F030 fault in DC drive 6RA70:dc master

During running condition one of DC motor tripped showing “F030” fault...........It some times tripped in running condition especially in 3X12mm rolling showing F030 fault. We used DC drives from Siemens and the model was 6RA70. Read more

Speed Regulation in DC Drives

From this equation we can say that with constant field flux and load on the motor, any change in incoming supply voltage will change the voltage delivered to the armature of the motor. Read more

Direction Reversal of D. C. Motor

As we know the torque developed M≈ IaΦ. Thus to develop torque in reverse direction either Armature current should be reversed. Or Φ should be reversed. To reverse Φ means Field Current should be reversed.Read more
