An internal fan cooled electricmotor colloquially, fan cooled motor is a self cooling electricmotor . Fan cooled motors feature an Fan mechanical axial fan attached to the Rotor electric 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. Image Smallfancooledmotor.jpg 250px right Uses Fan cooled motors have many common uses in motors that either produce a lot of heat or have poor airflow because they are always stationary or in an enclosed space and require a compact cooling system. They are common for industrial uses ref http www.frasers.com public searchResults.jsf jsessionid AA6F5C172D9346CF0319292AF52D3B5A?dimensionName Motors Fan Cooled&guided true&ProductID 16669 ref , household appliances such as blenders and mixers, power tools such as drills and rotary tools, and radio controlled car s ref http www.traxxas.com products accessories trx accessories titan12t.htm ref Advantages Attaching an internal fan to a motor is a fairly simple way to cool it. Since a fan cooled motor always provides airflow over itself regardless of whether it is stationary or partially enclosed, it is more effective than using a heat sink in applications with poor airflow because heat sink s usually require air to be flowing over them for maximum effectiveness. Internal fan cooling also takes up far less space than TEFC external fan cooling or water cooling . Disadvantages All fans generate noise, something that may not be desired in a motor, and Drag physics drag on their power source. Also, like any device with a Fan mechanical fan , increased airflow through the motor can cause increased dust build up, which could potentially hinder the motor s operation.

T Motor was the name given by the New York Central to its ALCO GE T1a, T1b, T2a, T2b, and T3a electric locomotives. After the New York Central was merged into Penn Central , Penn Central continued operating them. History ALCO and GE co built T Motors from 1913 to 1926. T Motors were only used on the third rail territory from Grand Central Terminal on to the Hudson and Harlem Divisions. They were the powerhouses of the GCT Division. T Motors hauled everything from commuter trains to the 20th Century Limited . At Croton Harmon on the Hudson Division, T Motors would be switched with steam, and later, diesel motive power to continue the journey. During Penn Central management, Penn Central was painted in NYC lettering on the engines. Slowly, T Motors were replaced by New York, New Haven and Hartford FL9 s on the Penn Central roster.

An electrostatic motor or capacitor motor is a type of electricmotor based on the attraction and repulsion of electric charge . Usually, electrostatic motors are the dual electronics dual of conventional coil based motors. They typically require a high voltage power supply, although very small motors employ lower voltages. Conventional electric motors instead employ magnetic attraction and repulsion, and require high current at low voltages. In the 1750s, the first electrostatic motors were developed by Benjamin Franklin and Andrew Gordon inventor Andrew Gordon .
