Abstract

The PCB sliding coil motor without iron core has the advantage of no teeth interlocking, no positioning force, lower thrust density, no attraction between the stator and the rotor, which leads to a smoother thrust generation, reduced thrust fluctuation, and correspondingly lower vibration and noise. These are its significant advantages, but it also has the disadvantage of complex manufacturing process, complicated bone structure design and winding fixing, and difficulty in installation in applications with limited installation space. In view of this problem, this paper designs a PCB sliding coil motor with a thrust of 6.4N. The motor uses a PCB board to replace the epoxy resin used to fix the winding, which can reduce the size of the motor. The PCB winding has the advantages of good manufacturing process, high precision, low cost, and easier mass production. This paper conducts research on the electromagnetic design of the PCB sliding permanent magnet synchronous linear motor and carries out design work on the PCB sliding permanent magnet synchronous linear motor. Initially, the structure and operating principles of the linear motor are elucidated, followed by the design of the motor in accordance with specified requirements. Upon determining the motor's dimensions, a model is constructed and simulated using ANSYS Maxwell software. The simulation outcomes are then analyzed to validate the accuracy of the design.
