Ductile Cast Iron Foot Valve with Strainer
 

The core of a series motor is divided into two iron cores. In specific applications, the stator windings can be wound on the two iron cores separately, then, the two iron cores are divided into a whole body. Thus, the space limitation in the winding process can be reduced. And the winding process of the stator winding is simplified. It is beneficial to improve the winding efficiency, then to improve the production efficiency of series motor.
