Nettet28. des. 2024 · Faraday’s law of induction states that the induced EMF (i.e., electromotive force or voltage, denoted by the symbol E ) in a coil of wire is given by: E = −N \frac {∆ϕ} {∆t} E = −N ∆t∆ϕ. Where ϕ is the magnetic flux (as defined above), N is the number of turns in the coil of wire (so N = 1 for a simple loop of wire) and t is time. NettetA linear induction motor (L IM) is suitable for use in trains. The motor can be used in both wheel-suspended and contact-less types such as the Linear Metro and HSST trains in Japan. The LIM has end winding as well as asymmetrical winding. The end effect is a major problem in the LIM, and it makes the analysis, design, and control of motors ...
