Magnetic-suspension type relative rotation generator

Abstract

The invention discloses a magnetic-suspension type relative rotation generator, and the generator comprises a housing. The interior of the housing is provided with a cavity, and the surface of the housing is provided with an opening. A stator shaft passes through the opening and stretches into the cavity. One end, located outside the cavity, of the stator shaft is connected with a stator driving mechanism. One end, located in the cavity, of the stator shaft is connected with a stator disc. The stator disc is provided with a plurality of groups of stator silicon steel sheets. The stator shaft is sleeved by a rotor shaft, wherein one end, located outside the cavity, of the rotor shaft is connected with a rotor driving mechanism, and the other end of rotor shaft is provided with a rotor disc. The bottom of the stator disc is provided with a stator magnetic-suspension type rolling bearing, and the surface of the rotor shaft is provided with a rotor magnetic-suspension type rolling bearing. The generator provided by the invention is simple in structure, and is low in manufacture cost. The stator magnetic-suspension type rolling bearing and the rotor magnetic-suspension type rolling bearing, which are respectively disposed at the bottom of the stator disc and on the surface of the rotor shaft, enable the generator to be suspended magnetically during power generation when the stator silicon steel sheets cuts magnetic force lines, thereby reducing the friction, and achieving higher efficiency.

Description

technical field [0001] The invention relates to a magnetic levitation type relative rotation generator. Background technique [0002] Electricity is transformed from energy. Electricity is an increasingly indispensable form of energy in human civilized society. Therefore, in order to meet the increasing demand for electricity, people do everything possible to develop various energy sources for power generation, such as coal power, Thermal power, hydropower, nuclear power, wind power generation, etc. Among them, hydropower and wind power generation must use generators to convert hydraulic power and wind energy into electrical energy, but the existing generators use the motor structure of the stator and rotor, according to the principle of cutting magnetic lines of force. To generate electricity, this kind of generator has greater friction and lower efficiency. Contents of the invention [0003] In order to solve the defects and deficiencies of the prior art, an embodimen...
