Design of DC electromagnet
Mayer, Aleš ; Bušov, Bohuslav (referee) ; Šimek, David (advisor)
This bachelor thesis deals with electromagnets and measurements on them. There is described the history of discovery of electromagnets, the principle of operation, their construction, and classification according to various criteria. More detailed descriptions of individual basic types are presented. The method of deriving the tensile force calculation is explained for DC as well as for AC electromagnets. There is a detailed description of the design process of a core DC electromagnet, which is then simulated in the FEMM program, and a 3D model with technical documentation is created in the Inventor program. The part also deals with measurement on electromagnets. More precisely, it is a measurement of static and dynamic tensile characteristics, measurement of electromagnets temperature rise. In the next part, transient phenomena and their measurements are explained, namely inrush current and switching overvoltage.
