Analysis Of Torque-Speed Curves Of Wound Secondary Couplings In The Nonlinear Region Of The Magnetization Curve

This paper presents an analytical treatment to compute the torque-speed curve of a dc excited electromagnetic coupling considering magnetic saturation. The complete nonlinear magnetization curve is mathematically represented and the maximum torque is accurately predicted. The above approach being a generalized one can be applied to any electromagnetic apparatus working under saturation condition. The present coupling can also be used as a variable speed drive.
