Ignition coil primary winding. Current flow through the coil produces an electromagnetic field, which is used to induce a highvoltage in the secondary coil.
点火线圈初级绕组。电流通过线圈，产生一个电磁场，用来在次级线圈中产生高电压。

More turns of winding is needed to produce enough voltage because the DPMG rotates at low speed, but the armature reaction is high at same time.
In this paper a computational method for determining the temperature distribution in the highvoltageWinding of dry epoxy resin distribution power transformer is suggested.
