Energy Saving Control of Series Excitation Motor

Losses optimization in transients with series excitation motor (SEM) control just by control, at that controlled value is input voltage of SEM, is considered in this paper. Algorithm of optimal control of SEM, that allows to define SEM control optimality in relation of production by method of dynamic programming with eliminations of current and voltage, is suggested. It is defined, that optimal control in SEM transients in relation of production is same as optimal control with energy losses minimu

Energy efficiency improvement of medical electric tools and devices

With the ever-increasing volume of applications of various kinds of electric drives in all spheres of human activity, the issues in improving the efficiency of the electromechanical converters of electric energy, one of the most important components of the electric drive (ED), are becoming increasingly important. Such issues include reducing their weight and size, improving the functional characteristics of these devices to increase their operational life and reducing the cost of manufacture. Taking full advantage of these opportunities relates to the AC and DC single-phase commutator motor (SCM), which is widely used in regulated and high-speed motor drives in medical electric hand tools. The SCM is used in machinery where the load torque has a hyperbolic dependence on the rotational speed and the need to work with a large motor overload due to the “soft” mechanical characteristics of such motors
