Description
Technical field
The present invention relates to a kind of technology of motor field, specifically a kind of stator for wind-driven generator.
Background technique
Wind-driven generator is that one kind converts wind energy into mechanical work, and mechanical work drives rotor rotation, to export alternating current
Power equipment.Inventionbroadly, wind energy is also solar energy, it is possible to say that wind-driven generator is one kind using the sun as heat source, with
Atmosphere is the heat energy utilization generator of working media.The generating efficiency of traditional wind is low, and wind energy utilization is low, power generation effect
Fruit is poor, and the low phenomenon of generating efficiency becomes apparent in low wind speeds.
Summary of the invention
The present invention In view of the above shortcomings of the prior art, proposes a kind of stator for wind-driven generator, especially needle
Wind energy recycling to low wind speeds.
The present invention is achieved by the following technical solutions:
The present invention includes: stator core and winding wound on it, and stator core includes: ring part and multiple protrusions,
In: the end of protrusion is connected with the inner surface of ring part.
The multiple U-shaped slots of the outer surface radial equipartition of the ring part, the U-shaped slot and protrusion are correspondingly arranged and axis
Identical, each axis meets at the center of ring part, convenient for being evenly arranged winding.
The top of the protrusion is equipped with the cambered surface of indent, and the horizontal length of the cambered surface is greater than the end of protrusion, so as to around
Group stablizes installation.
The cambered surface of multiple protrusions forms the inner hole for installing stator core, the center of the inner hole and ring part
Center is overlapped.
In order to advanced optimize the generating efficiency in the case where low wind speed, the stator core outside diameter and stator iron
The ratio of the diameter of bore of core is 3.3-4.3;The ratio of the thickness of the outside diameter and stator core of the stator core is
4.0-4.8;The ratio of the width of the width and ring part of the protrusion is 2.8-3.8.
Technical effect
Compared with prior art, the present invention passes through the dimensional parameters of the dependency structure of optimization generator unit stator component, so that
Generating efficiency gets a promotion, especially in case of lower wind speeds.
