Rotating Machines

Motor rewinding is a process that can help in the repair of shorted, grounded or damaged coils in a motor.

A motor rewind means that a coil is rewound and reinstalled for the necessary armatures or other components. The goal is to get the motor back to functioning at its optimal level.

Motor rewinding can help with motors that are either performing inefficiently or have stopped working altogether.

Electric motor reconditioning allows for planned inspection and refurbishment, allowing a deep-dive into the equipment to return it to a more efficient and reliable state. And this practice applies not just to motors, but to other electromechanical equipment as well.

The objective of this kind of maintenance is to prevent operating problems and make sure that the motor continuously provides a reliable operation Usually, preventive maintenance is a scheduled part of maintaining a whole system.

Balancing is the process of attempting to improve the mass distribution of a rotor, so that it rotates in its bearings without uncompensated centrifugal forces. This is usually done by adding compensating masses to the rotor at prescribed locations. It can also be done by removing fixed quantities of material, for example by drilling.

Bearing failure is a possible reason for overhauling your MV motor. Over time, bearings may expand too much due to overheating, eventually slipping out of place and misaligning with the shaft. Bearing seals may also no longer be in close contact and apply sufficient pressure on the bearing’s inner ring. This way, contaminants may slip into the bearing and stop it from functioning properly.

Diesel generator sets – used for either prime or backup (emergency) power – must be regularly maintained to ensure they provide quality power throughout their service life. Small investments made in replacing components and maintaining generators on a regular basis can save expensive and unnecessary upgrades or even replacement of the entire genset in the future.
