Turbofan-type double-blade horizontal axis axial torque balance wind turbine generator

Abstract

The invention discloses a turbofan-type double-blade horizontal axis axial torque balance wind turbine generator which comprises a spindle, an inner rotor impeller group, an outer rotor impeller group, a generator outer rotor shell, an armature collector ring, an electric brush, an electric brush wiring terminal, an excitation conductive sliding ring, an excitation sliding ring electric brush, an electric brush wiring terminal, a fixed single-side end cover and a base frame. According to the generator, the outer rotor impeller group and the inner rotor impeller group are not superposed along the wind direction, so the wind energy can be effectively captured; and moreover, the forward and backward impellers are utilized, so that the rotor and stator of the generator rotate simultaneously, the relative rotating speed is increased, and the power generation efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of power generation equipment, in particular to a wind energy generator. Background technique [0002] At present, the global energy shortage, countries have stepped up to speed up the development and utilization of renewable energy, scrambling to develop methods that convert natural energy from non-electric energy into electrical energy through certain technical means and use it. Among many power generation methods, wind power generation It is a very good form of use. At present, the main types of wind energy generator stations in my country are vertical axis and horizontal axis. The principle is to convert wind energy into the rotation of the impeller, and then transmit the kinetic energy to the generator through the transmission device. In the prior art, the design of the generator is usually fixed on the tower with a stator structure, and the rotor passes through the fan impeller and rotates through a m...

Problems solved by technology

The obvious defect of this structure is that although there is no direct frictional contact between the rotor and the stator, the magnetic field lines in the stator's magnetic field will firmly attract the iron core in the rotor coil through the air gap between the rotor and the rotor, making it A strong electromagnetic resistance is formed. When the wind blows the rotor blades to rotate, this resistance will be transferred to the body of the car through the base of the stator and the generator, so that the electric car can move forward on the basis of the original driving power. This part of the resistance power is increased. According to the principles of classical mechanics, the wind force acting on the impeller will twist the rotor to rotate and cut the magnetic force lines in the stator magnetic field. At this time, the stator magnetic field will also generate a reaction force.
