The analysis of linear motor magnetic properties and application of several linear motor models at work have been performed in consideration of its constructional speciality. The mathematical model of linear motor have been composed on programme QuickField. Varying parameters of linear motor (elements position, materials proportion of motors elements, thickness of secondary element, its position on air gap symmetry) have been maked magnetic properties, specific for several model of linear motor. The teoretical part represent generalized review of linear motors and description of its characteristics. The features of linear motors have been analysed here. The investigation part involving the creation of several linear motor models and analysis of magnetic properties on programme QuickField. This discribing geometric models creation, its parameters setting and making results for several models of linear motors. The programme displaying results in grafic, color map, vector and tables shapes. The results have been analysed and summarized. Finally the conclusions of investigation of linear motor have been formulated: efficiency, operating conditions, application of linear motors are conditioned by constructional speciality of several linear motor. The results of investigation can be used for rational and optimal realization of linear motors in various technological systems.

Analysis of electromagnetic stepper motor at work have been performed. Types of stepper motors and its characteristics have been described generally. The programmes of modelling have been searching using internet and analysed. The programme QuickField 5.2 Studen‘s edition is in consort to demands and requests. Using QuickField 5.2 Student‘s edition the model of electromagnetic motor have been created and experimentations have been performed. Varying displacement of motor magnetic part the distribution of magnetic flux density and magnetic field lines have been analysed. The experimentations involving change of motors mechanical characteristics too (varying air gap between magnetic circuit and secondary part). Teoretical characteristics of distribution of magnetic field energy density, strenth and magnetic flux have been maked and compared. The conclusions and theoretical results specifying operating principle facility of electromagnetic motor. Characteristics of distribution of magnetic field and energy can be used for rating of influence to operation of motor.
