【 摘 要 】

The design of the linear electromagnetic motor providing the increase of inductance modulation depth and concentration of magnetic flux in the operating air gaps is considered. The analytical method for calculation of static characteristics of the linear electromagnetic motor with several operating air gaps connected in series into the magnetic circuit is obtained. Calculations are made using the method of the magnetic circuit theory. Based on the Ampere's circuital law, the expressions of the magnetic flux and traction force are obtained. The comparison of calculating and experimental results is presented.
