摘要：
The methods of improving the thrust force and the influence of its fluctuation on the operation stability and positioning accuracy are investigated based on the primary studied back-to-back Ω stator transverse flux permanent magnet linear machine (BBΩ-TFPMLM). First, several key parameters affecting the positioning force of the motor are excavated and the influencing mechanism is analyzed. A method of employing the rotational torque to measure the linear force is proposed. Secondly, the length of the air gap, the thickness of the permanent magnet, the width of the mover tooth and the distance of the staggered pole are simulated and optimized based on the Taguchi method and the three-dimensional finite element analysis method (3D-FEM). The optimal structural parameters, and the motor positioning force, the thrust, and the back EMF curve are obtained. Finally, a prototype experimental platform is built and some experiments are conducted to test the optimized parameters. The simulation and experimental results both show that the peak-to-peak value of the positioning force of the optimized motor is reduced by 38.3%, the thrust amplitude is increased by 21.1%, and the back EMF amplitude is increased by 5.2%, which verifies the feasibility of the thrust ripple reduction method. ©2023 Chin.Soc.for Elec.Eng.
