Description

Railcar 132KW DC traction motor

The utility model relates to a kind of motor, particularly a kind of railcar 132KW DC traction motor.

Railcar is as the development of metropolitan main vehicles along with the city at present, the volume of the flow of passengers is constantly increasing, and it is also just more and more higher to railcar with the performance requirement of main traction electric machine, China's railcar with main traction electric machine from 76KW, 86KW to 98KW, its traction power is constantly increasing, but still does not satisfy the requirement that the real volume of the flow of passengers increases.

The purpose of this utility model is to provide a kind of energy to satisfy the railcar 132KW DC traction motor of existing subway motor volume requirement.

The utility model is finished with following mode: railcar comprises stator 3, rotor 7 with the 132KW DC traction motor, end cap 2, stator 3 has four main poles 4 and four pairs of utmost points 6, the groove number of armature stamping 5 is 42 grooves, and armature stamping 5 and armature coil 8 and commutator 9 are housed on rotor 7, and the copper segment number is 168, the serial connection excitation, motor profile length overall 824mm, high 705mm, wide 750mm.The groove width that a left side on the motor housing hangs angle 11 is 45mm, its groove center line is 317mm to the armature center, it is 400mm that a left side hangs 11 bottom land planes, angle to left footing 12 screw centers, footing 12 planes, a left side are 267mm to the armature center, the motor center height is 280mm, motor shaft extension circular cone major part is φ 70mm, and the circular cone effective length is 70mm, and taper ratio is 1: 10.

The utility model railcar is used as the main traction electric machine of railcar with the 132KW DC traction motor, satisfying under existing gauge and the situation of vehicle wheel diameter, motor volume guarantees original place iron machine constancy of volume substantially, power of motor is brought up to 132KW, satisfy the requirement of real volume of the flow of passengers increase the vehicle towed motor of subway.

Fig. 1 is the utility model structural representation.

Fig. 2 is the cross-sectional structure schematic diagram of Fig. 1.

Below in conjunction with accompanying drawing the utility model is described in further detail:

As shown in Figure 1 and Figure 2, the utility model railcar is made up of stator 3, rotor 7, end cap 2, bearing 1,10 with the 132KW DC traction motor.Power of motor is 132KW, and voltage is 750/2V, and electric current is 390A, rotating speed 1580r/mm, and the class of insulation is the H level, excitation mode adopts series excitation.Stator 3 has four main poles 4 and four pairs of levels 6.Installing rotor 7 on the bearing 10 of bearing on the electric motor end cap 21 and support 3 right-hand members, installing commutator 9 and armature stamping 5 and armature coil 8 on rotor 7.The groove number of armature stamping 5 is 42 grooves, and the copper sheet number of commutator 9 is 168, and brush is installed in support 3 right-hand members.Can remain on the raising power of motor like this and reach railcar 132KW, and its overall volume can satisfy the requirement of railcar.Motor profile length overall is 824mm, high 705mm, wide 750mm, the groove width that a left side hangs angle 11 is 45mm, as shown in Figure 2, the groove center line that a left side hangs angle 11 is 317mm to the armature center, and it is 400mm to left footing 12 screw centers that a left side hangs 11 bottom land planes, angle, and left footing 12 planes are 267mm to the armature center, the motor center height is 280mm, motor shaft extension circular cone major part is φ 70mm, and the circular cone effective length is 70mm, and taper ratio is 1: 10.
