Abstract An electric propulsion system is the heart of EVs. Its functional block diagram is shown in Fig. 5.1. Its job is to interface batteries with vehicle wheels, transferring energy in either direction as required, with high efficiency, under control of the driver at all times.

Journal of the American Institute of Electrical Engineers, 1921
This paper deals with the electric propulsion of practically all classes of vessels. The several types of electric drive are treated, in general, with special emphasis on Diesel-electric drive, as it is believed that this type of electric drive will be of most general interest, particularly to the inland section of our country, since it is especially ...

Electric propulsion applications
Conference on Advanced SEI Technologies, 1991Electric propulsion has matured to replace chemical propulsion for station keeping on virtually all major Soviet satellites. The Closed Drift Hall-type thruster was developed at the Research Institute for Thermal Processes, "NIITP", the Kurchatov Institute of Atomic Energy, "KIAE", and the Design Office "FAKEL".

Taking into account traffic flow, the greenhouse effect, pollutant emission, and noise emission, it seems that electric mobility is the best alternative for transport in urban areas. Nevertheless, as shown in Chap. 1, these unique characteristics are prejudiced by severe disadvantages regarding the sources of electric energy (Fig.

Proceedings of the Institution of Electrical Engineers, 1964
Electric drive is not advocated for all vessels, as its adoption can involve additional weight, complexity and cost. It can be justified where flexibility of machinery layout and operation, rapid manoeuvrability, constant-power characteristics and simple provision of power for large auxiliaries are features which can be utilised in service.

As we have seen in previous chapters, chemical propulsion systems are limited in performance by the energy stored in their propellants. This limitation can be overcome by using electric power available on the spacecraft (e.g., from solar arrays, nuclear reactors or beamed energy sources such as laser light or microwave energy transmitted to the ...

In the beginning of the 20th century, there were three candidate propulsion systems to replace the horse and buggy for personal transportation: steam, electric, and internal combustion engines. There were several reasons why the internal combustion engine won out. One was the invention of the electric starter first put in production in 1912. The driver
