- Abstract
Reducing the weight of the materials used in the creation of electromagnetic devices and decreasing the overall size of the latter greatly increases the attractiveness of low-voltage switchgear such as relays, contactors, and motor starters. These goals can be achieved by forced control of their driving electromagnets and the development of a technique for minimizing weight and size. In this paper, these problems are solved for a shell-type plunger constant-voltage electromagnet used as a drive. For the preferred region of the factor space of the source design data, a computational experiment was performed in accordance with a second-order orthogonal central composite design for eight variables. The polynomial models were developed for an optimal relative proportionality of a working air gap, the winding height and thickness, the outer collar height in fractions of an optimal core diameter, and the stop height in winding fractions. Examples of the calculation of the optimal electromagnet size minimizing its overall volumetric dimensions are given.
