synchronous motor. The synchronous motor has one 3-phase winding in the stator. The current in each phase is controlled by a 12-pulse cycloconverter. The 12-pulse configuration is obtained by the wye-delta connection in the secondary winding of the power transformers and reduces the low frequency current harmonics in the load and at the input ...

Abstract: In the process of selecting a suitable motor for a cement mill, there are several issues to consider that, for the purpose of analysis, can be grouped into two distinct categories. The first category is the technical analysis, which is based on engineering considerations that evaluate the merits of either a synchronous or a slip-ring induction …
