Understanding That Electric Motor Repair Can Be Complicated

Some people do not even realize that a number of the machines and equipment they use every day operate using an electric motor until something goes wrong with it. Fortunately, there are some engine problems that you can fix yourself but, on occasion, you will come across problems that only an expert should attend to, otherwise you could find yourself in need of a new motor instead of a simple electric motor repair. So, why are some repairs more complicated than others?

When we use electronic machines or equipment, we expect them to work properly and to get the job done. When the motors in these machines or equipment fails, we tend to feel shocked and almost betrayed at the fact that they are not working as they are supposed to be. In these sorts of situations, when emotions are running high, it is often best to get an expert in who knows what they are doing. The main reason for this is that they will be familiar with all components of the equipment.

There is one way, however, to tell whether you are able to fix the problem yourself or whether you will need to take the machine or equipment to a professional. The first thing you should do when you suspect your motor has stopped working is to turn it off and unplug it. This gives the equipment or machine some time to reset. Once some time has passed, trying plugging it back in and see whether it's now working.

Occasionally, you will find that after doing this test your equipment or machine is working perfectly once again. Often, this simply means that it was feeling slightly overworked or hot and needed some time to cool down. If your motor is still not working properly or is now refusing to start, you know that you are in need of some professional electric motor repairs.

Fortunately, many of the machines that run off electric motors will be fitted with an early warning system that gives you plenty of time to book in a repair before the problem gets out of hand. In an electric car, for example, a service light will come on when the motor is beginning to experience a problem that could eventually become problematic. This allows the driver plenty of time to book in a repair at a convenient time.

The next time your machinery or equipment decides to stop working, consider what sort of motor it operates on - you could be in desperate need of an electric motor repair. Take it to a professional that specializes in your type of machine or equipment, explain your problem and leave it in their very capable hands.

That's the mechanism for a Free Energy AC generator - no fuel needed - Self-powered generator.

The Basic Steps of Electric Motor Repair

During electric motor repair, it is vital to document all nameplate information. Never allow someone to take off your nameplate! It’s a crucial part of your motor. We also clean parts and visually inspect the electric motor.

Measuring & Testing during Electric Motor Repair:

When we complete an electric motor refurbishment, we measure the motor’s components such as shaft runout, bearing journals, bearing housings, keyways, output shaft diameter, and more. Furthermore, we also conduct testing of the rotor conditions through a growl test and hot spot tests. At this stage during an electric motor repair, we test the windings through surge testing, phase resistance, insulation resistance megger, Hi-pot (AC destructive, DC non-destructive), and visually insect the electric motor winding.

Machining:

Depending on the condition of the motor, machining is a necessary part of the electric motor repair process. Our in-house machining department works on failed housing, repairing or manufacturing new shafts, and more. For electric motor shaft repair, we can weld and machine shafts, chrome and grind, make a new shaft, and straighten a shaft. We also ensure the proper material is selected and also heat treat material as necessary. Pro Tip: Watch out for some unacceptable practices such as punching/peening of housings, gluing in bearings, JB welding, glue or stubbing).

Dynamic Balancing for Electric Motor Repair:

KINETIC POWER SYSTEM’s electric motor repair shop follows and exceeds ISO 1940-1 standards for repair on all rotating apparatus. Balancing is an important step in the electric motor repair process, as it greatly impacts the longevity of the motor repair.

Electric Motor Stripping: 

The stripping of your windings is a very important part of the electric motor refurbishment process. Ask your shop how they strip your windings. KINETIC POWER SYSTEM utilizes MotorSafe stripping that protect the motor and its laminations.

Electric Motor Rewinding:

Electric motor rewinding is very detail oriented and can impact the longevity of your electric motor. We rewind motors back to OEM specifications or greater, using the proper wire selection and high quality materials such as phase paper, insulation, and slot liners. Pro tip: Ask your shop if they use automated coil winding machines. KINETIC POWER SYSTEM uses automated machines for the best windings possible. 

Electric Motor Varnishing: 

After rewinding, an electric motor is varnished to electrically insulate the winding and to mechanically protect it from contamination & vibration. We use the following methods: Dip & Bake, Vacuum Pressure Impregnation, Trickle Varnishing, and Ultra Seal. 

Assembly & Testing: 

After winding and varnishing, the electric motor is re-assembled and tested during our quality control process.

Painting: 

The final step of the electric motor repair process is painting. We paint every motor that has been repaired and follow any request from our customers. Furthermore, we ensure that the nameplate is secured and any necessary labeling is on the motor.
