The application of methyl silicone oil (dimethyl silicone oil) in the field of motor manufacturing is mainly based on its excellent insulation, thermal stability and chemical inertia. The specific application scenarios and technical advantages are as follows:
As an electrically insulating medium
Insulating impregnant
Methyl silicone oil is widely used in the impregnation treatment of motors, transformers, capacitors and electronic instruments. Its characteristics include: high temperature resistance: can work stably from -50℃ to 200℃ for a long time and stable manner, adapting to the high temperature environment during motor operation.
Excellent dielectric performance: small dielectric loss, resistance to arc and corona, and can maintain insulation performance especially under high voltage or high frequency conditions.
Moisture-proof and dust-proof: A waterproof and dust-proof film is formed on the surface of the equipment to reduce the environment's erosion of internal circuits.
Replace traditional insulating oil
Compared with mineral oil, methyl silicone oil has a higher flash point and ignition point (≥315℃), which greatly improves equipment safety and is especially suitable for motor systems in flammable environments.
Shock absorption and damping materials
Precision instrument protection
Methyl silicone oil, as a liquid damping material, can effectively absorb mechanical vibrations and stabilize instrument readings in components with high motor vibration. Its viscosity is less affected by temperature and is suitable for extreme temperature scenarios such as aircraft and automotive motors.
Application of liquid springs
Used in high impact scenarios such as aircraft landing gear, it absorbs energy through compressibility to protect the motor structure.
High temperature lubrication and heat dissipation
lubricant
As a high-temperature lubricant (such as bearings and gears), methyl silicone oil has more than 20 times better shear resistance than mineral oil, reducing friction and wear and extending component life.
Heat carrier
As a heat conduction medium in the motor cooling system, its high thermal stability is utilized to achieve efficient heat dissipation and avoid local overheating.
Surface protection and sealing
Anti mold and anti oxidation coating
Coating the motor casing or internal components (after heat treatment at 250-300 ℃) to form a waterproof, anti mold, and insulating protective film, significantly improving weather resistance.
Sealing material additive
Enhance the flexibility of the seals to prevent lubricant leakage and resist chemical corrosion.
Other auxiliary applications
Defoamer: add a small amount (10-100ppm) in motor coolant or lubricating oil to avoid foam affecting heat dissipation efficiency.
Release agent: used for molding and processing plastic or rubber components of motors to ensure a smooth surface.
Through the above applications, methyl silicone oil significantly improves the reliability, lifespan, and safety performance of motors, especially suitable for high demand fields such as aerospace and new energy vehicles.
