Представлена 3D модель високомоментного тихохідного двигуна з ротором, що котиться, (ДРК) з аксіальним магнітним потоком, а також показані результати його експериментального дослідження при різних схемах включення котушок обмотки статора, і з використанням шихтованого і масивного осердя роторів. Наведено схему випробувальної установки, побудовано і порівняно механічні характеристики для кожного з варіантів включення котушок обмотки статора.
Purpose. Choice of optimal constructive and technological solutions to create new designs of motors with a rolling rotor (MRR). Methodology. Modeling of electro-magnetic processes, which appeared in MRR, followed by an experimental research. Results. The optimal winding circuit of the MRR is a circuit of the coils through all 6 diodes. In this connection, the mechanical characteristics MRR-50-6 – is the most rigid. Using the rotor core lamination increases the power efficiency up to 20-30%, compared with the massive rotor core, but it is much worse power factor (by 25-35%). In addition, we should take the complication of manufacturing each rotor into account. Originality. MRR is a non-standard machine in which the rotor rolls over the stator surface with has guaranteed eccentricity. Therefore, the process of transferring the torque from the rotor to the shaft is a complex engineering problem, which was successfully implemented during the research. Practical value. A 3D model of a high-torque low-speed MRR with an axial magnetic flux is presented, and the results of its experimental research are shown for various schemes of connection of the stator coils, using a laminated and massive rotor core. The scheme of the test set is given, the mechanical characteristics for each variants of coils connection are plotted and compared.
