The work, headed by Ph.D. Tadeusz Daszczyński, was done by team consisting of Ph.D. Jan Szczypior and MSc. Rafał Jakubowski.
Research and development works included:
- Analysis of several variants of the stator structure, justification for the selection of one variant of the stator structure;
- Performing the analysis of several variants of the rotor structure with nested and surface magnets, justification for the selection of one variant of the rotor structure;
- Performing design calculations on the basis of a circumferential model of several machine variants with different number of pole pairs, different number of slots and several efficiency values – selection of the number of stator slots, number of poles and efficiency values;
- Performing a series of design calculations based on the field model of the machine – determining the shape of the stator teeth and the shape of the rotor magnets;
- Final design of the stator winding determining the number of turns, the number of parallel conductors and the standard diameter of the conductor;
- Development of technical documentation of individual details of the generator and auxiliary equipment;
- Development of technological documentation – a detailed description of the method of making individual parts: stator core, rotor core, mounting magnets in the rotor of elements and the complete stator winding;
- Agreeing the details of individual parts with the contractor, supervising the implementation of the elements and the complete prototype of the machine;
- Performing the prototype tests, confronting the assumed and measured values of operating parameters.
The result of the work is a generator prototype based on a three-phase, synchronous electric machine with magnetoelectric excitation with operating parameters: power – 2 kW, rotational speed – 375 rpm, effective line voltage 60 V.www.ien.pw.edu.pl
