The purpose and the task of practical work and course design.

The purpose of practical work and course design is to consolidate and practically learn specific tasks of calculation and design of electric drive by given technical conditions. For providing of given task students of specialty 8.092203 during practical works and in a process of course design successively realize four tasks which are given in these methodical instructions by the next chapters:

• mechanics of electric drive, calculation of electromechanical and mechanical characteristics;

• calculation of load diagram and choosing of drive capacity by heating;

• calculation and construction of static characteristics of thyristor drive (ТП - Д);

• calculation of transient processes in double-weight spring electromechanical system of electric drive.
