Embodiment Construction

[0009] Such as figure 1 , figure 2 As shown, the utility model includes a stator iron core and a rotor iron core, and is characterized in that: the stator punching sheet and the rotor punching sheet all use one punching sheet, the rotor punching sheet is a two-pole motor rotor punching sheet 3, and the rotor punching sheet 3 two A herringbone groove 1 is opened in the first magnetic pole shoe, and a permanent magnet and a magnetizer are placed in the groove. The permanent magnet plays the role of dividing the magnetic field. There are also two trapezoidal slots 8 in the rotor sheet, and the rotor excitation winding 4 is wound in the slot, and the rotor excitation winding 4 is connected with a rectifier diode to form a self-rectification electric excitation. The rotor core is evenly divided into two sections, the N pole permanent magnet 2 is placed on the left section, and the N pole permanent magnet faces upwards, and the S pole permanent magnet 7 is placed on the right sec...

Abstract

The invention relates to an internal-magnet division permanent magnetic single-phase generator, which comprises: a stator iron core and a rotor iron core, wherein the invention is characterized in that: the stator stroke plates all use one kind; two magnetic shoes have herring groove; the groove is arranged with permanent magnet and magnetic conductor; the permanent magnet can divide magnetic field; the rotor stroke plate has two trapezoidal grooves; the groove contains activate winding. The invention has the advantages that: (1), it mixes the permanent magnet, division magnet and impulse electromagnet to activate magnetic field, with high stabilize accuracy, while the pressure adjusting rate is lower than 3%, and the efficiency is higher than 85%; (2) it only uses one kind of rotor stroke plate, one stator stroke plate, without brush, and the axial length is short; (3) the stator single-phase winding is one special short coiled one, to shorten the end of two-electrode motor, with better wave shape and less consumption; (4), the generator can be adjusted voltage externally.

Description

technical field [0001] The invention relates to a built-in magnetic pole split permanent magnet single-phase generator. Background technique [0002] At present, it is difficult to adjust the voltage of permanent magnet generators. For this reason, there are many excitation schemes of hybrid excitation, but these schemes often need to increase the axial length and make two machines and multiple machines, which makes the structure complicated and the cost rises, so it is difficult to popularize . Contents of the invention [0003] The purpose of the present invention is to provide a built-in magnetic pole split permanent magnet single-phase generator, which can be externally regulated, and has short axial length, simple process and convenience. [0004] The present invention is achieved in this way, it includes stator iron core and rotor iron core, its characteristic is: stator punching sheet and rotor punching sheet all use a kind of punching sheet, and this rotor punchin...
