Point out the position of brushes. 10 Temperature Rise 6 4. The run winding is wound with a heavier gauge wire to reduce its resistance. Each of the winding sets can change the direction of current flow in its half of the coil sets by reconnecting the coil sets either in parallel or in series. In this winding for a two-pole motor, there are two coil sides per slot and each coil spans 180 degrees, mechanical as. Example: In a 4 pole generator having a 48 slot armature core, the number of slots per pole would be 48 ÷ 4, or 12 slots per pole. number of slots. That would allow you to calculate an approximate number of winding turns for each winding distribution alternative that you wish to consider. Armature Construction. So each slot angle= 180°/9 =20°. Pole pitch: It is defined as number of armature slots per pole. Usage of fractional slot concentrated windings (FSCWs) in electrical machines offers several advantages due to their simplicity and compactness.
