki over the years designed innovative high-performance fans for niche markets. The latest San Ace 40 9HVA type is designed with customer requirements in mind. An example application is hot swappable fan in 1U server rack. There are severe design challenges for a cooling fan to move a large volume of air under back pressure. To achieve high static pressure performance, Sanyo Denki engineers prioritized on significant speed improvement and optimizing the shape of the frame and impeller, but it is just not enough: high speed and efficient motor are also required to move air at turbulent speeds.
The improved electrical design aspects of the newer Sanyo Denki 9HVA type need to be highlighted. With the help of newly designed 3-phase drive motors and advanced control and circuit design, higher fan speed can be achieved from high-frequency switching. Click below to read more.
