Ring depth of coil clamping ring is the parameter to be calculated while designing, which decides its ability to withstand short-circuit force. In this study, parametric equations are proposed to calculate optimized depth of the rings for a given geometry and short-circuit force. Rings considered in this study have a slot which is a provision to accommodate the elliptical shape of (top yoke) core. Initially, finite element analysis of the rings available in literature is performed and verification-validation of finite element model is done. Then based on this finite element model, FEA of different rings considered in this study is carried out for short-circuit force. Results are verified using deflection equation for a straight beam closely resembling the loading and end conditions. Design of experiments is also performed to establish parametric equations using CAE tool. Using FEA, designed and optimized depths for few existing designs of coil clamping ring along with their corresponding maximum deflections are compared thereby verifying the proposed equations.
