Transient Characteristic Evaluation Method for Linear Motors

Abstract

In applications involving high-speed drive or short-range movement, the effective performance of linear motors is assessed by evaluating transient states. However, there are fewer reported cases of performance evaluation methods for transient states, as compared to those for steady states. This study investigates a transient characteristic evaluation method for linear motors. We propose a method to quantify energy during acceleration and deceleration using the integral of input and output waveforms. The performance at the transient state is calculated by using control simulation and the FEM analysis. The evaluation results of the proposed method are reported. The validity of this method is verified through comparison between experimental and simulation results of energy loss.
