An internal fan-cooled electric motor (colloquially, fan-cooled motor) is a self cooling electric motor. Fan cooled motors feature an axial fan attached to the rotor of the motor (usually on the opposite end as the output shaft) that spins with the motor, providing increased airflow to the motor's internal and external parts which aids in cooling.
Motor capacitor. A motor capacitor[ 1][ 2] is an electrical capacitor that alters the current to one or more windings of a single-phase alternating-current induction motor to create a rotating magnetic field. [citation needed] There are two common types of motor capacitors, start capacitor and run capacitor (including a dual run capacitor ).
Watt steam engine. A late version of a Watt double-acting steam engine, built by D. Napier & Son (London) in 1832, now in the lobby of the Superior Technical School of Industrial Engineers of the UPM ( Madrid ). Steam engines of this kind propelled the Industrial Revolution in Great Britain and the world. The Watt steam engine design was an ...

These motors are sometimes called DC motors, sometimes EC motors and occasionally DC/EC motors. DC stands for direct current and EC stands for electronically commutated.. DC motors allow the speed of the fans within a fan coil unit to be controlled by means of a 0-10 Volt input control signal to the motor/s, the transformers and speed switches associated with AC fan coils are not required.
Stirling engine. A model of a Stirling engine showing its simplicity. Unlike the steam engine or internal combustion engine, it has no valves or timing train. The heat source (not shown) would be placed under the brass cylinder. A Stirling engine is a heat engine that is operated by the cyclic expansion and contraction of air or other gas (the ...
Radiator (engine cooling) Radiators are heat exchangers used for cooling internal combustion engines, mainly in automobiles but also in piston-engined aircraft, railway locomotives, motorcycles, stationary generating plants or any similar use of such an engine. Internal combustion engines are often cooled by circulating a liquid called engine ...
The federal government is committing nearly $10 million to saving right whales, the National Oceanic and Atmospheric Administration said on Tuesday. Nearly $7 million of that will support the ...
