Here we briefly introduce my company's products.
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.
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
