AB - <p>The rotating magnetic field which is created in a vide space is investigated. It can be used for any technological applications .The total magnetic field created by three exciting coils with angles between axes equal to 120o is analyzed. The exciting coils are connected to three-phase current source. The amplitudes of particular phases currents are not equal. The expressions are obtained for computation of magnetic flux density vector length and position in the plane, perpendicular to rotation axis in any moment. The values of magnetic flux density length and rotating velocity vary periodically in the time. The variation limits depend on the unbalance coefficients. The rotation will be non-uniform, but the mean value of rotation speed along the any half of period will be equal to rotation speed in the balance case. Ill. 4, bibl. 3.
