Active part for use in rotor or stator of e.g. generator, has active layer comprising connection area between recesses for arranging connection fiber such that fiber is guided into reinforced layer from sides of active layer

摘要

The part (1) has a magnetically active layer (2) i.e. permanent magnet, and a fiber-reinforced layer (4) arranged at the active layer. The active layer has a connection area (10) between recesses (7, 9) for arranging a connection fiber such that the connection fiber (5) is guided into the reinforced layer from sides (6, 8) of the active layer through the recesses. Fibers (3) i.e. carbon fibers, in the reinforced layers are guided in a direction along the active layer, where the connection fiber runs perpendicular to a direction of force produced during operation of an electrical machine. An independent claim is also included for a method for manufacturing an active part.
