Abstract
The utility model discloses a pivot-alike dual-frequency / variable frequency brushless motor with a structure that a frequency motor and an intermediate frequency motor share the same pivot. A frequency excitation machine and an intermediate frequency have a pivot-alike structure. Therefore, the pivot-alike dual-frequency / variable frequency brushless motor is similarly made by two motors with the same axes, which realizes both the brushless and pivot-alike, and then reduces the volume greatly and enhances the performance. Meanwhile, the frequency motor in variable frequency can be operated as an asynchrony start-up synchronic motor, and the synchronic motor control is executed by an electromagnetic component, thereby enhancing greatly the reliability without an electronic component on the rotor (such as without a controlled silicon component). All the set of windings exert influence to one another, which thus make the electrical magnet a good compatibility.
Description
Technical field
The utility model relates to power-supply device, refers more particularly to a kind of Coarmature type two-frequency variable-frequency brush-free generator.
Background technology
Double frequency/frequency conversion generator has been mainly brush configuration, and the brush configuration slip ring is arranged, and brush damages easily, produces spark and produces interference, has brush double frequency/frequency conversion with the pivot generator interference to be arranged mutually, and voltage waveform distortion is serious.A lot of occasions can not be used.In recent years Kai Fa double frequency/different pivots with intermediate frequency of frequency conversion brushless generator main frame power frequency are two independently motors.Reason also is due to an electrical interference difficult problem is forced to.Make the motor axial length very long, motor is economical inadequately and reliable, has the position limit place not use.The controllable silicon long-time running is arranged on the rotor, and environment is abominable, and task is heavy, is insecure hidden danger.In addition, existing double frequency/frequency conversion generator is single-phase can not be general with three-phase, brought inconvenience to the user.
Summary of the invention
The purpose of this utility model is at above-mentioned situation, the double frequency/frequency conversion brushless generator of design Coarmature type.Also noiseless when making, single with pivot, three-phase is general, the controlled member of long-term work has so not only improved properties of product greatly, and has improved reliability greatly on the cancellation rotor.
The technical solution of the utility model is: a kind of Coarmature type double frequency/variable-frequency brush-free synchronous electric generator, and double frequency/frequency conversion main frame is totally one armature, and power frequency, intermediate frequency exciter be totally one armature.Complete machine is by two combined type motor coaxial compositions.Its power frequency motor stator is made of two cover windings, and a cover main winding is single double-deck lap winding type three-phase symmetric winding, and the auxiliary winding of a cover is two repeatedly formula three-phase symmetric windings, and the every circle number of turn of main winding is 2 times of the auxiliary every circle number of turn of winding.Its intermediate frequency motor stator is made of two cover windings, one cover main winding is that single double-deck lap winding type three symmetrical fractional slot winding constitute, the auxiliary winding of one cover is two repeatedly formula three symmetrical fractional slot winding, and the every circle number of turn of main winding is 2 times of the auxiliary every circle number of turn of winding.Main rotor power frequency winding is to be made of two cover windings, and two cover windings in series connect, and all be the equal-turn type winding, but the number of turn of the every circle of compound winding are 15% of the every circle number of turn of main winding.Various windings all are to wait the circle structure.
Advantage of the present utility model is: 1) realized non-brushing, the spark that does not have slip ring, brush to produce disturbs; 2) realize co-gearing, shortened the axial length of motor greatly; 3) nothing interferes with each other, and Electro Magnetic Compatibility is good; 4) singly, three-phase can be general, the perfection of generator voltage waveform sine; 5) there is not electronic component, the reliability height on the frequency variable synchronous motor operation control rotor.
