Abstract
In the design of reciprocating electromagnetic drives, the correctly selected number of turns of windings defines the required supply voltage. Using simplified mathematical models, the correlation is theoretically determined between the design factors of an electromagnetic impact drive (number of loops and wire section of winding) and the in-process dynamics (currents, coil voltage, impact energy and frequency). The analytical expressions to correlate the listed parameters are derived. Their variability is analyzed, and the recommendations to select the number of loops of windings are made. The calculation-based findings are confirmed in dynamic testing of model electromagnetic impact drives.
