Linear machines have been characterized as promising candidates for direct-drive applications such as railway traction. This is owing to the elimination of the rotary to linear mechanical interfaces which results in a very simple structure and reduced maintenance cost. This paper presents a driving system for partitioned stator linear wound field Vernier (PS-LWFV) machine. The armature and field windings of the machine are separately located in an upper stator and a lower one, respectively. The magnetic gearing effect and low-speed operation are the important features of this machine. In many applications, speed control is the essential requirement of the machine. This paper introduces a speed control system for this linear motor. The machine is simulated based on a mathematical model. To verify the model, the simulation results are compared to that of the finite element model. Matlab/Simulink software is employed for the machine and its converter simulation.
