This paper presents some novel force ripple reducing techniques for tubular permanentmagnet linear machines (TPMLMs) with the square-shaped cross section. These methods are very straightforward, so their implementation in TPMLMs with the square cross section is easy. An analytical form of machine parameters such as the thrust force is obtained by solving the analytical field. A modular configuration for permanent-magnet pole is used to reduce teeth cogging force. Furthermore, the manufacturing cost of TPMLMs can be reduced by using modular pole permanent-magnet. In this method, the width of permanent-magnets (PMs) is calculated by using Fourier analysis and a sensitivity analysis has been conducted to identify the robustness of this technique. Additional stator side methods are used to decrease the end face cogging force. Moreover, the stator teeth shifting method is proposed to reduce the electromagnetic force ripples. Also, the produced electromagnetic force of the machine is increased by using a delay in the power supply. 3 -D non-linear finite-element analyses and experimental tests are performed to investigate the effectiveness and performance of proposed techniques.
