The energy efficiency standards for the direct-on-line motors are more limiting and harder to achieve. That is why is needed to think different ways to achieve the limits. The directon-line Synchronous Reluctance Machine is one solution for this need.
The base for the direct-on-line Synchronous Reluctance Machine comes from ordinary Synchronous Reluctance Machine. The difference is that the air barriers of the rotor are filled with the aluminium. This helps and increases the starting capabilities of the motor. It might also weaken the motor properties in the continuous mode if this is not taken into account in the design.
This master thesis focuses on the starting capabilities of the direct-on-line Synchronous Reluctance Machine with different voltages, loads and inertias. First is investigated the history and the structure of the direct-on-line Synchronous Reluctance Machine. Then the needs of different standards are show, in this the focus is in the starting properties and energy efficiency. In the laboratory is made different starting test to find the starting properties of the direct-on-line Synchronous Reluctance Machine. Also the energy efficiency of the tested motor is tested.
From the test results we can get valuable information about the starting capabilities and properties of the direct-on-line Synchronous Reluctance Machine. With help of this information can be estimated the starting successfulness with different loads, inertias and voltages. The soft starter tests gave good information about starting properties with help of it. With the help of the results from the test is made few equations which gives following results: starting torque with different voltages, starting current with different voltages and pull-in torque with different voltages. The energy efficiency of the tested motor were good, it were above energy efficiency class IE3. Also, reached out start-up successfulness with different combinations of moment of inertia and voltages.
