Abstract
An electric field-reducing insulating layer is described for an inductive coil. In some examples, a first coil having at least one first winding is arranged for being driven at a first voltage. A solid insulating layer is adjacent the first coil and has a first surface facing the first coil. The first surface of the solid insulating layer has a first groove between the first winding and the insulating layer, having a width that is smaller than a diameter of the electrical wire. The first groove forms a pocket between the first winding and the solid insulating layer.
Claims24
A device, comprising:
- a first layer including a first coil having at least one first winding of a first electrical wire, the first coil configured to be driven at a first voltage, and
- a solid insulating layer adjacent the first layer, the solid insulating layer having a first surface facing the first coil and a second surface opposite the first surface,
- wherein the first surface comprises a first groove between the at least one first winding and the solid insulating layer, the first groove having a width smaller than a diameter of the first electrical wire, wherein the first groove forms a pocket between the at least one first winding and the solid insulating layer.
