This paper presents an analytical approach to modeling the relationship between applied magnetomotive force and mechanical force produced for a non-laminated cylindrical magnetic actuator. The approach is based on dividing the actuator into elements according to the flux distribution inside the actuator, and finding the frequency-dependent reluctance of the flux paths of each element. An analytic model and its half order simplification are derived, both of which are explicitly dependent on actuator material and geometric properties. Performance predictions from both analytic models are compared with finite element analysis, demonstrating the accuracy of the models.
