Understand EXACTLY how a DC Motor works. We discuss the construction & working principle of a DC Motor. Using Fleming’s left-hand rule, we show you how to determine the direction the winding will spin. Learn more about the operation of DC motors: [ Ссылка ]
The DC motor is of vital importance for the industry today and is equally important for engineers to look into the working principle of DC motor in details that we have discussed in this article. To understand the operating principle of DC motor we need to first look into its single loop constructional feature.
The very basic construction of a DC motor contains a current-carrying armature, connected to the supply end through commutator segments and brushes. The armature is placed in between the north pole and south pole of a permanent or an electromagnet as shown in the diagram above.
As soon as we supply direct current in the armature, a mechanical force acts on it due to the electromagnetic effect of the magnet on armature conductors. Now to go into the details of the operating principle of DC motor it is important that we have a clear understanding of Fleming’s left-hand rule to determine the direction of the force acting on the armature conductors of DC motor.
