Servo machine test stand for 1kW machines incl. software ActiveServo (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 synchronization to be carried out.

The controller has the following features:

• Dynamic and static four-quadrant operation
• 13 selectable operating modes/machine models (torque control, speed control, flywheel, lifting drive, roller/calander, fan, pump, compressor, winding gear, arbitrarily defined time-dependent load, manual and automated network synchronization)
• Testing for the presence of a shaft cover.
• Disconnection of the supply voltage of the motor under test in the absence of shaft cover
• Interface for reading electronic nameplates EDD of the machines under test
• Integrated galvanically isolated amplifier for voltage and current measurement
• 5" colour touch display
• Four-quadrant monitor
• Isolated USB interface
• Thermal monitoring of the machine under test
• Connection voltage: 400 V, 45...65 Hz
• Maximum power output: 10 kVA
• Dimensions: 297 x 460 x 420 mm (HxWxD)
• Weight: 16.5 kg

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: 4000 rpm
• Maximum torque 30 Nm
• Temperature monitoring: continuous temperature sensor (PT1000)
• Resolver resolution: 65536 pulses/revolution
• Dimensions: 275 x 210 x 210 mm (WxHxD)
• Weight: 9 kg

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

Features:

• 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)
• Configuration of settings via electronic nameplates EDD of the DUTs
• 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
