Abstract

The structure of a cylinder linear motor is presented. And the axial symmetric vortex analytical equation

which fits for its structure characters

is established and the solution is given. This axial symmetric FEM model is set up with the variation theory. Simulation results reveal that these two methods are consistent

and the analytical model is effective and efficient. Moreover

based on the analysis

a cylinder linear motor model was manufactured with appropriate structure parameters

and the change of the start pushing force measured. The test results and the calculations have the same tendency and approximate value. It proves that the analytical model meets the calculation of the cylinder linear motor. Therefore

it verifies the reliability of this method. Furthermore

the above research reveals that the cylinder linear motor meets the demand of driving the mobile sculpture shadily. The main structure parameters

such as the air gap

the thickness of the secondary end and those may affect the performances of the linear motor were also investigated. It is found that when the air gap increases

the pushing force decreases. When the thickness of the secondary is 10 mm

the pushing force reaches its maximal value of 198.5 N.
