|Citation:||Ooi, Boon-Teck, Low, Teck-Seng (1990-06). Electromechanical spring stiffness from the small perturbation linearized equations of generalized machine theory. IEEE Transactions on Energy Conversion 5 (2) : 374-379. ScholarBank@NUS Repository. https://doi.org/10.1109/60.107235|
|Abstract:||The authors derive the static electromechanical spring stiffness coefficient of the class of balanced polyphase electric machines which are amenable to the generalized machine reference-frame transformation. The stiffness coefficient derived from the torque equation of the original unprimed frame expressed in the linearized small-perturbation form is given. The spring stiffness, which is physically present but suppressed in the reference-frame transformation, is then modeled and can be used effectively for transient analysis and the analysis of the dynamics of motion control systems. A procedure for the calculation of the stiffness coefficient is described and the electromechanical spring stiffness coefficients of synchronous machines and the induction machine are derived.|
