Linear motor has a lot of applications, such as magnetic levitation train, electromagnetic weapons. It is a very important research significance. We established a three-dimensional model of linear motor to calculate the magnetic field lines and flux density distribution, and got the electromagnetic force too. We compared the results of simulation using COMSOL and experiment under different frequencies and found that they are consistent with each other, which verifies the accuracy of our calculation and meaning of used to guide the design.
