Abstract
The invention relates to a large-scale magnetic suspension circular orbit combined type three-phase alternator. The alternator is characterized in that the alternator utilizes multi-block homopolarity strong magnet which is matched with a circular orbit magnetic suspension and arranged on a round air impeller as a generator rotor, multiple group three-phase electromagnetic coils which are fixed on a circular orbit, of a silicon sheet core is utilized as a generator stator, and the generator rotor and the generator rotor combine into multiple group independent three-phase alternators; and each generator is used in a mode of same phase in series or parallel connection of A, B and C, therefore multiple group small generators combine into a large-scale three-phase alternator according to need.
Description
Affiliated technical field
Polylith list homopolarity strong magnet on the round shape fan blade that utilization of the present invention and circular orbit magnetic suspension cooperate is as generator amature; Use the many groups three-phase electromagnetic induction coil that is fixed on the silicon steel label on the circular orbit as generator unit stator; Both are combined into and organize independently threephase alternator more; Can A, B, C three-phase homophase serial or parallel connection be used, and can be combined into a large-scale threephase alternator on demand more with organizing small generator between each generator.
Background technique
The present invention is applied to me to apply on October 19th, 2010, and application number is 201010526558.5, existing a kind of combined large threephase alternator division embodiment in " the large magnetic suspension circular orbit wind-driven generator " announced on April 13rd, 2011.
Summary of the invention
In order to let " large magnetic suspension circular orbit wind-driven generator " to organize small generators under the situation of serial or parallel connection combination more; Become and to unify the threephase AC that output A, B, its sinusoidal waveform of C respectively differ 120 degree phase angles; The utility model changes single one group silicon steel label induction coil on ternary silicon steel label and respectively enclosing around the three-phase electricity induction of one group of winding; And it is evenly distributed be installed in circular orbit two rails middle part as stator; On fan blade, load onto many groups same polarity strong magnet of matching with induction coil again as generator amature; Under the promotion of wind-force to fan blade, the combined power generation machine can be by the threephase AC of the specified voltage and current of different needs output difference.
The technological scheme that the present invention solves its technical problem employing is: under the fan blade situation that magnetic suspension cooperates with the circle magnetic orbital; Be contained in that magnet width that rotor that fan blade bottom and three-phase induction circle cooperate uses is the same with single-phase induction circle iron core width to be u; The magnet of adorning and induction coil fitting surface be homopolarity N or S face; And evenly install according to adorning the empty 3u of magnet space, induction coil chevron silicon steel label each mutually between permeability be 1, spacing is 1/3rd u; All silicon guiding principle labels that belong to a phase together are regardless of the magnet movement situation during installation, and all these phase silicon steel labels and magnet positions distance equate simultaneously.
The invention has the beneficial effects as follows: change single-phase generator Ac output unit into three phase generator Ac output unit; Can simplify electric energy output through combinations such as series, parallel; Improve whole generator efficient, this has created advantage for wind-powered electricity generation ACVV, rectification, dc inversion etc., simultaneously as three phase current combined large generator; Can significantly practice thrift manufacturing, transportation, installation, maintenance cost, simple in structure.
