MAGNETIC MODULE FOR AN ELECTRIC MACHINE EXCITED BY A PERMANENT MAGNET

摘要

An electric machine excited by a permanent magnet, particularly a larger generator of a wind power station, is to be produced and assembled easily. According to the invention, magnetic modules (1) are provided. A rotor can be equipped, for example, with said magnetic modules. Each magnet module (1) comprises a carrier plate (4) for fastening to the rotor, at least one permanent magnet (3), which is disposed on the carrier plate (4), and a covering device (2). The at least one permanent magnet (3) is fastened to the carrier plate (4) such that it is located between the carrier plate (4) and the covering device (2). Advantageously, these magnetic modules (1) can be easily installed or replaced in the gap between the rotor and stator.
