SMYC 250--315KW 4500rpm 0.05%FS Low Moment of Inertia and High Torque Dynamometer




SMYC series dynamometer is the load of power mechanical power test. The standard SMYC series dynamometer consists of an AC motor, a set of torque and speed measurement sensors, base and flange connected with power machinery.

The dynamometer is equipped with a set of four quadrant ACS AC frequency conversion speed regulation and distribution system, and a dynamometer measurement and control instrument, which can complete the dynamic test of the test piece.





  • Good loading characteristics: constant torque below rated speed, constant power above rated speed.
  • The loading stability is good.
  • Full function: it can operate in four quadrants, so the test bench can simulate two driving conditions of the vehicle, namely traction driving mode and sliding driving mode, and the two working conditions can be quickly converted.
  • Two control modes of constant torque and constant speed can be switched arbitrarily.
  • Alarm function is complete: the controller has over-current, over-voltage, phase loss, under voltage protection alarm functions.



Technical Features


  • Speed measurement accuracy: ± 0.1 / min,
  • Torque measurement accuracy: ± 0.05% FS
  • Speed control accuracy: ± 1r/ min (frequency converter should be equipped)
  • Torque control accuracy: ± 0.2% FS (frequency converter should be equipped)
  • Dynamic response speed: < 5ms
  • Frequency conversion control mode: DTC direct torque control (should be equipped with frequency converter)
