Abstract

The invention discloses a power generator and a wind generating set. The power generator according to the embodiment of the present invention comprises: a stator; a rotor arranged on the peripheral side of the stator in a sleeving mode, and provided with an opening end and a supporting end opposite to each other in the axial direction; and an air gap maintaining assembly provided with a first connecting end and a second connecting end, wherein the first connecting end is connected with an external driving piece, the second connecting end is connected with the opening end of the rotor, and the air gap maintaining assembly acts on the opening end and is used for maintaining the consistency of an air gap between the stator and the rotor in the direction from the opening end to the supporting end. According to the wind generating set provided by the embodiment of the invention, the problem of non-uniform air gaps of the generator can be solved.

Description

technical field [0001] The invention relates to the field of power generation equipment, in particular to a generator and a wind power generator set. Background technique [0002] A wind turbine is a device for converting wind energy into electrical energy. The main component used for energy conversion is a generator. The generator usually includes a rotor and a stator. The rotor and the stator are arranged opposite to each other with a motor air gap between them. When the generator is applied to a wind power generating set, its rotor is connected to the hub of the impeller, and the impeller drives the rotor to rotate under the action of the wind, so that the rotor and the stator cut the magnetic force line, thereby generating magnetic induction current and generating electricity. [0003] As the power of the wind turbine increases, the weight of the impeller and the wind load also increase accordingly. The rotor deforms more and more under the action of gravity and wind loa...
