Elektroniczne przetwarzanie energii - Jerzy Skwarczyński

The Electric Machines Laboratory concentrates its research efforts on:

1. Electrical machines diagnostics with an emphasis on induction engines. The Electric Machines department (Katedra Energoelektroniki i Automatyki Systemów Przetwarzania Energii) has outlined a diagnostics system for induction engines with the intention of analyzing the frequency of their acceleration currents. This allows for a non-invasive type of diagnostics of the stator as well as the rotor. The level of eccentricity of the rotor in regards to the stator. Diagnostics of large induction engines with power ratings above the 100 kW mark at Krakow's electrothermal plant were carried out using this system. The laboratory also performs studies focused on synchronized diagnostic machines and machines equipped with commutators, their methods of diagnosis along with the specific devices in use.

2. Design and optimalization of electrical machine constructions, primarily energy saving induction engines and perma magnet motors in accordance with E.U. standards. These optimized methods of design and conceptualization allows for efficent engines in line with even the highest efficiency standard of 4 (IE4).

3. The quality of electrical energy and its influence on the efficiency of machines and devices. The point of interest being the impact of power supply networks with a distorted voltage on electrical machines (engines, generators) directly connected to the network, as well as the impact of heavy electrical machines on electrical power systems.

4. The innovation of magnetically induced electrical machines along with their hybrid variations to create electrical engines and generators for electric or hybrid vehicles.

5. The effective exploitation of electrical machines along side unconventional sources of energy, more precisely electrical machines working in tandem with hydraulic or wind turbines. This includes configurations allowing for the most attainable efficiency.
