Abstract
The purpose of the proposed research is the development of permanent magnet brushless DC motors. The developed motors will be primarily designed for the drive of gas burners and, generally, for the drive of other special devices. Two development concepts will be treated in the investigation.
In the first case, the inner-rotor permanent magnet brushless DC motor with output power up to 700 W will be analysed and designed. In the second case, the outer-rotor permanent magnet brushless DC motor with output power up to 70 W will be analysed and designed.
In respect to certain construction particularities and restrictions, the planned field of use, anticipated mechanical load and the required corrosive and hardiness properties of the materials, of crucial importance will be the proper selection of magnetic steel material together with the appropriate selection of winding design and permanent magnet material of motor.
The direct and indirect influence of different motor cross-section shapes, different winding designs and different material and geometrical properties of permanent magnet materials on static and dynamic motor characteristics will have to be parametrically dissected and examined closely with the use of analytical and numerical methods of work.
In the final phase it will be necessary to find an optimal solution for both motor constructions (inner-rotor type and outer-rotor type) in respect to the desired price category and required motor characteristics.
In the development concept of both motor types (inner-rotor type and outer-rotor type) the influence of Hall-sensors placement on working of control electronic unit will be included in the analysis.
