Building the winding architecture – Easy mode – Main principles



Building the winding architecture - Easy mode
1 Selection of the Easy mode for building the winding architecture.
2 Selection of winding type.

Lap: The ends of one coil are connected to consecutive commutation segments (i.e., the commutator pitch absolute value is equal to 1 for simplex winding)

Wave: The ends of one coil are connected to commutator segment separated by an angular distance as close as two pole pitch as possible (for simplex winding)

3

Selection of the plex. The plex is a measure of how many commutator segments can touch a particular brush at the same time. The number of parallel paths in the machine circuit is directly proportional to its plex.

Even if there is not a theorical limitation to its value, for practical designs three plex are considered: simplex (plex=1), duplex (plex=2) and triplex (plex=3).

4

Selection of coil connection: Progressive or regressive

Progressive connection: Commutator segments are connected following the same direction as winding (i.e., commutator pitch is positive).

Regressive connection: Commutator segments are connected following opposite direction as winding (i.e., commutator pitch is negative).

Illustration of these two types of winding is given in next sections.
