Description

The Machine Test CASSY is part of the machine test system for the analysis of electrical drives and the simulation of machine loads. Its compact size allows it to be used in an experiment frame or as a table top unit.

The Machine Test CASSY differs from its previous model in that it has an additional LAN connection.

In addition to the control unit for the Electrical Dynamometer (7732 990), it has a powerful measurement and analysis system with four isolated and potential-free measurement channels, each for simultaneous measurement of current and voltage, comparable to the Power Analyser CASSY (727 100).

The speed measurement is carried out via an optical sensor and gives an angular resolution of 0.1 °.

The torque is measured up to ±33 Nm with a resolution of 1x10-2 Nm. This can then also be calibrated with a reference weight of 2 kg.

The Machine Test CASSY can be used for the following experiments, among others:

  • Analysis of machines as a motor and as a generator
  • Behaviour to different load cases, e.g. flywheel mass, blower etc.
  • Behaviour of time variable load cases
  • Study of frequency converter with asynchronous machine, IMP machines
  • Starting with star-delta circuit, soft starter and frequency converter
  • Parametrisation of control units for soft starting or heavy starting with slip-ring rotor

Machine selection:

It is possible to comprehensively parametrise all available machines. This parametrisation is supported by intelligent menu guidance. Due to integrated recognition of machine types of new design this selection is eased.

Furthermore, machines from the existing inventory can also be integrated and individually parametrised. A switch-over of the safety loop between LD machines and e.g. machines of the brand "ELWE Technik" is easily possible.

The menu "Freely parametrisable" additionally allows the manual input of parameters of older machines, third-party machines or special machines e.g. for research purposes. Please contact our technical consultants.

Operating modes:

Testing of motors

The control during the testing of motors is either done by the measured speed or with the help of the measured torque.

  • Speed control: Manual, Automatic, Run-up characteristic, Load characteristic
  • Torque control: Manual, automatic dynamic unloading, automatic dynamic loading, automatic static according to IEC DIN VDE 60034-2-1 in 6 steps and additionally in 16 steps from 0% to 150%

Testing of generators

Electrical machines can be tested, monitored and analysed by the system as a generator in isolated operation - but also in mains operation.

Load simulation
