Abstract

The structure of the motor essentially includes a ferromagnetic bar moving inside a fixed solenoid. The solenoid itself is a part of a series-resonant RLC circuit. Changes of the solenoid inductance and magnetic force, induced by changes of position of the ferromagnetic bar. are the variables of main interest. The performance of the motor can be assessed with an acceptable degree of accuracy thanks to the numerical computation of the magnetic field. A 'finite elements" simulation has been carried on and the results were compared between 3-D and 2-D mode. Calculated results are eventually compared to actual measurement data. 1 Introduction Whenever the required mechanical power is lower than 10 W, as for instance the driving shuttle of a weaving loom or the pneumatic hammer, a linear reluctance self-oscillating mono
