Direct Current Motors high profitability is mostly depend on fixed commanded units and the possibility of changing speed in changable tybe of duties.
Sensitivity rotation conrols helps to maximise the quality of production,increase the profit and cause more control over production line.

In Direct Current Motors, by changing voltage we can change rotation and by changing armature current we can control the torgue. In DC shunted motors the moment has been fixed.The Rotation can be gained regulation unstept and homogeneous in the period of changing weight. By the help of the feedback of tako generator we can gain high sensivity in rotation.

Direct Current Motors serve posibilities for using synchronize controlling systems.With DC motors mostly it's possible to control rotation and torque values from outsidde, beside of this many systems can be work in serial or parallel and also it' s posible to make fix attraction windings.
