Abstract: Stellarator magnetic configurations with different combinations of plane circular tilted current coils were studied. Two types of coil combination used for forming of the magnetic configurations: cohesion tilted coils (Villarso coils) and uncoupling tilted coils. As torsatron type, so stellarator type systems with multipolarities l = 2, l = 4 and their combinations were studied. For the first time magnetic configurations with good confinement properties created by system of uncoupling coils stellarator type current combinations were obtained. Splitting of l = 2 coil system allows to obtain l = 4 harmonic, that goes to improvement of confinement properties of the configuration. Variation of value corrective field allowed to obtain quasisymmetric properties of the stellarator configuration.
