Dynamics modeling and load analysis of linear motor for LEHA system

Linear oscillating motor provides short-stroke reciprocate motion with high efficiency and long lifespan, receiving much attention, especially in aerospace applications. LEHA is a novel flight actuation system, in which linear oscillating motor plays an important role. Thus, high output performance of LEHA relies on detailed researches into dynamics of linear motor. In this study, dynamics model is set up first for linear oscillating motor and then analyzed in frequency domain. The influence of electrical and mechanical parameters on output performance is clarified, which contributes to motor design and optimization for LEHA system.
