Abstract:

The calculation of the performance characteristic of high-speed, aerospace, solid rotor induction motors is attempted. The mathematical model is three-dimensional, so that changes in the torque-speed characteristic caused by the losses in the end region of the solid rotor are considered. The iterative relaxation method described calculates the electromagnetic quantities in the solid rotor as function of three space variables and the time. The appropriate partial differential equations, their transformation to partial difference equations, and the boundary condition are developed. The iteration procedure is explained, flow diagrams and computer programs are included. The whole scheme is then applied to calculate the torque in a 5 h.p., six-pole, 3200 cps, 145 volts, wye-connected induction motor. Author
