In recent years, cells and batteries—especially cells—have become available in many different sizes and shapes besides the old cylindrical cells, transistor batteries and lantern batteries. In this article, you will learn about three types of miniature cells and batteries. Silver …
Electric cars are making big waves in the automobile world. These noise-free, pollution-free and high-performance vehicles are expected to make their I.C. engine counterparts obsolete by 2025. This video will unveil the hidden technologies behind the Tesla Model S, which …
The Stroboscopic Effect in Fluorescent lamp is a phenomenon which causes running or moving equipment to appear stationary or appear to be operating slower than they actually are. Fluorescent materials when subjected to electromagnetic radiations of a particular wavelength, get …
A DC motor is an electrical machine that converts electrical energy into mechanical energy. The working of DC motor is based on the principle that when a current carrying conductor is placed in a magnetic field, it experiences a mechanical …
Armature reaction in alternator is the effect of armature flux on the field flux (i. e., rotor ampere-turns). Read this article to learn more. We have already discussed the effect of armature reaction on the air gap flux in DC …
Electric Motors need maintenance regularly in order to avoid failure and prolong their lifespan. Generally, motors and motor parts should be maintained and tested at least every 6 months. Then only it is possible to maintain a motor’s life and …
Before going to the operation and characteristics of split-phase induction motor we should first understand why single phase induction motor is not self-starting. To make a single-phase induction motor self-starting, we should somehow produce a rotating magnetic field. This may be …
What is an Electric Locomotive? An “Electric Locomotive” is a railway vehicle that can move along rails and push or pull a train attached to it using electric power drawn from an external source, usually from overhead cables or a …
Speed control of dc motor is achieved using different methods. There are three types of dc motors. For each of them, there are different methods of speed control. Each of them is discussed in this article. The principal advantage of …
