*DC drives still untill now the most powerful speed control for heavy industries due to its torque, high stability, excellent for heavy driven mechanical loads.

*DC drives feed back may be tachogenerator,incremental encoder, or absolute encoder to get stability of motor speed.

*DC drive is suitable for linear forward direction rotation with used in many heavy industries as iron and steal industry, Plastic industry.

*DC drive control done by field control or armature control, 99% of control application be armature control. as speed be function of armature voltage directly proportionality. Percentage of repair DC drive in Technotronics company.

*DC drive up to 5KW can be repaired as

 90% for power failure.

80%  for control failure.

depand on nature of damage area of DC drive. 

*DC drive more than 5KW can be repaired as:

80% for power failure.

70% for control failure

In 90% of repaired DC drive the repair cost be from 30% to 50% of new DC drive price with guarantee one year according to our guarantee conditions explained in our web site.
