Large/Medium-Sized High-Voltage Wound Rotor Motor

Motor frame Motor frame: the use of domestic high-quality 45 # steel plate welded processing, with surface processing size tolerance should be less than 0.01mm, to ensure that the mechanical properties of the motor.   Motor spindle Spindle material forged 45A steel. After quenched and tempered after rough car, fine car, washing, grinding and other processes from processing, to ensure the overall mechanical properties of the spindle and precision tolerance size. Stator rotor core (1) fixed rotor core is the use of low loss, high permeability, high stacking coefficient, the surface of the insulating film adhesion and good weldability, no time, the thickness of 0.5mm electrician high-quality grain non-oriented cold rolling Silicon steel sheet laminated. Cold rolled silicon steel sheet performance indicators should not be less than GB2521-88 requirements, the material used by the performance of not less than 50W310. Each piece of silicon steel sheet should be no burr, both sides coated with F-class insulation material paint to reduce the eddy current loss. (2) fixed rotor core ventilation groove layout so that the air flow smooth and smooth, so that the stator core is fully cooled, the wind resistance loss is small.   Stator winding coil Stator winding coil using domestic high-quality manufacturers to provide the F-class insulation grade enameled wire or double glass fiber flat copper wire wound around. In the manufacturing process after several inter-turn pulse voltage test and ground pressure test. The stator rotor winding is embedded in the core   The stator rotor winding: 100% pure copper flat copper bending, F-class insulation mica wrapped. Stator rotor winding wiring In the manufacturing process with silver copper argon arc welding, and with F-class insulation mica will be welded at the package so the motor insulation performance is excellent and reliable, good mechanical strength, moisture resistance.   Stator winding rotor winding vacuum impregnation Using foreign advanced vacuum pressure impregnation solvent-free paint equipment and process (VPI) treatment. Has a good anti-corona and anti-corrosion resistance, in the groove, the end of the site to take anti-halo measures. Therefore, the motor insulation performance is excellent and reliable, good mechanical strength, moisture resistance. Rotor fine processing and dynamic balance check Rotor fine processing to ensure the stability of the stator and rotor between the uniform Dynamic balancing checks ensure good mechanical performance of the motor.    Machine assembly and experiment experimental projects Mechanical inspection/Determination of DC resistanceDetermination of insulation resistanceNo load testDetermination of vibration and temperature riseDetermination of open circuit voltage of rotorStall testWinding to ground pressureTurnstrap test30KV DC leakage test (only 10KV motor)   Center height range: H355 ~ 1000mmPower range: 185kW ~ 10000kWNumber of poles: 2/4/6/8/10/12Rated voltage: 6000V/6600V/10000V/11000VRated frequency: 50HZ/60HZProtection level: IP54 or IP55Insulation class: FWork system: S1 (continuous)Cooling method: IC611/IC616Installation form: IMB3Motor connection: Y (three outlet terminals in the junction box, the junction box from the extension of the spindle is located on the right side of the base)Altitude: no more than 1000mThis type of motor is suitable for use in environments where the ambient air temperature does not exceed 40 ° C and there is no serious dust, the minimum ambient air temperature is -15 ° C, and there is no corrosive and explosive gas in the air (which can also be made into a damp heat or high-altitude motor).The high-quality slip ring motor is a sliding wrap-around three-phase asynchronous motor that can increase the starting torque at a small starting current. The motor is suitable for applications where the capacity of the feeder line is insufficient to start the squirrel-cage rotor, the starting time is long, the starting is frequent, and the small-range speed regulation is required. This series of motors has the advantages of high efficiency, energy saving, low noise, low vibration, light weight, reliable performance, convenient installation and maintenance.Main process flow of the motorMotor stator: casing processing → punching press → iron core seating → coil making → weaving → dipping paint dryingElectronic rotor: blank shaft processing → iron core press installation → iron core cast aluminum → rotor string shaft → weave → dipping paint drying → dynamic balanceMotor assembly: stator rotor assembly → machine test → motor appearance coloring → packaging storageThe company insists on providing high-quality motor products and services to users, and has won high praise from many domestic and foreign customers.
