Electromagnetic design analysis of single layered linear switching machine with fixed DC excitation for rail brake systems

A number of new approaches is done recently in railway braking system by the way of minimizing energy loss. A prolific method of braking is the use electromagnetic brakes replacing the conventional mechanical and permanent magnet infrastructure is presented in this work. The electromagnetic design of a linear switched reluctance machine with controlled DC excitation for the purpose of braking is introduced. It is found that the DC field excitation coil produce the same effect as that of the permanent magnet structure with an improvement of 43.3% of thrust to volume ratio, a key development in this field of study.
