In this paper, design and control of an asymmetric V-shaped segmented magnet arrangement for a linear permanent magnet (PM) synchronous motor is investigated. A single forcer single track structure is used in the investigation. Magnet arrangement for the track of the PM linear motor (PMLM) is also compared with an un-skewed magnet pole motor and the benefits of the proposed asymmetric V-shaped track are presented. Control of the machine at no-load and on-load are completed. The designed unconventional linear motor is manufactured and the test results are compared with the simulations. It is seen that there is good agreement between FEA and experimental results of the PMLSM. The benefits and the potentials of the V-shaped segmented magnet arrangement is also presented in the paper.
