该方法还包括：将屏蔽绕组的匝数增大至大于所计算出的匝数；
The method further includes: increasing the number of turns for the shield winding;
由于直驱式风力发电机转速较低，定子绕组需要有较多的匝数以输出足够高的电压，因而绕组负载电流的去磁反应较大；
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.
根据等效整距集中绕组与实际绕组产生相等基波磁动势的原则，给出了实际定子绕组与转子绕组的总有效匝数表达式。
Based on the principle that an equivalent full-pitch, concentrated winding gives the same fundamental MMF as the actual one, the effective number of turns of the equivalent winding is obtained.
