Description

The experiments are carried out with the industrial machine assembly kits.

Objectives

  • Protective measures and electrical safety
  • Recording machine characteristics
  • Set-up of various electrical machines

Machines with alternating rotors can be DC machines, induction machines and synchronous machines. Several alternating rotors and stators are available for assembling the machines. Only by assembling the stator and rotor does come to a working electrical machine of the 300 W class. The stator contains a shunt winding or a series winding, the A-bearing shield and the terminal box. The stator housing is mounted on a base and can be connected directly to the machine test system 0.3. The stator and rotor are securely connected by star grip tension bolts, which allow the rotor to be changed quickly. No tools are required for this. The rotors are equipped with B-bearing shield, fan wheel, cover and commutator, brushes, etc. Together with the machine test system, the characteristic curves of the machines can be traced back to the properties of the respective stator or rotor. Depending on the stator or rotor used, the model machine then shows the typical characteristics of the different machines. 

Highlights

  • Comparison of efficiencies and characteristics of machines with different stators and rotors
  • Simple assembly for rapid set-up and time-effective lab experiments

The equipment is equally suitable for student experiments in the laboratory with mains voltage (220 V direct current) and - with a mobile trainer - for teacher demonstrations 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.

Topics

  • Recording the torque-speed characteristic
  • Determination of the nominal operating values of electrical machines as a motor or as a generator
  • Comparison of the efficiencies of different machines as motor or as generator
  • Load characteristic in generator operation
  • No-load characteristic in generator operation
