Abstract
A permanent magnet excitation control device comprises a mounting support, a permanent magnetic motor stator, a permanent magnetic motor rotor, a cylindrical pin and a bolt. The permanent magnetic motor rotor is equipped with a permanent magnet, and has an invariant magnetic field. The permanent magnetic motor stator is connected with the mounting support via the bolt. The permanent magnetic motor rotor is connected with the rotating shaft of a generator via the cylindrical pin and the bolt. The mounting support can be manufactured to be the rear end cap or the rear bearing cover of the generator, and then is arranged on the generator via the bolt. The device of the utility model enables invariant excitation sources to be provided to an AC generator, allows the transient regulation rate of the generator to be high, and allows the dynamic performance of the generator to be fine. Moreover, the excitation device has the characteristics of small size, simple structure, convenient mounting or the like, and is especially suitable for being used on medium and small generators.
Description
Technical field
The utility model relates to a kind of permanent magnet excitation control device.
Background technology
Generally the excitation mode of alternating current generator has first-harmonic excitation, phase compound excitation excitation etc.; The first-harmonic excitation is because excitation source is taken from the armature winding of generator; The voltage of this winding changes with the variation of load; Cause generator transient state regulation low, bad dynamic performance, the phase compound excitation excitation controlling device has shortcomings such as volume is big, complex structure, price height.
Summary of the invention
Characteristics such as the purpose of the utility model is to provide a kind of permanent magnet excitation control device, and this apparatus structure is simple, easy for installation are particularly suitable on medium and small generator, using.
The technical scheme of the utility model does; It comprises mounting bracket, permanent magnetic motor stator, permanent magnetic motor rotor, straight pin and bolt; It is characterized in that on the permanent magnetic motor rotor permanent magnet being housed, the permanent magnetic motor stator links to each other with mounting bracket through bolt, and the permanent magnetic motor rotor links to each other with alternator shaft through straight pin and bolt; Mounting bracket can be made the rear end cap or the rear bearing cover of generator, is installed on the generator through bolt again.
The technique effect of the utility model is: because the permanent magnetic motor rotor has constant magnetic field; This device can provide constant excitation source for alternating current generator; Make generator transient state regulation high; Dynamic property is good, and this excitation unit has characteristics such as volume is little, simple in structure, easy for installation, is particularly suitable on medium and small generator, using.
Description of drawings
Fig. 1 is the structural representation of the utility model.
In the drawings: 1. mounting bracket 2. permanent magnetic motor stators 3. permanent magnetic motor rotors 4. straight pins 5. bolts.
Embodiment
As shown in Figure 1, the utility model is achieved in that permanent magnetic motor stator 2 links to each other with mounting bracket 1 through bolt; Permanent magnetic motor rotor 3 links to each other with alternator shaft through straight pin 4 and bolt 5; Under the driving of prime mover, rotate with the main rotor of generator, produce constant rotating magnetic field; Thereby make permanent magnetic motor stator 2 produce constant exciting voltage, as the excitation source of main generator.Mounting bracket 1 can be made the rear end cap or the rear bearing cover of generator, is installed on the generator through bolt again.
