Current and Voltage Unbalance causes and counter measures

Any unbalance above 3% hampers the motor efficiency. 3. Torque (and thus the speed) produced by the motor becomes fluctuating. These sudden changes in torque cause more vibration in the gear box or the equipment connected to it. The vibration and noise produced damages the equipment and also reduces the efficiency of equipment. 4.

Unbalance: The Common Cause of Vibration IRD Balancing

Unbalance The Common Cause of Vibration & Premature Bearing Destruction within Rotating Machinery Equipment. Unbalance is defined as an unequal distribution of mass causing the mass axis to differ from the bearing axis. During rotation, the unequal mass along with the radial acceleration due to rotation create a centrifugal force.
