The invention describes a pole-locking device (1) for limiting the axial motion of a magnet pole (3) held in a field slot (20) of a field structure (2) of an electrical machine, which pole-locking device (1) comprises a spring-loaded element (10) realised to exert a (axial) force (F) on the magnet pole (3) held in the field slot (2); a housing frame (11) realised to retain the spring-loaded element (10) in the field slot (2); and an anchor element (12) realised to anchor the pole-locking device (1) in the field slot (2). The invention further describes a field structure (2) of an electrical machine, which field structure (2) comprises at least one field slot (20) realised to accommodate a magnet pole (3), wherein a field slot (20) comprises an engaging means (21) shaped to accommodate an anchor element (12) of a pole-locking device (1) according to the invention. The invention also describes an electrical machine comprising such a field structure (2), a magnet pole (3) arranged in a field slot (20) of the field structure (2), and a pole-locking device (1) arranged such that the anchor element (12) of the pole-locking device (1) engages with the engaging means (21) of the field slot (2). |
