Marksa, Novosibirsk, 630073, Russian Federation Abstract Linear electromagnetic motors are advantageous for use in the drive of press equipment for stamping, pressing, riveting, marking, etc. at an action frequency of 10 Hz. The principle of electromagnetic motor operation is based on the interaction of the winding magnetic field with ferromagnetic core. The equipment of this class converts electric energy into the kinetic energy of the operating unit rectilinear motion with no additional transmissions. Electromagnetic presses stand out as being much more advantageous than other equipment due to the absence of mechanical transmissions, precisely manufactured parts, a simple structure, and wide possibilities to improve reliability and increase their service life, a feasibility to control their force and frequency in a wide range of values, a possibility of automation, an easy control of their operation, and the absence of overloads. Analysis of the presses converting electric energy into useful mechanical work made it possible to significantly improve electromagnetic press force and energy parameters by providing new operating cycles to accumulate magnetic energy in the inductances under static and dynamic conditions by developing effective magnetic systems and designs of electromagnetic motors.
