Electric Motor Repairs And Preventive Maintenance Information

By Carol Anderson


Electric motors are devices which converts to mechanical energy from electrical energy and generators have their process opposite with this. This is used by diverse applications such as machine tools, power tools, blowers and pumps, disk drives, industrial fans and household appliances. They could be either powered by alternating or direct current.

Many companies under various industries are using them and is important for their daily operation so proper maintenance is required. But sometimes they fail and break down so you need experts in electric motor repairs Toronto to help you out. The following are a few things you should do during a preventive maintenance of these machines at your facilities.

Inspect them visually and take down notes of any details you may have noticed with its physical condition. You can discover many things such as corrosion or dirt buildup on their individual components specially when they are operated on rugged environments. These might indicate internal problems because debris could limit its performance.

Be sure to examine motor windings then search for any odor that smells like a burned one caused by overheating. The relay and contacts must be free from the rust and dirt also which are harmful for the equipment life. Place the machine where it will not be exposed to toxic elements, moisture, dirt and harsh conditions.

Check closely the brush and commutators and not wait for when the equipment stops working or inconsistencies are experienced before doing so. Be aware of any wear and tear signs in brush and if there is, they can lead to problems in commutation with the motor. That is why changing the brush is needed for regaining its functional integrity.

Commutator should be checked though due to its natural condition normally being polished and smooth. There must not be any dents, grooves or scratches because rough spots can suggest a sparking of brush there. Inspect thoroughly the stator, mount, belts and rotor then replace the components which their purpose cannot be served anymore due to wear.

Test the windings when every machine components have been inspected which would give you ideas on the existing failures or anomalies. Doing this is obligatory if you discovered burned odor, marks and cracks. Disassemble the motor in preparing the test consisting of rewinding motors and test the wind insulation to show information regarding the level of resistance.

Check bearings for some noises or vibrations because they signify issues such as dirt buildup, tear and wear, and poor lubrication. When they are impossible to touch because of being too hot then this may signify insufficient grease amount or overheating. Specific task could be needed that depends on equipment location, bearing type and motor application. So the bearing type must be known for determining the repair type required for it.

Take note of every test that was done during every preventive maintenance and the gathered results for establishing trends. Record every repair and replacement made on each component to understand better what every piece of these machines. Doing this is helpful for future inspections because they have documents stating what has been done previously on the equipment.
