Yet this engine has big quality and size, makes complexity, and power frequency is 50Hz, and only could realize when rotor high-speed rotates, and use in the design of wind-force unit is unallowed for generator for this.
Immediate with the present invention is the multipole synchronous generator of low speed (referring to Ukraine Gazette of Patent for Invention No.42513, announcing October 15 calendar year 2001).
Described generator comprises stator with three phase windings of being made by coil and the rotor with permanent magnet, and the every utmost point of these coils is arranged a coil and be combined into different coil groups that these permanent magnets are arranged on the yoke along rotor axis.Stator is made with belt n shape segmentation form, but uses ferrite barium magnet as permanent magnet, and the ratio of rotor number of poles and stator poles is 8/9.
Described generator is chosen to be prototype.
Prototype and the present invention have following general features:
-stator is made with n shape segmentation form, has the winding of being made by stator coil;
The every utmost point of-stator coil is arranged one;
-stator coil is combined into different coil groups;
-rotor;
-permanent magnet, along rotor arrangements on yoke.
But in the design of the low-speed generator of prototype, the power that produces when magnetic field interaction in the radial direction is applied and reaches sizable value.Therefore need to increase the quality of generator.
Summary of the invention
The purpose of this invention is to provide the multipole synchronous generator of a kind of low speed, wherein, rotate 90 with respect to rotor axis by the magnetic conductor that makes stator coil
And make the working clearance move to the end surfaces of rotor, and eliminate interactional radial load, make the interaction force localization in magnetic field, and the quality and the size index that reduce generator.
According to an aspect of the present invention, provide a kind of low speed multipole synchronous generator, having comprised: stator, it is made with n shape segmentation form, has the winding of being made by stator coil, and the every utmost point of these stator coils is arranged a coil and is combined into different coil groups; And rotor, it has permanent magnet, these permanent magnets along rotor arrangements on yoke, rotor is made with the disk-form with the insert that is made of permanent magnet, these permanent magnets are alternately fixing with respect to the direction of magnetization, epitrochanterian permanent magnet is installed with respect to the magnetic conductor circumferential displacement ground of stator coil by this way, and the magnetic conductor layout opposite each other of promptly per the 10th permanent magnet or stator coil is as the criterion with an extremely more side.
The invention provides a kind of design of the multipole synchronous generator of low speed of process improvement, wherein, magnetic conductor by making stator coil is with respect to the rotor axis half-twist and make the working clearance move to the end surfaces of rotor, eliminate interactional radial load, make the interaction force localization in magnetic field, and the quality and the size index that reduce generator.
In the multipole synchronous generator of the low speed of prototype, the power that produces when magnetic field interaction is applied and reaches sizable value, and this makes design restricted.
