Product Details
Dynamometer, as the key equipment of power mechanical performance testing, is widely used in the field of performance testing and research and development of automobiles, engines, motors, wind power generation, ship propulsion systems and various industrial power equipment. It can not only measure the output torque, speed, power and other key parameters, but also simulate the actual working conditions to evaluate the performance, efficiency, durability and emissions of the equipment.
Features: The absorbed mechanical energy is converted into electrical energy through the power electronic converter to feed back to the grid or for other purposes to achieve energy recovery. It has the advantages of high precision, wide speed range and fast dynamic response.
Application: It is widely used in the testing of automobile engines, electric motors, gearboxes, hybrid power systems, etc., as well as the performance evaluation of electric vehicle drive systems.
Each dynamometer has its own unique application scenarios and technical advantages, the choice should be based on the type of object under test, power range, test needs and budget and other factors. The correct choice can not only improve the test efficiency, but also ensure the accuracy and reliability of the test results.
Electric Power Dynamometer
1. Uses a frequency converter to control the load, with superior control performance, capable of constant speed or constant torque control.
2. Can operate in four quadrants, functioning as both a generator (load) and a motor (drive). It can provide a certain load from zero speed to maximum speed, with load characteristics: constant torque from zero speed to rated speed, and constant power from rated speed to a certain speed.
3. Maintenance-free and energy-saving.
4. Suitable for testing characteristic curves of various motors, temperature rise, and simulation life tests, especially for automotive drive motors, permanent magnet synchronous motors, variable frequency motors, and ISG motors.
Suspended Electric Power Dynamometer
1. Guangzhong Electric has specially launched the suspended electric power dynamometer based on the ordinary electric power dynamometer (servo motor + torque sensor structure).
2. The suspended electric power dynamometer consists of an AC asynchronous servo motor (permanent magnet synchronous motor), encoder, tension and compression sensors, signal processing circuit, and base, using a motor stator suspension structure to measure load torque through reaction force.
3. The suspended electric power dynamometer has a compact structure, with the tested motor and load motor directly connected, fewer intermediate transmission components, and no rotating torque speed sensors, resulting in low connection loss, low rotational inertia, and low vibration noise. Additionally, by converting rotating torque into stationary torque for measurement, it greatly improves measurement accuracy.
