Product description:
The real-time dynamic control system of the high-speed motor test bench can realize the speed and torque control through the real-time controller and simulate the actual load. The main control system can communicate with the environmental chamber, power analyzer, cooling system, EUT, etc., and realize control. The data acquisition system collects signals from torque sensors, vibration sensors, temperature sensors, pressure sensors, and other sensors, and transmits them to the main control system at a high speed. The sensor data can be displayed, saved and processed in the software interface.
The recommended dynamometer parameters are as follows:
Motor test bench selection specifications
Select the dynamometer according to the characteristic curve of the motor to be tested. The dynamometer is generally controlled by a four-quadrant inverter and can work in electric or power generation. The system can be equipped with high and low temperature environment chamber, battery simulator or DC bidirectional power supply, low power Adjustable DC power supply, power analyzer, cooling system and other accessories. According to users’ requirements for noise, water-cooled dynamometer or air-cooled dynamometer can be selected,The recommended parameters are as follows:

Test bench bottom plate
High-speed coupling, including the test piece support of the protective cover
The main structure of the test bench
The mechanical structure of the test bench includes: test bench base, dynamometer installation base, bearing support, test piece installation tooling, locked-rotor mechanism, test piece connecting shaft, etc..
Test bench base
The base of the test bench adopts integral casting structure. The upper surface of the base is the assembly surface. After precision processing, four air spring shock absorbers are installed at the bottom of the base for shock isolation and shock absorption.
Ultra high speed gearbox
The ultra-high-speed gearbox adopts a two-stage power distribution gearbox with coaxial input and output shafts. The parameters are as follows:
As a key component of the ultra-high-speed gearbox system, the lubrication pumping station is extremely important. The pumping station is provided by the ultra-high-speed gearbox supplier at the same time, and joint adjustment is carried out before leaving the factory.Test piece torque measurement
The torque measurement of the test piece adopts a direct measurement method, instead of installing the torque speed sensor on the low-speed end to measure, avoiding the transmission loss of the high-speed gearbox into the measurement data of the test piece motor.
Test piece connection
In order to facilitate the user to test different specimens, to facilitate the replacement of the connection tooling, and to avoid the torsional vibration of the shaft system, a torque flange, a transitional spline flange, and a spline are installed between the output end of the bearing housing and the input shaft of the motor under test. axis.
