Application and Purpose:
 
 
The motor coil must be impregnated with insulating varnish and its adjacent parts,
 
Let the conductor wire, slot insulation isolation parts whole compacted and immerged with
 
insulating resin coating become strong overall density.
 
The following purpose can be achieved through the insulation treatment:
 
 
1. To improve the moisture resistance of motor insulation
 
Any insulating material is more or less absorbing moisture in moist air. Such as Electrotechnical insulation
 
material paper DMD,PMP,Polyester, the moisture in the air is easily penetrated into the insulation material
 
along the capillary, thus the performance of the insulating material decreases significantly. The insulation
 
treatment will make the surface of the windings and coils form a smooth, pinless film or insulation seal
 
layer, which will greatly reduce the invasion of moisture and improve the moistureproof performance of the
 
motor.
 
 
2. Improve the heat resistance of motor insulation
 
Motor insulation materials in an insulating impregnating varnish before the material after heating the
 
internal decomposition of gas water molecules of low molecular substances, accompanied by oxidation,
 
changes in material properties such as mechanical strength, moisture resistance, reduce the decline of
 
brittle materials, have electrical properties such as insulation resistance and breakdown voltage
 
decreased, this phenomenon known as the aging of insulation materials, insulation insulation contact area
 
but after the treatment of material and air is greatly reduced, the rate of oxidation is greatly reduced, in
 
the same service life, the use of the temperature of the motor can be improved. Therefore, the heat
 
resistance of the motor insulation is improved.
 
 
3. Improve the thermal conductivity of the motor
 
The electrical insulation layer of air gap large, while the thermal conductivity of the air gap is low, the air
 
gap is filled with dipping paint, varnish and perfusion ratio due to thermal conductivity of air gap, so the
 
electrical winding motor and a corresponding increase in the conduction of heat, will greatly reduce the
 
motor temperature rise. The experimental data show that the temperature rise can be reduced by 10-
 
20%.
 
 
4. Improve electrical and mechanical properties of motor insulation
 
The motor winding coil and the insulation treatment, winding and Core Bond into a solid whole film will void
 
windings and the notch is full, the insulating layer is formed in a certain thickness of winding end of the
 
head, there is no gap inside the water is not easy to enter, so the insulation resistance and breakdown
 
voltage are improved, and at the same time winding core non relative movement, have sufficient strength
 
to resist the external vibration and stress, and bear the motor assembly process of mechanical impact,
 
thus avoiding the mechanical action of damage.
 
The motor windings impregnated after winding insulation system and the core to form a solid whole
 
reduces the effects of mechanical vibration and electromagnetic force vibration generated by the motor
 
during operation, the reinforcement effect on the machine, avoid wire between the wire and the core or
 
tank wall due to vibration, friction and damage the insulation displacement loose structure. The organic
 
insulation material inside the motor not only improves heat resistance and electrical performance, but also
 
improves the mechanical strength of the insulation material itself after impregnation. Because the
 
insulating material is heated, the material will change, releasing gas, water and carbonaceous materials,
 
lose flexibility, but after impregnation, pyrolysis, under heat hydrolysis process can greatly retard
 
mechanical flexibility material to maintain long-term, while insulating paint formed by the paint film has
 
certain elasticity and adhesion in the hot state, the material between the binding force of strengthening,
 
forming a strong overall, greatly enhance the strength of the system.
 
 
5. Improve chemical corrosion resistance
 
The motor through the impregnation treatment, to prevent all kinds of insulation materials and solvent
 
around the motor and direct contact with corrosive chemicals, which can improve the stability of chemical
 
substances of the motor due to the insulating encapsulation, shut off from the world body contact, improve
 
the winding stability, selecting suitable varnish resin materials can make the winding insulation with anti
 
mildew, anti oil, anti corona, flame retardant performance.
 
 
 
Question and Answer:
1. After resin varnish trickling, I need 1 hour
 It's OK you set 1hour after resin varnish trickling , that time can be set accoding to your resin performance and working experience,
 The resin will gel and then curing, the time can be setted on cycle time 
 
2. Working station distribution one side or two?
WIND-ZDG76-120 working station 120pcs, two sides, so you can install 240pcs armatures
