Draw the front elevation left half in section, section plan of a 3-phase transformer with the dimensions given below, scale 1:4 full size: jimhendershot.com tooth the same as Figure I-A. Figure I-C is an (8) pole, (18) slot motor with (3) phases and a (2) slot coil winding pitch. Figure I-D is a common brushless configuration for (3) phase motors with (4) poles, (12) slots and a (3) slot coil winding pitch. Figures I-E and I-F are brushless designs with (6) pole … Emetor - Glossary - Winding factor The winding factor for a specific winding expresses the ratio of flux linked by that winding compared to flux that would have been linked by a single-layer full-pitch non-skewed integer-slot winding with the same number of turns and one single slot per pole per phase. The torque of an electric motor is proportional to the fundamental winding factor. (PDF) A new 4/6 pole-changing double layer winding for
