A fractional-horsepower motor (FHP) is an electric motor with a rated output power of less than one horsepower (745.7 W) (the term 'fractional' indicates less than one unit). There is no defined minimum output, however, it is generally accepted that a motor with a frame size of less than 35mm square can be referred to as a 'micro-motor'.
In 2003, Mercedes-Benz added the C 180 Kompressor, followed by the C 200 compressor in 2003-2007 (187 hp), and finally the C 160 Kompressor in 2005. The C 230 SportCoupé was powered by a 2.3-litre supercharged, four-cylinder motor. It offered 143 kW (192 hp) and 270 N⋅m (200 lb⋅ft) of torque.
In air conditioning, an inverter compressor is a compressor that is operated with an inverter. In the hermetic type, it can either be a scroll or reciprocating compressor . This type of compressor uses a drive to control the compressor motor speed to modulate cooling capacity.
The rise in air and temperature ratio means compression does not follow a simple pressure to volume ratio. This is less efficient, but quick. Adiabatic compression or expansion more closely model real life when a compressor has good insulation, a large gas volume, or a short time scale (i.e., a high power level).
An AC motor is an electric motor driven by an alternating current (AC). The AC motor commonly consists of two basic parts, an outside stator having coils supplied with alternating current to produce a rotating magnetic field , and an inside rotor attached to the output shaft producing a second rotating magnetic field.
As an example, a 250 HP compound compressor is a large piece of equipment that generally requires a special foundation, building accommodations and highly trained riggers to place the equipment. On the other hand, a 250 HP rotary-screw compressor can be placed on an ordinary shop floor using a standard forklift. Within industry, a 250 HP rotary ...
A compressor map is a chart which shows the performance of a turbomachinery compressor. This type of compressor is used in gas turbine engines, for supercharging reciprocating engines and for industrial processes, where it is known as a dynamic compressor. A map is created from compressor rig test results or predicted by a special computer program.
A variable-speed drive (VSD) air compressor is an air compressor that takes advantage of variable-speed drive technology. This type of compressor uses a special drive to control the speed ( RPM ) of the unit, which in turn saves energy compared to a fixed speed equivalent. [ 1 ]
