Abstract

The invention discloses a portable permanent-magnet direct-drive double-stator wind power generator, which comprises an end cover assembly, an inner stator assembly, an outer stator assembly, a bolt combination piece, a stator welding part, a rotary shaft and a hollow cup rotor assembly, wherein the inner stator assembly, the outer stator assembly, the bolt combination piece, the rotary shaft and the hollow cup rotor assembly are respectively arranged on the end cover assembly to form a motor; the end cover assembly comprises an end cover which is provided with an inner spigot and an outer spigot and a bearing chamber which is formed on the end cover and is in a cup shape; a first bearing and a second bearing are elastically fixed in the bearing chamber in axial direction; the inner stator assembly is in clearance fit with the inner spigot on the end cover and then is locked on the end cover in the axial direction through the bolt combination piece; the outer stator assembly is fixed in the outer spigot on the end cover in an interference fit mode; and central lines of teeth which correspond to the stator assemblies are coincided. The portable permanent-magnet direct-drive double-stator wind power generator has the advantages that all parts can be accurately positioned by using the hollow cup end cover with double spigots, the overall material is fully utilized, and the motor is quite light.

Description

technical field [0001] The invention relates to an off-grid wind power generator equipment, in particular to a portable permanent magnet direct drive double-stator wind power generator. Background technique [0002] As one of the pillars of modern life, the supply of electric energy is becoming increasingly urgent; and green consumption is the main measure to protect the earth, so the development of wind energy occupies a prominent position in the existing new energy pattern. China is rich in wind energy resources, and the available wind energy is about 2.53 billion MW. The current mainstream is large and medium-sized networked wind power equipment undertaken and developed by large energy groups, and the threshold is relatively high; for remote mountainous areas, pastoral areas, islands and other places, solving their electricity demand is an important way to improve people's livelihood measure. Limited to geographical conditions, what these places need is a miniature off-...
