摘要

After review of the linear two-dimensional theory of solid rotor induction machines, the so-called composite rotor induction motor is analyzed. The rotor consists of layers of various combinations of magnetic and conducting materials. It is shown that by right selection of layer combinations a nearly ideal constant torque motor can be designed. For the consideration of end effects of a short rotor-motor, a three-dimensional linear treatment is developed. The basic partial differential equations are established and boundary conditions described. After a general solution is found, the boundary conditions satisfied in the least square sense yield the necessary constant. The solution shows clearly the end effects influence. Long and short motors are compared. In the two-dimensional nonlinear numerical solution of the solid rotor induction motor the B-H characteristic is represented as a piece-wise linear curve. The solution is obtained by a successive line relaxation technique of the vector potentials and by underrelaxation of the reluctivities. The results show the influence of saturation. (Author)
