Abstract
The utility model relates to a motor, in particular to a variable frequency speed changing asynchronous traction motor for light rail underground railway vehicle, a commutator arranged according to the switchover requirement on a DC traction motor is the most serious defect, the commutator is difficult in manufacturing and maintenance, an all-around fire is easily caused during the operation to burn the motor, and the end of a stator coil in the utility model is welded, and the combined application of the technologies such as a rotator ring-protection and the dust-filtering of the air filter, etc. can improve the reliability of motor operation, the commutator and some accessories relating to the switchover process can be canceled, the motor structure is largely simplified.
Description
The utility model relates to a kind of motor, the variable-frequency control asynchronous traction motor of particularly a kind of light rail railcar.
The light rail railcar is as metropolitan main vehicles at present, along with the urban passenger flow amount constantly increases, more and more higher to the light rail railcar with main traction motor performance requirement, DC traction motor can't satisfy vehicle to its performance demands, dc traction motor is its greatest drawback because of the commutator that commutation requires to be provided with, it is difficult in maintenance that commutator is made, and in use cause ring fire easily and burn out motor.
The purpose of this utility model is to provide a kind of communtatorless ac variable frequency speed regulation asynchronous traction motor, and electric machine structure is simple, can satisfy light rail subway car gently to the requirement of traction motor.
The utility model is finished with following mode: variable-frequency control asynchronous traction motor comprises composition (see figure 1)s such as end cap (1), air cleaner (2), stator (3), rotor (4), stator coil (5).(see that Fig. 2-B) is locked two lead-in wires (6) of adjacent windings, (7) with copper sheathing (8) welds that back outsourcing insulation is latent to be loaded in the two coil nose gaps to stator coil (5) parts line, has shortened the axial length of motor stator greatly.Rotor end bell is fastening (sees Fig. 3-C) rotor bar (11) and end ring (9), after the welding, at end ring (9) cylindrical at a groove, retaining ring (10) interference is fastened in the groove of end ring (9) cylindrical, and retaining ring need be with traditional end face or cylindrical double-screw bolt fastening means and destroyed the overall structure and the mechanical strength of retaining ring like this.(see Fig. 4-A), be provided with swirl vane (13) at air cleaner inwall (12) one ends, the other end is provided with filter interior separation chamber (14) guiding tube (15) to air cleaner.Cooled external air is when entering air cleaner, to advance by swirl vane (13) spiral, air is when spiral advancing, rely on action of centrifugal force, after separation such as dust in air, foreign material, advance along filter inwall (12), by the inner separation chamber (14) of dirt catcher, cleaned air is separated with dust impurity, cleaned air enters motor internal after passing through in separation chamber's item 14, and the dust foreign material enter guiding tube (15) along dirt catcher inwall (12), guiding tube (15) connects the motor outlet, relies on the blast of motor outlet that the dust foreign material are discharged.
Fig. 1 is the utility model structural representation
The local enlarged diagram of stator coil parts line in Fig. 2-B the utility model
Fig. 3-fastening local the enlarged diagram of C the utility model rotor retaining ring
The local enlarged diagram of air cleaner in Fig. 4-A the utility model
Below in conjunction with accompanying drawing the utility model is further described
As Fig. 1; Fig. 2; Fig. 3; shown in Figure 4; the variable-frequency control asynchronous traction motor of the utility model light rail railcar; be applicable on light rail vehicle and the railcar; because it has cancelled commutator and some annexes relevant with commutator; simplified electric machine structure greatly; under equal volume; increased capacity motor; and the asynchronous machine characteristic has natural anti-idle running performance; the wearing and tearing of wheel and track have been protected effectively; stator end in the utility model welding in addition; the The Application of Technology such as filtration dust of rotor end bell protection and air cleaner have improved the motor reliability of operation, make motor in the running of whole vehicle; need not to safeguard that really structure has accomplished to use no maintainability on the principle.In city afterwards and the rail vehicle evolution, will replace dc traction motor.
Claims (2)
1, a kind of light rail railcar uses variable-frequency control asynchronous motor by end cap (1), air cleaner (2), stator (3), rotor (4) stator coil compositions such as (5), it is characterized in that stator coil (5) parts line is two lead-in wires (6) with adjacent windings, (7) with copper sheathing (8) cover postwelding outsourcing insulation, latent being loaded in the two coil nose gaps, in the rotor (4), ring expansion (10), be anchored in the groove of end ring (9) cylindrical, inwall one end of air cleaner (2) is provided with swirl vane (13), and the other end is provided with filter interior separation chamber (14) and guiding tube (15).
2, according to the described variable-frequency control asynchronous motor of claim 1, it is characterized in that rotor bar (11) and end ring (9) welding after, at groove of end ring (9) cylindrical car, retaining ring (10) interference is fastened in the groove of end ring (9) cylindrical.
