Abstract
The utility model discloses a traction motor for a four wheeler. The traction motor comprises a casing, a rotor component and a stator component; wherein the casing comprises a front cover component, a rear cover component and a fixing plate; the stator component is fixed in the casing; the rotor component is arranged in the stator component, the stator coil assembly of the stator component is formed by winding flat copper wires, and the rotor coil assembly of the rotor component is also formed by winding flat copper wires. The traction motor has the advantages that the stator coil assembly and the rotor coil assembly are formed by winding the flat copper wires, thereby being more compact and having smaller volume than the coil assembly structure formed by winding round copper enamelled wires; besides, the cross section of the flat copper enamelled wires are large, therefore, the mechanical strength and the rigidity thereof are higher, and the bearing capacity is higher.
Description
Technical field
The utility model relates to a kind of motor, particularly a kind ofly is used for the traction electric machine that carriage is used.
Background technology
Traction motor is the motor that is used to drive one or a few axis of a movable block on locomotive or motor-car.Traction motor has polytype, as DC traction motor, alternating current asynchronous traction motor and AC synchronous traction motor etc.DC traction motor, especially D.C. series motor have better speed adjusting performance and operating characteristic, adapt to the needs of locomotive tractive characteristic, obtain extensive use.Its operation principle is identical with general DC motor, but special condition of work is arranged, bulk is subjected to the restriction of gauge and driving wheel diameter, when closing track switch by rail gap, locomotive operation to bear sizable impact shock, can produce strong twisting vibration on the armature during size poor gear engagement, in adverse circumstances, use rain, the easy intrusion of snow dust and sand etc.Therefore traction motor also has many requirements on design and structure, make compact conformation as making full use of the internal body space, adopt higher insulating material and arrive this material, parts need have higher mechanical strength and rigidity, whole motor must have good ventilation and heat condition and dust and moisture ability, take special measure with the commutation condition of dealing with the comparison difficulty to reduce spark under the carbon brush etc.At present, the volume of the coil groups of existing traction electric machine is bigger, does not satisfy the designing requirement of traction locomotive electric machine structure compactness.
Summary of the invention
Goal of the invention
The purpose of this utility model is to provide a kind of carriage traction electric machine at the bulky problem of coil groups of the existing traction electric machine existence described in the background technology.
The realization the technical solution of the utility model is as follows:
A kind of carriage traction electric machine, it comprises housing, rotor assembly and stator module, described housing comprises preceding cap assemblies, rear case component and fixed head, stator module is fixed in the housing, rotor assembly is arranged in the stator module, described stator module comprises stator core made from silicon steel sheet and the sets of stator coils that is wrapped on the stator core, described rotor assembly comprises the armature shaft that is arranged at rotor assembly right-hand member axial centre, be arranged at the commutator on the armature shaft, the rotor core of forming by silicon steel sheet, the drive unit that is wrapped in the rotor coil group on the rotor core and drives the rotor rotation, the sets of stator coils of described stator module forms with the flat type copper wire coiling, and the rotor coil group of described rotor assembly forms with the flat type copper wire coiling.
Tightr for stator module is connected with housing, described stator module is fixed in the housing by hex screw and spring shim.
In order to make drive unit and being connected of armature shaft stressed more even, can bear bigger load, guidance quality is good, the centering precision height, the big described drive unit of transmitting torque is a spline housing.
Be provided with groove in the described rotor coil group and sign and insulating paper, in order to make rotor coil group structure tightr, rotor coil group arranged outside has or not the latitude band.
The beneficial effects of the utility model are for all forming with the coiling of flat copper enamelled wire because of the stator module of motor and the coil groups of rotor assembly, so it is tightr with respect to the coil groups structure that round copper enamelled wire coiling forms, coil groups for same number of turns, the coil groups volume that turns to flat type copper wire is littler, and flat copper enamelled wire sectional area is big, its mechanical strength and rigidity are stronger, and bearing capacity is higher.Because rotor assembly adopts spline housing as drive unit, it is stressed more even with being connected of armature shaft, can bear bigger load, and guidance quality is good, the centering precision height, and transmitting torque is big.
Description of drawings
Fig. 1 is a schematic diagram of the present utility model;
Among the figure, 1 is housing, and 2 is rotor assembly, 3 is stator module, and 4 is preceding cap assemblies, and 5 is rear case component, 6 is fixed head, and 7 is stator core, and 8 is sets of stator coils, 9 is armature shaft, and 10 is commutator, and 11 is rotor core, 12 is the rotor coil group, and 13 is spline housing, and 14 are no latitude band, 15 grooves are signed, and 16 is insulating paper.
Embodiment
With reference to a kind of carriage traction electric machine shown in the accompanying drawing 1, it comprises housing 1, rotor assembly 2 and stator module 3, described housing 1 comprises preceding cap assemblies 4, rear case component 5 and fixed head 6, stator module 3 is fixed in the housing 1, rotor assembly 2 is arranged in the stator module 2, described stator module 3 comprises stator core made from silicon steel sheet 7 and the sets of stator coils 8 that is wrapped on the stator core 7, described rotor assembly 2 comprises the armature shaft 9 that is arranged at rotor assembly 2 right-hand member axial centre, be arranged at the commutator 10 on the armature shaft 9, the rotor core of forming by silicon steel sheet 11, the drive unit that is wrapped in the rotor coil group 12 on the rotor core 11 and drives the rotor rotation, the sets of stator coils 8 usefulness flat type copper wire coilings of described stator module 3 form, and the rotor coil group 12 usefulness flat type copper wire coilings of described rotor assembly 2 form.Tightr for stator module 3 is connected with housing 1, described stator module 3 is fixed in the housing 1 by hex screw and spring shim.In order to make drive unit and being connected of armature shaft 9 stressed more even, can bear bigger load, guidance quality is good, the centering precision height, the big described drive unit of transmitting torque is a spline housing 13.Be provided with groove label 15 and insulating paper 16 in the described rotor coil group 12, in order to make the rotor coil structure tightr, rotor coil group 12 arranged outside have or not latitude band 14.
Because the stator module of motor and rotor assembly coil groups all form with the coiling of flat copper enamelled wire, so it is tightr with respect to the coil groups structure that round copper enamelled wire coiling forms, coil groups for same number of turns, the coil groups volume that turns to flat type copper wire is littler, and flat copper enamelled wire sectional area is big, its mechanical strength and rigidity are stronger, and bearing capacity is higher.Because rotor assembly adopts spline housing 13 as drive unit, it is stressed more even with being connected of armature shaft, can bear bigger load, and guidance quality is good, the centering precision height, and transmitting torque is big.Because need certain force of strain when not having 14 colligations of latitude band, tension force comes colligation greatly about 40-80kg by machine, can make the rotor coil structure tightr.
