THERMAL DESIGN OF THE IMPACT TOOL WITH AN ELECTROMAGNETIC DRIVE Neyman L.A. , Ph.D. (Engineering), Associate Professor, e-mail: neyman@ngs.ru Novosibirsk State Technical University, 20, Prospect K. Marksa, Novosibirsk, 630073, Russian Federation 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.
