Characteristic analysis of transverse flux type linear oscillating actuator according to slot number

Abstract

A transverse flux linear oscillatory actuator (TFLOA) for a compressor is proposed, which features a unique configuration consist of dual stator cores, single-phase winding coil and permanent magnet (PM) mover. It not only offers low manufacturing cost and good magnetic force density, but also provides high efficiency for its transverse flux flow. This paper deals with the design and electro-magnetic analysis of TFLOA according to a number of slots. For the same comparison, the use amount of the moving magnet, the outer diameter of the stator core, the moving stroke, and the frequency are selected equally. Finally, we compared the electro-magnetic characteristics such as no-load analysis, electromagnetic loss analysis, electromagnetic output and efficiency of each TFLOA and proposed the optimal TFLOA.
