Fiber composite plastic rotor for a transverse field-excited electric machine and a method for its production

摘要

The invention relates to a composite fiber-plastic rotor for a transverse-flow-excited electric machine and to a method for producing such a rotor. The object of the invention to find a new way to produce a fiber composite plastic rotor for electrical machines, which allows a modular design with custom-tailored recesses for reliable positioning and centrifugal force protection of the magnetic functional elements (3), is achieved according to the invention by a Rotor disc (2) of symmetrically arranged layers is constructed with at least one fiber-composite plastic layer as a support layer (21) to which connects at least one radial amplifier layer (22) with radially rectilinear fiber orientation adapted to radial webs (23) of the Inner circle (211) to the periphery of the carrier layer (21) reaching fiber spokes (221), and at least one positioning template (24) for defined positioning of the functional elements (3) and for fixing the ordered einlagerten fiber spokes (221) at least as long existing, until a flowable into the fiber layers (21; 22) introduced matrix material (25) is cured.
