Abstract
Official abstract text for this publication.
There is provided a pole-piece for a torque motor, the pole-piece comprising a first section formed separate from a second section, wherein the first section and the second section are configured to abut each other to form one or more lines of abutment on an outer surface thereof, and each line of abutment follows an S- or Z-shape when the first section abuts the second section.
First claim
Opening claim text (preview).
The invention claimed is: 1. A method of manufacturing a pole-piece for a torque motor, the method comprising: providing a single-piece of magnetic material; cutting the single-piece of magnetic material along one or more lines in an outer surface thereof to form a first section separate from a second section, wherein the lines follow an S- or Z-shape; calculating a distance (A) that the second section will need to move to contact the first section after the cutting step; and positioning features on the single-piece of magnetic material, prior to cutting, so that they are not aligned before the cutting, and then align after the cutting and upon moving the first section into contact with the second section. 2. A method as claimed in claim 1 , wherein the distance (A) corresponds to a gap (G) between the first section and the second section, wherein the gap (G) is formed by removing material during the cutting step. 3. A method as claimed in claim 1 , wherein the features are corresponding features that are located on both the first section and the second section.
