The paper describes analytical approach solving the problem of dynamic analysis of twodimensional fields of vibrational displacements and rotations caused by forces acting on stator of AC machine. Final set of three differential equations converted into algebraic ones is given and it is confronted with numerical solutions obtained by finite element method.
