The tests are carried out with industrially manufactured machines. All test machines have a special base for connection to the Machine Test System 0.3. With the Machine Test CASSY all measured values of the AC machines are recorded. The measured values

Motors with slip-ring rotors (wound rotor motors) represent a type of asynchronous machine. Unlike squirrel cage rotor machines, a slip-ring rotor is in the form of a three-phase winding attached to a slip-ring and accessible from the outside via brush

All functions of the Machine Test CASSY 0.3 can be operated quickly and directly via the display, the rotary wheel and the buttons on the unit. All settings and measurement results can be saved on the unit and quickly called up again later or simply do

The individual equipment is equally suitable for student experiments in the laboratory with low voltage (230 / 400 V three-phase current) and - with a mobile trainer - for teacher demonstration in the classroom. The experiments are carried out according t

The target group is made up of commercial apprentices and students of electrical machine construction. The course offers experiments at an intermediate level and also allows for the necessary insight into machine behaviour for scientific interpretation at

In the following configurations there are further extended experiments with the slip-ring motor:
