The YZ95A pulsating current traction motor is mainly used for the traction of mining electric locomotives in the CIS market. Here are its specific uses:
- Driving and Traction: It provides power for mining electric locomotives, enabling them to tow carriages loaded with ores and other goods to run on the mine railway tracks. It transports the mined ores from the mining sites to concentrators, storage points or transportation hubs, meeting the large-scale transportation needs of mines.
- Adapting to Harsh Environments: Mine environments are usually harsh, with conditions such as high dust, high humidity and complex track conditions. Thanks to its special design, such as the adoption of six-motion journal bearings and rotatable gear brush holder rings, the YZ95A pulsating current traction motor can work stably in such environments, ensuring the normal operation of the mine transportation system.
- Shunting Operations: In areas such as mine railway stations and marshalling yards, it can be used for shunting operations. Through precise control, different carriages are marshalled and disassembled, or the vehicles are shifted between different lines to achieve efficient transportation organization and scheduling, meeting the transportation arrangements of different materials and equipment in the mine production process.
- Brake Assistance: When the mining electric locomotive needs to slow down or stop, the YZ95A pulsating current traction motor can perform the electric braking function, converting the mechanical energy of the locomotive into electrical energy to generate braking force, making the locomotive slow down or stop smoothly. This not only reduces the wear of mechanical braking devices, but also improves the reliability and safety of braking. Especially in scenarios such as long downhill sections in mines, it can effectively control the vehicle speed.
The rotor mechanism of the YZ95A pulse flow traction motor mainly consists of the following parts:
Armature Shaft
- It is the core component of the rotor, usually made of high-strength alloy steel. It not only supports other components of the rotor but also transmits torque to the wheels of the locomotive to drive the train.
Armature Core
- Composed of silicon steel sheets laminated together, the armature core provides a magnetic path for the excitation magnetic field. Slots are punched on its surface to place armature windings.
Armature Winding
- Usually made of copper wires, the armature winding is placed in the slots of the armature core. When the motor is energized, the armature winding cuts the magnetic lines of force of the stator magnetic field to generate induced electromotive force and current, and then interacts with the magnetic field to produce electromagnetic torque, which is the key part to realize the energy conversion of the motor.
Commutator
- The commutator is generally made of copper segments insulated from each other. It is installed at one end of the armature shaft and cooperates with the brushes. Its function is to convert the alternating current in the armature winding into direct current output, ensuring that the electromagnetic torque of the motor has a constant direction and enabling the motor to rotate stably.
Fan
- Installed on the armature shaft, the fan is mainly used for cooling. During the operation of the motor, the fan rotates with the rotor to drive the air flow and dissipate the heat generated by the motor to ensure the normal operation of the motor.
