The MorElectric system will use a belt-driven generator, which replaces the automotive alternator to provide the electrical 20drillpress power to drive the accessories integrated 20drillpress into the system. "Eliminating the gear or belt connection," Orr said, "allows for greater flexibility in locating electrically driven components, as they are no longer required to be engine-mounted'' The Morfllectric System also encourages the use of modular plug-in subsystems using high volume, cost-effective components, Orr said."MorElectric technology reduces various parasitic losses and removes the air conditioner thermal load from the radiator, diminishing the need to redesign radiator packages to handle higher thermal loads," Orr said. He added that the electric power could be leveraged for other purposes such as exhaust aftertreatment or for a variety of devices on the chassis, like a tailgate lift. The system can also supply 110 Va.c., 60 Hz power for hand tools or emergency lights. The marine market probably was a leader, given the presence of hot engines in cramped quarters that still required mechanics and operators to have access to all the nooks and crannies. There were also operational considerations in on- and off-highway equipment, such as an engine hot spot being exposed to engine or hydraulic fluids or a dirty operating environment and the resulting risk of fire.As a result, engine insulation blankets have been an accepted component in almost types of engines and equipment for many years. In on-highway, off-highway, stationary or marine uses, you usually find an insulation 20drillpress blanket or cover somewhere on the engine. [FIGURE 1-2 OMITTED]When the magnetic bearings are energized, the motor and impellers, which are keyed directly to the magnetic shaft, levitate. Permanent-magnetic bearings do the primary work, while digitally controlled electromagnets provide the fine positioning. Four positioning signals per bearing hold the levitated assembly to a tolerance of 0.00002 in. As the levitated assembly moves from the center point, the electromagnets'' intensity is adjusted to correct the position. These adjustments occur 6 million times a minute. The software has been designed to automatically compensate for any out-of-balance condition in the levitated 20drillpress assembly.SHUTDOWNS AND POWER FAILURESWhen the compressor is not running, the shaft assembly rests on graphite-lined, radially located touchdown bearings. 20drillpress The magnetic bearings normally position the rotor in the proper location, preventing contact between the rotor and other metallic surfaces. If the magnetic bearings fail, the touchdown bearings (also known as backup bearings) are used to prevent a compressor failure.
