World-class solar-powered race car

Solar Team Twente is building one of the fastest solar race cars in the world. Such solar-powered race cars are all about speed, maximized by high efficiency of the drive system. To achieve this goal, we have partnered with Solar Team Twente to develop a gallium nitride-based motor inverter based on our VIPER platform.

Kendrion 3T has proudly served as a sponsor and technology partner of Solar Team Twente since 2006, continuously enhancing the Motor Controller Unit (MCU) to propel Solar Team Twente toward greater speed and efficiency.

Battery-powered rescue tools

In collaboration with a client, Kendrion 3T faced the exciting task of finding a cost-efficient way to power and control their new product series. It required seamless functioning between hydraulic and battery-powered components and a demanding control algorithm for the hydraulic pump. Furthermore, the tool had to be robust and reliable, operate efficiently, be submersible, and be able to withstand high peak currents generated by mechanical forces. 

Based on this, Kendrion 3T developed a reliable solution for a BLDC motor, including robust electronics capable of operating underwater.

Forestry & agricultural equipment

Designed for rugged outdoor environments, VIPER powers the electrification of modern forestry and agricultural equipment. From chainsaws and wood splitters to winches, sprayers and battery-powered hydraulic systems, it delivers efficient and reliable motor control for demanding applications.

Optimized for 12–48V systems, VIPER maximizes battery runtime while providing high torque and stable performance under dynamic loads. Its robust, vibration-resistant design ensures consistent operation in wet, dirty, and extreme temperature conditions – making it the ideal solution for heavy-duty field use.
