Modernization of an Electronic Control Module and Research of Heating Temperature of a Coils Wire of an Electromagnetic Hammer for Destruction of Boulders

Development and bench tests of a programmable logic controller “Simens Logo” based control system of an electromagnetic hammer for destruction of boulders

“…Turning on and off these electromagnetic actuators is carried out using the electronic control unit. The first versions of the electronic control unit are described in papers [12,13]. These papers show that the 155 series of digital logic circuits were used to generate control signals.…”
