Konstrukcja i modelowanie bezżłobkowego silnika tubowego z magnesami trwałymi

The paper presents the construction of the coreless permanent magnet tubular linear motor. Detailed design and the manufacture technology of the complete physical model are described. The parametric field model of the machine is showed as well as the results of the calculation of the back-EMF and the force affecting the mover (moving part). The machine with the constant speed of the mover is analyzed in three cases: without power supply, with direct current source and sinewave voltage source. Simulation results are compared with measurements taken from the physical model. Additionally, an influence of a stator container tube length on cogging force characteristics was investigated, leading to a calculation of an optimal length, where the cogging force is minimal.
