Servo machine test bench for 1kW machines incl. ActiveServo software(D,GB,F,E)

The servo-machine test bench is a complete testing system for examining electrical machines and drives. It consists of a digital controller, a brake and the ActiveServo software. The system combines state-of-the-art technology with ease of operation.
The system also allows manual and automated synchronisation to be carried out.

The controller has the following features:

  • Dynamic and static four-quadrant operation

  • 10 selectable operating modes/machine models (torque control, speed control, flywheel, lifting drive, roller/calander, fan, compressor, winding gear, arbitrarily defined time-dependent load, manual and automated network synchronization)

  • Integrated galvanically isolated amplifier for voltage and current measurement

  • Speed and torque displays

  • Four-quadrant monitor

  • USB interface

  • Thermal monitoring of the machine under test

  • Testing for the presence of a shaft cover.

  • Connection voltage: 400V, 50Hz

  • Maximum power output: 10kVA

  • Dimensions: 297 x 460 x 420mm (HxWxD)

  • Weight: 14.3kg


The brake is self-cooled asynchronous servo-brake with resolver.

The motor and sensor leads are connected via polarity-safe plugs. The machine has thermal monitoring and, in conjunction with the controller, it constitutes a driving and braking system that is free of drift and requires no calibration.

  • Maximum speed: 4000rpm

  • Maximum torque 30Nm

  • Temperature monitoring: continuous temperature sensor (KTY)

  • Resolver resolution: 65536 pulses/revolution

  • Dimensions: 275 x 210 x 210mm (WxHxD)

  • Weight: 6kg


ActiveServo is a program for recording characteristics of machines and for determining dynamic and static operating points. It emulates seven different loads (flywheel, pump, calander, lifting drive, compressor, winding gear, arbitrarily configurable time-dependent load) for which the parameters can be individually configured.


  • Measurement, calculation and display of mechanical and electrical variables

  • (Speed, torque, mechanical power output, current, voltage, active, apparent and reactive power, efficiency, power factor)

  • Simultaneous display of measured and calculated values (e.g. instant display of efficiency)

  • Measurement of voltage and current (including RMS values even for non-sinusoidal waveforms)

  • Speed or torque-controlled operation

  • Recording of variables over time

  • Programming of limiting values of speed or torque to prevent inappropriate loading of the machine under test.

  • Operation in all four quadrants (display of generated torque)

  • Arbitrarily defined ramp functions for PC-controlled load experiments

  • Display of characteristics from several experiments to better illustrate the effect of parameter changes

  • Export of graphics and measurements
