The UNICO E-Axle Dyno Drive is a leading-edge testing system combining different drive elements with a common DC power source. It can handle power from 50 kW to 1000 kW, even more, if needed. This system is designed to work with common and advanced motor types, offering efficient and comprehensive testing capabilities. Whether you need steady, quick, or dynamic testing, this system can do it all and works well with any control system. It comes in designs that can be air or water-cooled and includes many safety features for reliable and safe operations.
Minimize energy use while maintaining high performance
Saves space and enhances ease of integration into existing setups
Delivers versatile application potential from low to high torque
Accommodates a broad spectrum of DC voltages, enhancing compatibility
Features flexible settings for remote voltage and current measurements, reducing infrastructure costs
Lowers power disturbances and enhances quality
UNICO’s E-Axle Dyno Drives’ feature a modular inverter design that fully regenerates energy back to the three-phase power grid. This system includes a proprietary digital current regulator and a cuttingedge controller that facilitates seamless operation of various AC dynamometer motors—including Asynchronous Induction, Synchronous Permanent Magnet, and Internal Permanent Magnet motors— without the need for the traditional current-loop setup.
Our drives utilize IGBTs with a switching frequency of up to 30kHz, delivering the necessary performance to operate high-speed dynamometer motors. This capability ensures accurate matching of the high-speed requirements of the E-Motor under test.
The drives deliver remarkable speed and torque responses, with acceleration rates reaching 300,000 rpm per second, enabling precise testing under conditions that simulate realistic load resistance for various applications such as aggressive launch control, motoring, hill climbs, and diverse throttle settings. For Noise, Vibration, and Harshness (NVH) testing, the ultra-quiet operation mode supported by dual current regulators proves ideal, suitable for use in both anechoic and hemi-anechoic test cells.
Enhance the development and testing of your electric vehicle propulsion systems with UNICO’s E-Axle Dyno Drive, designed to simulate resistance accurately. This advanced tool allows for comprehensive evaluation and optimization of EV systems under controlled conditions, ensuring your products meet the highest standards of performance and reliability.
