Crawler tractor

Railway mains electric locomotives, industrial and mining electric locomotives, electric drive diesel locomotives and various electric vehicles (such as battery vehicles, Motors for traction on city trams and underground railway electric vehicles.

A motor used to drive one or several moving axles on a locomotive or motor train. There are many types of traction motors, such as DC traction motors, AC asynchronous traction motors and AC synchronous traction motors. DC traction motors, especially DC series-excited motors, have better speed regulation performance and working characteristics, and are suitable for the traction characteristics of locomotives and have been widely used. The working principle of the traction motor is the same as that of the general DC motor, but it has special working conditions: the space size is limited by the gauge and the diameter of the moving wheel; it must withstand considerable impact vibration when the locomotive runs through the rail joint and the ballast; large and small gears When the meshing is poor, strong torsional vibration is generated on the armature; in harsh environments, rain, snow, and sand are easily invaded. Therefore, the traction motor also has many requirements in design and structure. For example, to make full use of the internal space of the body to make the structure compact, it is necessary to use higher-grade insulating materials and magnetic conductive materials, and the parts need to have higher mechanical strength and rigidity, and the whole motor It is necessary to have good ventilation and heat dissipation conditions and dust and moisture resistance. Special measures should be taken to cope with the difficult "commutation" conditions to reduce sparks under the carbon brush.

Our company constantly draws on advanced technology from Europe, America and Japan, and the main components used in the machine are original products from Sakamoto, Taiwan and the United States, which can better produce high-speed extruders and high-speed extruders with advanced levels. Silicone extrusion production line, high-speed electric control cutting machine, high-speed stranding machine and high-speed electric control stranding machine, cable-forming machine. So far, merchants from Central Europe, South America and South Africa have especially appreciated the quality of our company's products, which has given us great appreciation.
