Electric Motor Repairs And Preventive Maintenance Information

By Carol Anderson


Electric motors are the machines that converts electrical energy to mechanical energy with generators being an opposite of this procedure. Diverse applications use this such as disk drives, machine tools, industrial fans, power tools, household appliances, and blowers and pumps. They could be powered with direct current or alternating 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.

Prioritize motor windings examination then look for any odor which smells like something is burned caused by overheating. Contacts and relay must also be free from dirt and rust which are harmful on the equipment life. Put the machine where the exposure to moisture, dirt, harsh conditions and toxic elements are less or none.

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 must be checked though because the condition it naturally has is being so smooth and polished. Any scratches, dents or grooves should not be there because rough spots could suggest a brush sparking is there. Thoroughly inspect the rotor, stator, mount and belts then replace components that could not serve their purpose anymore because of 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 any noise or vibrations as these signify problems such as wear and tear, poor lubrication and dirt buildup. When they become very hot to be touched then this can be signs of overheating or insufficient grease amount. Specific task might be needed depending on bearing type, motor application and equipment location. So you should know the bearing type to determine the repair it requires.

Take down notes of each test that was performed during each preventive maintenance and collect the results to establish trends. Record all replacements and repairs made on every component for understanding the machines better. Doing this helps future inspections through your documents of previous tests done.
