E 2.1.3.4 Maszyny z wirnikiem
Opis
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 interchangeable rotors consist of a stator and various replaceable rotors. An electrical machine in the 300 W power range only comes into existence when the stator and rotor are put together. The stator has a 4-pole three-phase winding to generate the machine flux, along with a drive-end cap and a terminal box. The stator housing is mounted on a base and can be directly connected to the Machine test system 0.3 (731 989USB). A secure connection between stator and rotor is achieved by means of star-grip bolts, which allow for rapid changing of the rotors. No tools are needed. The rotors are equipped with non-drive-end caps, fan, cover and some include slip-rings, brushes etc. In conjunction with the machine testing system, the model machines then exhibit the typical properties of both synchronous and asynchronous (induction) machines. A DC stator with the relevant rotor is also available.
Highlights
- Comparison of efficiencies and characteristics of machines with different rotors
- Simple assembly for rapid set-up and time-effective lab experiments
- Experiments on high-efficiency rotors
The equipment set is suitable both for student experiments in a lab using low voltage (400 V three-phase) and on a mobile trolley for demonstrations by teachers in a classroom. The experiment procedures are contained in a printed 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 of torque-speed characteristic
- Determination of nominal ratings for an electrical machine
- Comparison of efficiency for various machines
