Abstract
Various methods are described for minimizing the energy consumption of electric drive systems. The theoretical background for optimization of the efficiency level at stationary workpoints in shunt-type direct-current motors is briefly described. Measurements and calculations have shown that the degree of efficiency can be increased by 0-25%, dependent on the workpoint. The improvement continues with decreasing moment and number og revolutions. The theoretical basis for minimizing energy consumption at stationary workpoints with regard to induction machines controlled by frequency formers is also explained. Here the degree of efficiency can be improved up to 20%, dependent on the workpoint and improvement also continues in accordance with decreasing moment and number of revolutions. A method was developed for estimating the impedance of induction machines based on catalogued data. The method makes it possible to implement the open loop minimization of the energy consumption of the induction machine and can be generally used where knowledge of the relevant data is necessary. The theory for optimal regulation is described and used to determine the velocity profile for a direct-current motor. Calculations show that the degree efficiency can be improved by 12% by use of the optimal profile instead of the traditional trapeze profile. (AB)
