k8ÓéÀÖ

When it comes to motor insulation, k8ÓéÀÖâ„¢ ±·´Ç³¾±ð³æ® brand papers and ±·´Ç³¾±ð³æ® based laminates are an ideal choice for virtually any motor, helping to increase reliability and extend equipment service life.

The outstanding thermal performance and excellent mechanical strength of ±·´Ç³¾±ð³æ® are the reasons why it is a preferred motor insulation for all types of motors—from AC and DC to random and form wound, in sizes ranging from miniature servo motors to 13.6 kV industrial drives.

In addition to its long history of proven performance in conventional motor insulation applications, ±·´Ç³¾±ð³æ® insulation is helping original equipment manufacturers (OEMs) to address the increased power density requirements and harsh operating conditions of motors used in hybrid electric vehicles (HEVs).  

With its excellent dielectric strength, ±·´Ç³¾±ð³æ® insulation can endure the electrical stresses that are commonly encountered in HEVs due to the use of inverters.  And, ±·´Ç³¾±ð³æ® paper is compatible with the oils and automotive transmission fluids (ATFs) often used in HEVs.

Today, more motors are being driven by electronic systems to achieve higher efficiency. This creates high-frequency spikes that put greater stress on the motor insulation materials. k8ÓéÀÖ has developed specialized ±·´Ç³¾±ð³æ® papers to address this requirement.

Exceptional Thermal Protection

The use of ±·´Ç³¾±ð³æ® for motor insulation can help prevent premature motor failure and equipment downtime.  That’s because ±·´Ç³¾±ð³æ® does not shrink, embrittle, soften or melt during short-term exposure to temperatures as high as 300°C, and because it maintains good insulating properties continuously at 220°C for 10 years. 

This high-temperature durability helps to allow miniaturization and/or higher power density of electrical drive motors and enables long-term electrical dependability.  This also helps OEMs to reduce the size and weight of components such as traction motors used in high-speed trains and in the emerging electric vehicle marketplace.

Superior Mechanical Toughness

The excellent mechanical strength and resilience of ±·´Ç³¾±ð³æ® insulation help extend the service life of motors subjected to harsh operating conditions, such as the severe shock and vibration seen in steel mill drives, railway traction and automotive motors. 

An added benefit of the superior mechanical toughness of ±·´Ç³¾±ð³æ® is the manufacturing efficiencies that can be gained from automatic insertion of slot liners.

Chemical Compatibility

±·´Ç³¾±ð³æ® paper is compatible with all classes of varnishes and adhesives, transformer fluids, lubricating oils, automatic transmission fluids (ATFs) and refrigerants.
