What does dc motor controller in the stator of stand

Dc motor controller is composed of stator and rotor of two parts, and this two parts is divided into many small parts. Today we are going to speak is stand part of the stator. Dc motor controller of the stator housing referred to as the base, can have two functions: one is can be carried out on the main pole and commutating pole and end cover is fixed, and plays a role of support and fixed the whole dc motor controller. 2 it is itself part of the magnetic circuit, can access between the magnetic pole, which has enough mechanical strength and good permeability performance. Above is the introduction to the base portion of the stator, hope to help everyone.
