In this report, the method of numerical modeling of the whole work cycle of electric motors of various types is proposed. This method considers the motion of mobile parts of electric motors, demagnetization of armature and stator steel of the motor as well as the eddy currents in the conductive parts of electric motors. During the modeling process this method makes it possible to calculate the following time-dependence characteristics: forces acting on armature, power consumption and available capacity, magnetic and heating losses, as well as velocity and displacement of armature. The possibilities of the proposed approach are demonstrated by the examples of calculating the work cycle of a linear electric motor and different types of asynchronous motors.
