(Engineering), Professor, e-mail: nv.nstu@ngs.ru Novosibirsk State Technical University, 20, Prospekt K. Marksa, Novosibirsk, 630073, Russian Federation Abstract The work is devoted to the study of linear electromagnetic motor with an active gear area for the electric drive of vibrokompressor. The presence of the active gear area provides high amplitude values of the static traction characteristics without mechanical fixation of the end position of the rotor and the use of complex control circuits. The correcting k1 coefficient considering a corner of disclosure and number of couples of poles of the stator of the engine is offered. Research on change of statement of the solution of a task in numerical experiment taking into account the correcting coefficient is executed. It was established that in the calculation of the magnetic conductivity of air gaps of the gear area, taking into account the maximum relative error of k1 values obtained does not exceed 14%. The results can be used in the design of the electromagnetic linear motor with an active gear area for the electric drive of vibrocompressor.
