Наш electric drive and powertrain universal dynamometers are designed to handle a variety of testing needs, including EMC/EMI testing for high-speed motors, low-speed high-torque powertrains, and low-speed high-torque motors. This versatile system is perfect for evaluating the full range of electric drive systems under real-world conditions.
The system utilizes a medium-speed high-torque dynamometer that connects to a dual-output shaft gearbox. Through gear transmission, the high-speed shaft can be increased to higher speeds, while the low-speed shaft is directly powered by the dynamometer. This flexible configuration allows for testing both high-speed, low-torque и low-speed, high-torque electric drive systems.
Однако, due to the introduction of a high-speed gearbox, the mounting surface area for the motor will be larger, and the reflecting surface area will also increase. This can lead to a slight impact on measurement uncertainty. To mitigate these effects, our product is equipped with several key design features to ensure optimal performance and accuracy:
Oil and Gas Absorption Device: The high-speed gearbox is equipped with a device that prevents oil and gas from volatilizing into the anechoic chamber, maintaining the integrity of the testing environment.
Medium-Speed High-Torque Dynamometer: This dynamometer reduces the gearbox’s transmission ratio, lowers the center distance, and minimizes the gearbox’s cross-sectional area. This design effectively reduces the impact on measurement uncertainty, ensuring more precise test results.
Lubrication System with Power-Failure Protection: The gearbox’s lubrication system is equipped with a mechanism that continues to supply oil for at least 5 minutes after a power failure, preventing damage to the gearbox due to oil cutoff during testing.
Constant Temperature Lubrication System: The system features a constant temperature device that ensures the oil inlet temperature remains stable. This helps minimize the influence of lubricating oil viscosity on transmission efficiency and eliminates errors in torque measurement caused by fluctuations in transmission efficiency.
These thoughtful design elements ensure that our powertrain testing system delivers accurate and reliable results, even in complex testing scenarios. The system is highly adaptable and capable of addressing a wide variety of electric drive and powertrain testing requirements
