In the structural design of dc motor controller is divided into two parts, the stator and rotor, stator and consists of frame, main pole, commutating pole, end cover, bearing and electric brush device, etc. The rotor is by the shaft, the armature iron core, the armature winding, commutator and fan, etc. Below small make up said the stator frame in the play what role. I. Potest adhiberi polus et commutating polus et finem operimentum est fixum, et motor controller habent effectus firmamentum et solidamentum. II. Ob se pertinet ad partem magneticae circuitus, ita ut aditus inter magneticam polum, ita cursus basis satis mechanica vires et permeability resistentia. Est stare super ludere a partes, ut spero potest auxilium vobis.
