Transverse magnetic field linear generator adapting to variable-speed operation within low-speed range

Abstract

The invention provides a transverse magnetic field linear generator adapting to variable-speed operation within a low-speed range. The transverse magnetic field linear generator comprises a stator and a rotor, wherein the stator comprises stator cores, a stator fixing shaft and stator windings; the rotor comprises rotor cores, first permanent magnets, second permanent magnets and first non-magnetic conducting material structures; each stator core and the corresponding stator winding assembled in stator slots in the stator core form one phase of the stator, so that implementation of modularization is achieved; the number of phases of the generator and the arrangement mode among the phases are not limited; the number of poles of the generator is increased; on one hand, the stator and the rotor can be freely combined according to the amount of to-be-converted energy, and on the other hand, the generator can obtain relatively high output voltage during low-speed operation; the wire length of a single-phase armature coil of the generator for effectively cutting a magnetic line is increased by the structure, so that the magnitude of single-phase output voltage of the generator is increased, the low-speed output capability of the generator is improved and improvement of the energy conversion efficiency of the generator is finally facilitated.

Description

technical field [0001] The invention relates to a generator, in particular to a transverse magnetic field linear generator suitable for variable-speed operation in a low-speed range. Background technique [0002] The generator is a kind of equipment that has been widely used at present. However, the existing generators basically need to work at a high speed to reach their rated operating conditions, and only when they are near the rated motion can they achieve higher energy. Conversion efficiency, which limits the use of generators in low-speed and unstable energy fields such as wind energy and ocean energy. [0003] Today, when the world's energy is increasingly scarce, green renewable energy such as wind energy and ocean energy has become an important energy source that people continue to develop and utilize. Therefore, it is particularly important to design a linear generator that can adapt to low speed and operate efficiently in a wide speed range. important. Contents...
