4 Frequently Asked Questions about “Wind power semi-direct drive generator - RRR Renewable Projects (SA)”
What is direct drive permanent magnet synchronous wind turbine?
With the continuous progress of power electronic technology and computer control technology, large-scale wind turbine can use the technology of direct driven permanent magnet wind turbines. Direct drive permanent magnet synchronous wind turbine is characterized by low speed and high torque requirements , , .
What is direct drive wind turbine?
Direct drive wind turbine adopts multi-pole structure, which can achieve the direct coupling between the wind turbine and generator, so the gearbox can be omitted, , .
Which synchronous wind turbine design scheme has the least use of permanent magnets?
The electromagnetic design scheme of 50 poles and 180 slots has the least use of permanent magnets and the lowest cost. It can be selected as the best scheme for the production of the 1.5 MW semi-direct drive permanent magnet synchronous wind turbine. Table 2.
Does a permanent magnet synchronous wind turbine use ferromagnetic materials?
Although the no-load flux leakage coefficient of permanent magnet synchronous wind turbine increases with the increase of motor poles resulting in the decrease of air-gap flux density distribution, the increase of motor frequency will reduce the use of the permanent magnet and ferromagnetic materials.
