Description

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 DC machines are recorded. The measured values can be shown directly on the built-in display as a single value, table of a measurement series or diagram. The measurements can be made without additional software. The power supply for the test machines comes from special laboratory supplies.

Objectives

  • Protective measures and electrical safety
  • Setting up electrical machines and putting them into operation
  • Use of starting circuits
  • Assessment of electrical machine characteristics

Universal motors are a kind of commutator machine for both DC and AC operation. This is achieved by additional lamination of the iron in the stator. Universal motors can also be called single-phase series-wound motors. They are in widespread use, for example, in household appliances and machine tools.

Highlights:

  • In order to protect against overheating, the stator windings of the test machines are equipped with temperature detectors.
  • In case of overheating, the machine testing system switches off the load of the test machine, thus a preserved air cooling. This prevents damage to the testing machines.
  • The test machines are equipped with an educationally designed terminal board with the winding configuration printed on it.
  • The ends of all the windings are led out at the terminal board at safety sockets (4 mm).
  • Computer-supported acquisition of measurement data provides for meaningful measurement results.
  • The arrangement of the 4 mm safety sockets corresponds to the standards for industrial machines.

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 downloaded.

In addition, the Machine Test CASSY 0.3 is fully controllable in real time via RJ45 Ethernet, W-LAN and USB-C interfaces.

These interfaces can be used by the following software:

  • CASSY Lab 2 for drives and energy systems,
  • MATLAB® and LabVIEW ™
  • Lab Docs Editor Advanced

The following integrated servers are available in the Machine Test CASSY 0.3 for the local media connection of at least four end devices simultaneously.

For more details, see product data 7731900 or 7731901 Machine Test CASSY 0.3

The individual equipment is equally suitable for student experiments in the laboratory with low voltage (220 V DC) and - with a mobile trainer - for teacher demonstration in the classroom. The experiments are carried out according to the manual.

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 undergraduate level. The media connection makes the experiments suitable for demonstration in the classroom or a lecture hall.

In the following configurations there are further extended experiments with DC machines:

  • E2.2.3.1 Universal motor AC

Topics

  • Connection and operation of universal machines in a DC power supply network
  • Reversing direction of rotation
  • Measurement of efficiency
  • Armature reaction and commutation
  • Characteristics of motors
