Permanent-magnet synchronous machine for slowly rotating wind power plant, has counterpart provided as fastening part at magnet wheel, which is formed from two disk-shaped units and aligned bars that run axially perpendicular

摘要

The machine (1) has a stator (2) with a coil system, and pole segments (22) arranged on a magnet wheel (7), where the pole segments exhibit permanent magnets (12). The pole segments are provided within an area of pole shoes, where each shoe is provided with recesses. A counterpart is provided into the recesses as a fastening part at the magnet wheel. The magnet wheel is formed from two concentric, disk-shaped units (23) and pairs of aligned bars (8) that run axially perpendicular. The permanent magnets are secured at an upper surface of a pole iron by tape binding.
