The rotor is composed of an armature core (5), an armature winding (4), and a commutator (9). A stator is positioned in the seat (1). An electric brush (10) and an electric brush handle (11) are fixed onto a rear end cap (13), after being connected with an electric brush frame (12). The utility model is characterized in that the stator is composed of a stator iron core (6), and an upper and a lower excitation winding (7, 8), which are respectively inserted in the groove of the stator iron core (6).
Description
Technical field
The utility model relates to the special-purpose series-wound motor of a kind of track traffic, and the power supply that specifically is used for underground railway track, light railway, ground rail circuit breaker is controlled automatically, belongs to the control device technical field.
Background technology
The special-purpose series-wound motor of track traffic is the motor with brush-commutated device, during the series machine operation, when the armature loop of rotation enters another branch road from a branch road through brush, in by the process of brush short circuit, electric current in the element is converted to opposite direction from original direction, and this process just is commutation process.Commutation process is very complicated, and it is not only the change procedure of electromagnetism, but also is subjected to the influence of factors such as machinery, chemistry, ionization.Usually in the moment of commutating spark can appear, in JB-1135-77 single phase alternating current (A.C.) series machine standard, grade of spark when being defined in nominal load on the commutator should be above 2 grades, as strong spark takes place in the good general of commutating not under brush, influence the normal operation of motor, even damaging brush and commutator face, motor may damage when serious, and motor can not be worked on.Therefore the size of commutation spark is the important indicator of series machine running quality.
In prior art, series machine mainly is made up of stator, rotor, armature spindle, electric machine casing, brush, brush holder, brush carrier, rear end cap etc.Stator is made up of stator core and exciting bulk winding and is arranged in the electric machine casing.Rotor is made up of armature core, armature winding and commutator etc.Brush and brush holder are fixed on the rear end cap after being connected on the brush carrier.The series machine of this kind structure is in order to improve commutation, reduce spark, normally adopt following several modes: 1, brush reverse rotational direction offset geometry neutral line certain angle always, both produced degaussing d-axis magnetic potential, the induced potential that reduces again in the commutation element improves commutation; 2, the induced potential in the commutation element is bigger, and then big from the energy that commutation element outwards discharges in the moment of commutating, the spark that causes is just bigger; 3, the element number of turn the more, reactance potential is bigger, it is more unfavorable commutate, obviously chooses the effective way that the little element number of turn is the reduction reactance potential when design; 4, the mutual inductance electromotive force of armature component: usually only consider the mutual inductance electromotive force between the levels component outline in juxtaposed component produces in the armature slot mutual inductance electromotive force and the groove when design, and the mutual inductance electromotive force is big, commutation spark is just big.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned weak point, thereby provides a kind of track traffic special-purpose series-wound motor, and its commutation ability is good especially, commutation spark is minimum, driving moment is big, stable and reliable for performance; Can reduce the wearing and tearing of brush, commutator face is easy damaged not; Noise in the time of reducing commutation has improved useful life greatly.
Main solution of the present utility model is achieved in that
The utility model mainly adopts armature spindle is installed in foundation mass, rotor is housed on the armature spindle, rotor is made up of armature core, armature winding and commutator, stator is arranged in the foundation mass, after being connected on the brush carrier, brush and brush holder be fixed on the rear end cap, it is characterized in that stator reaches following field winding by stator iron and last field winding and forms, field winding is set in the stator core slot respectively up and down.
Described stator core is provided with groove.
Compared with the prior art the utility model has the following advantages:
The utility model is simple, compact and reasonable for structure; Because adopt two independently field windings up and down, two field windings work independently respectively when operation, mutual inductance electromotive force summation reduces greatly, and commutation ability obviously improves, and commutation spark obviously reduces, and grade of spark is all less than 11/4 grade; Owing to after improving commutation spark, thereby reduced the temperature rise of motor, reduced the wearing and tearing of brush, commutator face is easy damaged not, thus the noise when having reduced commutation; Driving moment is big, can be reliable and stable, reduced wireless interference, and can AC/DC, improved this motor useful life greatly.

Embodiment
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model mainly is made up of foundation mass 1, bearing 2, armature spindle 3, armature winding 4, armature core 5, stator core 6, last field winding 7, following field winding 8, commutator 9, brush 10, brush holder 11, brush carrier 12, rear end cap 13 and motor cover 14 etc.
As shown in Figure 1: the utility model stator is arranged in the foundation mass 1, stator by stator core 6 and two independently go up field winding 7 and down field winding 8 form, field winding 7,8 is set in respectively in stator core 6 grooves up and down.Its effect is to produce magnetizing flux, when operation clockwise on field winding 7 work independently; Field winding 8 works independently moving at present counterclockwise, does not have the mutual induction electromotive force each other, and stator is connected the whole motor of support with foundation mass 1.Armature spindle 3 is installed in foundation mass 1, is adopted bearing 2 to support, 2 bearings 2 are contained in the foundation mass 1 respectively and in the bearing chamber of rear end.On the armature spindle 3 rotor is housed, rotor is made up of armature core 5, armature winding 4 and commutator 9, be fixed on the rear end cap 13 after brush 10 and brush holder 11 are connected on the brush carrier 12, motor cover 14 is connected on the rear end cap 13, but can direct current supply also Alternating Current Power Supply.
Shown in Fig. 2,3: power supply U1 connects field winding 7 and is connected in series to power end U with armature
0Be clockwise commentaries on classics: U in like manner
2To U
0Be counterclockwise commentaries on classics.
Because last field winding 7, following field winding 8 work independently respectively when operation, when 7 work of field winding in the clockwise operation, following field winding 8 is not worked, and in the following field winding 8 last field winding 7 and armature component is not all induced the mutual inductance electromotive force; In the time of should moving down field winding 8 work together counterclockwise, last field winding 7 is not worked, in the last field winding 7 following field winding 8 and armature component are not all induced the mutual inductance electromotive force, thereby mutual inductance electromotive force summation reduces greatly, commutation ability obviously improves, commutation spark obviously reduces, and through repetition test repeatedly, grade of spark is all less than 11/4 grade.
