CHN Stator And Rotor For Electric Motor

VENT SPACER

The fixed and rotor iron cores of large motor are divided into many overlapping segments, and the punch plate of spot welded ventilation channel steel is placed between the iron core segments, that is, the ventilation groove plate. Thus, the radial air duct of fixed and rotor iron cores is formed for heat dissipation and ventilation cooling of iron cores. The manufacturing quality of ventilation operation must meet the strength requirements to ensure that no collapse or collapse occurs after loading. At the same time, the spot stotor welding position of the ventilation channel steel on the punching plate should be accurate. After each section of iron core is pressed, the axial position of the ventilation channel steel should be in a straight line to ensure that the radial air duct does not distort and the axial linear transmission of the pressing force of the stator and rotor core.

TECHNOLOGY DISPLAY

With the development of motor manufacturing technology and the upgrading of manufacturing equipment, the manufacturing technology level of ventilation groove plate has also been greatly improved. At present, there are four kinds of manufacturing process of ventilation groove plate that have been mastered. Spot welding technology is generally applied to the manufacture of ventilating groove plates of various motor stators.Bump welding is a new technology which has been applied to manufacture some DC motor armature ventilation groove plates. The rivet welding process is generally used in the manufacture of DC motor rotor and armature vent groove plate. The riveting process has been used in the manufacture of turbine generator stator vent groove plate and exciter rotor vent groove plate.
