Electric motor repair service is often necessary when a motor malfunctions. The windings of the rotor and stator are often the most common problem areas. Worn out bearings are also known to cause problems, especially with efficiency. After determining that your electric motor is faulty, it is important that you hire the best engineers and technicians to repair it.

Motor Rewinding

When single phasing of power supply occurs at the workplace, or protective circuits fail to protect the motor windings from power surges, the windings might burn out. Buying a replacement motor might be an option, but for larger motors, rewinding the stator and rotor is often a good idea.  A three phase motor can be rewound as many times as possible provided the casing, shaft, and end bells are in good shape.

Rewinding should only be done by experts using specialized equipment to ensure that the new set of windings have the same number of turns and patterns. The conductor used should also have the same diameter as the one that was there before. This will ensure that the motor has the same power output.

Machining Services

Motor repair is not all about rewinding, there is also machining. There are many types of machines which can be used in smoothing surfaces, enlarging existing holes and drilling new ones. When rebuilding a dead motor, the casing, shafts, fans and end bells also may need to be worked on. Bearings need to be replaced.

Maintenance Services

The main reason why machines often fail is due to lack of servicing.  Machines do not need to break in order to be serviced. This should be done on a regular basis. For instance, all motors should be serviced at least twice a year during annual maintenance and in between scheduled maintenance. This may involve replacement of bearings and greasing of parts. The coupling units like gearboxes connected to the motor should also be well lubricated. Any machine should be well lubricated to reduce friction and enhance efficiency. Depending on how many hours the motor runs, moving parts should be greased regularly.

It is not enough to rebuild a damaged motor or install a new one. The reason behind the breakdown must first be determined. If your technicians are not able to pin point the main cause of the problem, talk to the experts from Priest Electric for a more accurate diagnosis, and to prevent similar failures.
