Abstract :
This paper investigates the thrust forces of two novel permanent magnet transverse flux linear oscillating actuators (TFLOAs), one with moving magnet and the other moving both magnet and iron core, for pump and compressor drives. Different from the conventional linear actuators, the lamination construction of the TFLOAs is similar to that of a normal rotating motor, which is easy to stack. Based on a simple magnetic circuit model taking into account the interpole leakage flux, the thrust forces are deduced analytically. The predicted results are verified by the finite element analyses and validated by experiments. It is shown that the thrust force performances of both TFLOAs are similar, whereas the former has a lower thrust force density and higher resonant frequency.
