New Fan Motors

Posted on September 20, 2011

Parker Hannifin’s Hydraulic Pump Division has introduced a new range of fan motors for heavy-duty applications. The M5 Series fan motors are rated for continuous performance at up to 4060 psi (280 bar) in mobile and off-highway equipment applications as well as portable power units.

The M5AS and M5ASF fan drive motors are engineered for high starting torque to withstand the higher pressures and speeds experienced in large mobile machines. Their independent-speed control capability enables the speed of cooling fans to be matched precisely to the operating load of the vehicle, facilitating greater overall system efficiency and minimized wear on parts, the company said.

The motors are also designed with an interchangeable rotating group and the same motor and piping location for left or right rotation, while double ball bearings are used to enable high-load capacity for flexible, direct-mounting capability. A patented 12-vane, double-lip cartridge design further provides a high level of fluid contamination resistance, Parker said.
