Abstract: This paper deals with the improvement of starting characteristic for Moving Magnet type Linear Oscillatory Actuator (MM-LOA) using a spring damper. MM-LOA is applied to variable loads such as vacuum pumps and compressors. However, it has the characteristic of over-displacement in starting state because of the low inertia of mover. To improve the starting characteristic, a spring damper has been adopted in a mechanical system. The design parameters have been computed by 2-D Finite Element Analysis (2-D FEA). In addition, dynamic characteristic analysis has been performed by time differential method. The propriety of improved starting characteristic is verified by a comparison of analyzed results with those of experiments.
