“…Furthermore, the voltage distribution in the foil coil is shown in Figure 2. Semi-analytical modeling of the linear actuator configuration, as performed in [11], has limited accuracy near corners and edges of conducting regions. Therefore, the linear actuator configuration with the different field control methods field is modeled with 2-D boundary element and finite element method using Integrateds Electro [12].…”

This paper describes multiple electric field control methods for foil coils in high-voltage coreless linear actuators and their sensitivity to misalignment. The investigated field control methods consist of resistive, refractive, capacitive and geometrical solutions for mitigating electric stress at edges and corners of foil coils. These field control methods are evaluated using 2-D boundary element and finite element methods. A comparison is presented between the field control methods and their ability to mitigate electric stress in coreless linear actuators. Furthermore, the sensitivity to misalignment of the field control methods is investigated.
