Article is devoted to development of mathematical model of the artificial heart constructed on the basis of the mechatronic unit of bilateral action. The mathematical model represents system of the equations of movement of the mechatronic unit working in a reversive mode and consisting of the brushless motor and the planetary roller screw mechanism. The key varied parameters are time of a cycle, blood pressure, motor and mechanism parameters, frequency of blood pulsations, emission volume. For the solution of the differential equations the program MATLAB complex was used. As basic data time of a blood cycle, a blood pressure, motor and mechanism parameters, frequency of blood pulsations, emission volume were used. Theoretical values of moving of the mechanism, speed of a membrane, an expense and instant capacity are received. Result of the analysis of mathematical model are power characteristics for the motor of the mechatronic unit. It allowed to define concrete brand and an motor standard size for a drive of artificial heart.
