Embodiment Construction
[0036] figure 1 A pole lock device 1 according to one embodiment of the invention is shown. The pole lock device 1 comprises a spring-loaded element 10 arranged below the housing frame 11 such that a spring portion 100 of the spring-loaded element 10 protrudes through a hole 110 of the housing frame 11; an anchoring element 12 protrudes through an anchoring element opening 112; The magnet side portion 101 is exposed at the other end of the housing frame 11 . The housing frame 11 also includes a retainer 111 extending around the spring portion 100 of the spring loaded element 10 for preventing fragments of the spring portion 100 from falling into the air gap if the spring portion 100 of the spring loaded element 10 breaks or breaks. In order to prevent inadvertent unlocking of the pole lock device 1 from its rotor slot, the housing frame 11 comprises anchoring shields 13 extending along the sides of the housing frame 11 outside the anchoring elements 12 . In order to allow th...

The invention relates to a pole lock device (1) for limiting the axial movement of a magnetic pole (3) held in a field slot (20) of a field structure (2) of an electric machine, comprising a A spring-loaded element (10) exerting an axial force (F) on the pole in the field slot; realized as a housing frame (11) holding the spring-loaded element in the field slot; and realized as an anchor for the pole lock Anchor element (12) fixed in the magnetic groove. The invention also describes a field structure of an electrical machine comprising at least one field slot realized to accommodate a magnetic pole, wherein the field slot comprises engaging means (21) shaped to accommodate an anchoring element of a pole lock device according to the invention . The invention also describes an electric machine comprising such a field structure, a pole arranged in a field slot of the field structure, and a pole lock arranged such that the anchoring element of the pole lock engages with the engagement means of the field slot.
Description
technical field [0001] The invention relates to a pole lock device, a magnetic field structure, and a motor. Background technique [0002] Permanent magnets are commonly used in large electrical machines such as electric motors or generators. Such a motor consists of two basic components, a magnetic field, which generates flux, and an armature, which generates electromotive force and flows current through the magnetic field. The armature typically includes conductive coils wound around a stator, while the field typically includes magnets disposed on a rotor. The rotor can surround the stator, or vice versa, with the magnets and coils facing each other through a narrow air gap. Established methods of loading or mounting permanent magnets to the field (or field structure) of an electric machine include various steps such as housing the individual permanent magnet poles and bonding the permanent magnet poles to the field (usually the rotor ), wrap the entire setup in fibergl...
