Description

Research into the maximum performance of hybrid vehicle traction has led to the development of high-speed and high-torque electric motors that require specially designed AC dynamometer.

Dyno Equip offers the AC dynamometer motor with outstanding maximum torque of 500Nm and speed up to 20,000rpm that is combined with inertia lower than 0.1kgm2 for high vehicle dynamic simulation. The AC dynamometer has been achieved through the development of a hybrid hydraulic bearing technology that enables high speeds, while reducing vibration to 2mm per second at 20,000rpm. The Dyno Equip AC dynamometer may replace the real one for drivetrain and gearbox testing.

The latest application of this range of AC dynamometer is in a modular transmission test bench for vibration analysis and conformity of production. The three-motor test bench (with one input AC dynamometer and two output AC dynamometers) features a quick release specimen pallet, enabling three types of test configurations with easy and quick installation. Traditional transmission dynamometer, as well as high-speed powertrain dynamometer and driveline dynamometer for electric vehicles, can be made. For electric vehicle driveline testing, AC dynamometer with ultra low motor rotor inertia of guarantees achievement of high dynamic performance.
