Application of NMN insulation material in motor

NMN insulation material usually consists of three layers: a layer of polyester film in the middle (also said to be made of polyimide film) and Nomex paper on both sides. Both Mylar and polyimide films have good dielectric strength and heat resistance, while Nomex paper is known for its excellent high temperature resistance, flame retardant and mechanical toughness. The close combination of these three layers of materials makes NMN excellent in both electrical and mechanical properties.

Application of NMN insulation material in motor

Slot, slot cover and interphase insulation: NMN insulation paper is mainly used for slot, slot cover and interphase insulation of low-voltage motors. These areas are prone to electrical breakdown and short circuit in the motor, so the use of NMN insulation paper can effectively improve the insulation performance and safety of the motor.

Interlayer insulation: In addition to intergroove, cover and interphase insulation for motors, NMN insulation paper can also be used for interlayer insulation for transformers or other electrical appliances. This helps to ensure that an appropriate insulation distance is maintained between the electrical components inside the electrical equipment, preventing the occurrence of electrical breakdown and short circuit.

Improve the stability and reliability of the motor: Because NMN insulation paper has outstanding mechanical and electrical properties, the use of it can improve the stability and reliability of the motor. This helps to ensure that the motor does not experience problems such as insulation failure or electrical failure during long periods of operation.

Application advantages of NMN insulation materials

Improve the insulation performance of the motor: NMN insulation paper has a high insulation strength and heat resistance grade, which can effectively improve the insulation performance of the motor.

Enhance the durability of the motor: Due to its excellent mechanical and electrical properties, NMN insulation paper can enhance the durability of the motor and extend the service life of the motor.

Simplify the production process of the motor: The smooth appearance of NMN insulation paper helps to use equipment such as automatic downlines in the production process of the motor, thus simplifying the production process and improving production efficiency.

NMN Insulation paper Transportation and storage

This motor insulation paper should be stored in a dry, ventilated, clean room environment away from moisture.

Transportation and storage time should pay attention to fire, moisture, pressure, and sun protection.

The storage period is 12 months at room temperature, and can still be used after passing the storage period according to the technical requirements.

The main characteristics of NMN insulation materials

1.Heat resistance: The heat resistance grade of NMN insulation materials is usually F (155 ° C), and some products can even reach H (180 ° C) or higher. This means that it can maintain stable insulation performance in high temperature environments and will not lose insulation due to temperature rise.

2.Mechanical properties: The material has high strength and excellent edge tear resistance and can withstand large mechanical stresses without breaking. This makes it able to withstand a variety of complex mechanical stresses in the manufacture of electrical equipment such as motors and transformers to ensure the stable operation of the equipment.

3.Electrical properties: NMN insulation materials have excellent electrical strength and can maintain insulation properties under high voltage. Its smooth surface helps to achieve trouble-free operation during the production process and ensures the safe operation of electrical equipment.

4.Flame retardant properties: Nomex paper, as an important part of NMN insulation materials, has excellent flame retardant properties. When in contact with the flame, the NMN insulation material can resist burning or prevent further burning when leaving the flame, thus effectively preventing the occurrence of fire accidents.

5.Corrosion resistance: NMN insulation materials also have good corrosion resistance and can resist the erosion of various corrosive substances to ensure the stable operation of electrical equipment in harsh environments.
