Abstrakty
The minimizing of total losses in a squirrel-cage induction motor can be achieve through voltage control. For every load exist an optimal value of voltage which reduces the losses. This optimal voltage can be determined by using an analytical method, which was worked out by author. The application of this method requires knowledge of core and mechanical losses, magnetization characteristic, resistances and reactances of motor windings. The investigation of proposed method was made for a small motor with rated date: P{N} =1.1 kW and n(N) =1415 rev/min. For this motor two steering characteristics U(opt) =f(Ts) were prepared; first through laboratory measurements and second using the analytical method. The both characteristics made for five selected frequencies 50,40,30,20,10 Hz are compared in Fig.1. The comparison shows the close agreement of both characteristics. These results proved usefulness of the proposed analytical method for calculation of optimal voltage.
