Abstract
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.
