Abstract
Efficient vibration and vibroimpact processes are common in industry. To implement these
processes linear electromagnetic impact machines are extensively used. These machines are based
on cylindrical power electromagnets which have relatively high power and energy efficiency. The
relevance of the research is dictated by the need to increase a specific impact of electromagnetic
power machines with a continuous operating mode, which is inextricably linked with the
development and design of efficient cooling systems. The function of these systems is to take all the
heat released by maintaining a maximum temperature of the coil impact unit at an acceptable level
determined by the magnet wire insulation class. The heating temperature of the electromagnetic
impact tool active elements using the software package ELCUT has been calculated. Diagrams of
temperature fields of the stationary heating mode of the impact unit active elements are shown.
