Finally, a sensorless control is developed for the PMG wind turbines to continuously generate the maximum electrical power without using any wind speed or rotor position sensors. The validity of the proposed estimation and control algorithms are shown by simulation studies on a 3-kW PMG wind turbine and are further demonstrated by
The large majority of existing wind turbines from 5 to 500 kW capacity are using gearboxes between rotor and generator in order to achieve 750 -1500 RPM on the generator shaft. However, there are some disadvantages of using gearbox: • reliability of the wind turbine is reduced due to gear transmission between wind rotor and generator;

We challenged the wind industry by making permanent magnet generators (PMGs) and full-power converters the preferred technology for wind turbines. Now, nearly all new large-power wind turbine designs have permanent magnet and full-power converter drive trains. Today, we optimize and tailor-make medium-speed PMGs especially for selected OEMS.
Description. Synchronous generators are the majority source of commercial electrical energy. They are commonly used to convert the mechanical power output of steam turbines, gas turbines, reciprocating engines, and hydro turbines into electrical power for the grid. Some designs of wind turbines also use this generator type.. In the majority of
Alternative technology is needed in designing the generator for wind turbine application to reduce the size, weight, and cost of the generator. In large wind
This paper proposes a wind speed and rotor position sensorless control for wind turbines directly driving permanent magnetic generators (PMGs). A sliding-mode observer is designed to estimate the rotor position of the PMG by using the measured stator currents and the commanded stator voltages obtained from the control

When using our permanent magnet generator for wind turbines, power density is increased using inverter technology, where the traditional excitation winding systems are replaced and the stator is central with an external rotor. This maximises the potential of the magnets used. Zanardi PMG
The current commercial PMG wind turbine on market is surveyed. The design of a 5 MW axial flux permanent magnet (AFPM) generator for large wind turbines is discussed and presented in detail.
Wind turbine blades can be conveniently assembled in front of the rotor cylinder, thus directly coupling the wind turbine with PMG. 2. For the same outer diameter of PMG, the outer-rotor design provides more space for mounting a larger number of magnetic poles. 3. Permanent magnet can have the simplest flat shape.
