Special electric machines have a large field of application and actual requirements for electromechanical systems clam new and very performing solutions. There are a lot of papers on this subject‚ but anytime is mandatory to do something else to help users to develop high level systems. Main intention of the authors for this paper is to present a modality to analyze and to design a new solution of electric machine only trough finite element method. Actually‚ the users are asking for very performing

5.7 Necessity of D.C. Motor Starter At starting‚ when the motor is stationary‚ there is no back e.m.f. in the armature. Consequently‚ if the motor is directly switched on to the mains‚ the armature will draw a heavy current (Ia = V/Ra) because of small armature resistance. As an example‚ 5 H.P.‚ 220 V shunt motor has a full-load current of 20 A and an armature resistance of about 0.5 . If this motor is directly switched on to supply‚ it would take an armature current of 220/0.5 = 440 A which

There are three standard field sobriety tests that an officer will conduct if he or she suspects that a motorist is under the influence. I have conducted three of these tests myself and found that it is a good thing to conduct these field test because‚ it gives the officer the ability to know the status of an individual’s ability to operate a vehicle and it also gives the officer a sense of how to deal with the motorist. For example‚ a police officer might find them self in a situation where they

commercial Maglev was opened in 1984 in Birmingham‚ England‚ covering some 600 meters between its airport and rail hub How it works • A maglev train floats about 10mm above the guideway on a magnetic field. • It is propelled by the guideway itself rather than an onboard engine by changing magnetic fields • Once the train is pulled into the next section the magnetism switches so that the train is pulled on again. • The Electro-magnets run the length of the guideway. How it works • The train cars use
