  The object of the study is Unbalanced Magnetic Pull (UMP) which arises in electric motors and generators and must be taken into account in rotor dynamics tasks. Review of existing methods of UMP determination is presented, its nonlinear nature is noted. The algorithm to solve the task of rotor dynamics behavior with UMP in nonlinear transient analysis is created. The hydraulic turbine generator model is taken as an example. Magnetic forces influence on hydraulic turbine generator dynamic characteristics is shown.
