Rotor Speed Control of a Direct-Driven Permanent Magnet
Due to the intermittent nature of wind, the wind power output tends to be inconsistent, and hence maximum power point tracking (MPPT) is usually employed to optimize the power extracted from the wind resource at a wide range of wind speeds. This paper deals with the rotor speed control of a 2 MW direct-driven permanent magnet synchronous generator (PMSG) to achieve MPPT.

External Rotor Motors Fisher & Paykel Technologies
External rotor motors allow for a more axially compact design while offering the same performance characteristics as internal rotor motors. The thinner magnets use a smaller amount of magnetic material, making external rotor motors lighter in weight. The compact nature of external rotor motors can be a significant space-saving solution that works well for many applications.
