Semi-direct-drive axial composite dual-port permanent magnet synchronous wind-driven generator

Abstract

The invention discloses a semi-direct-drive axial composite double-port permanent magnet synchronous wind-driven generator, and belongs to the field of wind driven generators. According to the semi-direct-drive axial composite dual-port permanent magnet synchronous wind-driven generator, the wind-driven generator comprises a generator, a left coupling, a right coupling, a left speed increaser, a right speed increaser, a group of paddles, another group of paddles, and a yawing mechanism. The generator comprises a first casing, a second casing, a first stator iron core with a winding, a second stator iron core with a winding, a first rotor iron core, a second rotor iron core, a first permanent magnet, a second permanent magnet, a first rotating shaft and a second rotating shaft. The first stator iron core with the winding is fixed in an inner cavity of the first casing. The first stator iron core with the winding and the first permanent magnet induct each other to form a set of closed loop. The first rotating shaft is one input end of the wind driven generator. The second stator iron core with the winding is fixed in an inner cavity of the second casing. The second stator iron core with the winding and the second permanent magnet induct each other to form a set of closed loop. The second rotating shaft is the other input end of the wind driven generator.

Description

technical field [0001] The invention relates to a permanent magnet synchronous wind power generator, in particular to a semi-direct drive axial compound dual-port permanent magnet synchronous wind power generator. Background technique [0002] Energy and environmental issues have become the main issues faced by the sustainable development of global industry, which has attracted widespread attention from the society and seeks positive countermeasures. Wind energy is a renewable, non-polluting, green energy source that is inexhaustible and abundant. With the increasing social recognition of clean energy and the continuous advancement of technology, the world's wind power industry is developing rapidly, and the power of a single machine is continuously increasing. The volume of the generator is increased, and the length of the blade is lengthened, which not only causes a substantial increase in cost, but also causes difficulties in installation and transportation. The level is...
