Abstract

Disclosed is a linear generator primary. The linear generator primary comprises a sectional type primary stator core and a sectional type primary winding, wherein the primary stator core and the primary winding are segmented in a vertical direction so as to form multiple primary stator core units and primary winding units. Primary stator wire ducts (6) are arranged at uniform intervals at one side, facing a secondary, of each primary stator core unit, each primary winding unit is embedded in the primary stator wire ducts (6) of the corresponding primary stator core unit so as to form a primary unit. Projection portions between adjacent primary stator wire ducts (6) are primary stator teeth (5). The length of the primary unit disposed at the center of the secondary is the longest, and the length of the primary unit distanced furthest from the center of the secondary is the shortest. Two primary winding units symmetrically arranged along the center of the secondary control on-off through one electric and electronic device. The linear generator primary can be applied to a point absorption direct-driven wave energy power generation system.

Description

technical field [0001] The invention relates to the technical field of wave energy power generation, in particular to a long secondary and short primary linear generator applied to a direct-drive point absorption wave energy power generation system. Background technique [0002] The point absorption wave energy power generation system refers to a power generation system in which the size of the floating buoy used to capture energy is much smaller than the wavelength of the wave. The system can usually be divided into direct drive type and non-direct drive type. In non-direct drive systems, the float is connected to a speed increasing device such as a pneumatic system, a hydraulic system or a gearbox, and then connected to a rotating generator. The non-direct drive system is small in size, but its intermediate links are complicated, which reduces the reliability and conversion efficiency of the system. The direct drive system floats are directly connected to the linear gener...
