Introduction of electric products

Power module for EV drive motor (EESM) ~ TPM ~

Estimated lifespan of 1 million km with TPM!

As an important part of EESM, our high-performance carbon brush for wire-wound field is It greatly contributes to higher performance, longer life, and maintenance-free motors. We are also focusing on developing compact brush holders that take advantage of the features of long-life carbon brushes, and by making brush holders lighter and more compact, we will contribute to improving the electricity consumption of EESM EV and downsizing the motor.

High performance earthing system ~TES~

Prevent galvanic corrosion and eliminate noise with TES!

As the inverters and motors of electric vehicles such as EVs become more sophisticated, the problems of electrolytic corrosion and radiated noise are becoming more and more important. TRIS has developed and adopted high-performance earthing brushes from the first-generation Nissan Leaf as countermeasures against radiated noise, and by applying these, we have developed high-performance earthing brushes that can be used in various environments and applications such as electrolytic corrosion, oil submersion, and small brushless motor applications. We are currently developing a performance earthing system.
