3. SSCD200-1000/3300 200kW Motor Performance Electric Dynamometer Bench System Core Advantages
- Precise adaptation for medium and high power
With a rated power of 200kW and a torque range of 0-1910Nm, and a
maximum speed of 3300rpm, it covers the full-condition testing
needs of medium and large power motors; the constant power range of
1000-3000rpm accurately matches the operating characteristics of
commercial vehicle drive motors and industrial medium and large
motors, avoiding test blind spots.
- Multidimensional measurement accuracy assurance
Equipped with an HBM 0.2% FS high-precision torque flange, combined
with a Seelong WT5006 power analyzer (0.03% basic accuracy) and an
Advantech multi-channel data acquisition system, it achieves
synchronous and accurate acquisition of key parameters such as
torque, power, temperature, and vibration, with a data error of
≤0.5%, meeting the stringent requirements for testing accuracy in
the national standard GB/T 18488-2024.
The battery simulator supports a wide voltage output of 24-1200V,
adapting to the power supply requirements of medium and high power
motors from 48V low voltage to 800V high voltage; the ABB frequency
converter system is compatible with a wide voltage input of
380V±10%, maintaining stable operation even under voltage
fluctuation scenarios, and can adapt to different regional power
grid environments.
- Flexible configuration and stable operation
The system encompasses core modules such as measurement and
control, data acquisition, and power analysis. Optional components
such as couplings and motor brackets can be combined as needed. The
motor bracket has an adjustment range of 200-500mm to accommodate
motors of different specifications. The combination of HT300 cast
iron plate and spring shock absorber effectively reduces vibration
interference during testing and ensures long-term stable operation
of the equipment.
