The selection of insulation class is critical to the life of the motor. If the upper temperature limit of the insulation material is exceeded the life of the insulation will be reduced at illustrated below. * SF - NEMA Service Factor Insulation Life and Temperature The table below compares the IEC temperature rise ratings, with the NEMA specification: Insulation Motor winding machine, Armature Winding Machine, Stator Winding Machine, Needle. This gives a 25 o C margin – can be used for high ambient temperatures for example. The composite insulating material paper has good dielectric properties. Dmd Laminated Electric Motor Winding Insulation Paper is made of a layer of polyester film coated with adhesive and polyester fiber non-woven composite, through calendering and made of composite insulation material products, referred to as DMD, which is mainly divided into F and B grade two kinds of insulation paper. Tip: specify a class ‘F’ insulation, but a class ‘B’ temperature rise. Laminated Electric Motor Winding Insulation Paper DMD. Note: motors are typically rated for class 'B' or 'F' insulation If a motor is subjected to an ambient temperature higher than 40 o C, it must normally be de-rated or a higher insulation class of material used. The correct insulation of the winding of a motor is determined by both the temperature rise in the motor and the temperature of the ambient air. Each class is given a designation that corresponds to the upper temperature limit of the insulating material when used under normal operating conditions. Our products mainly used for transformer and electrical motor, we produces insulation paper, insulation board, insulation tape,insulation film and also sales PTFE FR4 PA6 and cable wire.IEC 60085 ‘Electrical insulation - Thermal evaluation and designation ’ divides insulation into classes.
Most electric motors are made up of stacked layers of stamped steel that create the motors stationary core. In our case, insulation is the paper product that separates the copper from the steel in an electric motor. Motor Stator Slot Insulation Induction Motor Winding Machine. Insulation is used in various places, from pink insulation in a new homes walls to the insulation jacket on lead cable. Motor Winding Equipment Servo Motor Stator Slot Insulation for Different Slots.
Main products are manufactured on international standard. Insulation Paper Inserting Machine Slot Bottom Insulation / Suitable exclusively for large and medium-size motors. the insulation to wear off the wire and produce a grounded motor winding. Our manufacturing technique is leading in this field and well known in the world. Now there are more than 20 product facilities, and 105 staff, including 5 senior technical, 20 intermediate technical. FIGURE 9-62 Insulated paper placed between the windings and the stator frame. The maximum winding temperature increases by 25° C with each step up in insulation class, as shown below. Till now we import and export to many contries, such as United Kingdom, Germany, France, Ukrain, Bulgaria, Italy, India, Pakistan, Bangladesh, Korea, Brzil and so on. The NEMA insulation classes currently in use are A, B, F, and H, although newer motors are rarely built with class A insulation, which has a maximum winding temperature of 105° C. It is located in Xuchang City, Henan Province, China. From 2010 year old our company begin deal international trade, based on the original business.
