  1. Electric Motor Repair vs. Replace – Costs, Benefits

    Leave a Comment

    Almost any industrial activity depends on an electric motor. When repair vs. replace considerations arise, the choice can result in thousands of dollars saved or lost. This is partly due to the direct repair/replacement costs but also as a result of downtime that grinds operations to a halt. Making the right call between electric motor replacement vs. repair is thus extremely vital to minimizing downtime and costs.

    Should You Repair or Replace Your Electric Motor?

    It’s essential to make time for regular servicing appointments. Preventative maintenance is the most reliable way to keep long-term equipment costs low, as poorly serviced electric motors are a common cause of motor repair and replacement issues. Consider these factors when deciding whether to replace or repair your electric motor:

    Electric Motor Repair vs. Replace

    Electric Motor Repair vs. Replace
    • Environmental impact: Repairing motors results in less waste by extending the lifespan of existing equipment while reducing demand for new motor manufacturing. It can also help operations meet financial and waste-reduction goals.
    • Lead time: Compare the lead time for repair and replacement. Generally, repairs have a shorter lead time than new motors, which tend to take longer to order, ship, and install in your facility.
    • Extent of damage or wear: If the severity of a motor’s damage is extensive, repairs may be more costly than replacement. Worn brushes, bearings, or capacitors can be cost-efficiently repaired, while major damage to windings or other essential parts could be beyond repair.
    • Cost of repair vs. replacement: Generally, if electric motor repair costs reach 50% to 75% of the cost of replacement, it may be a better idea to replace the motor.
    • Motor age: At some point, motors reach the end of their expected lifespan, where repairs occur more frequently and the one-time cost of replacement is justified. If the motor is relatively new and the cost of repair is reasonable, repair is the better choice.
    • Parts availability: Waiting on parts for outdated motors or uncommon brands can create costly downtime. Replacement parts can even become difficult or impossible to find and result in extensive custom repair work.
    • Energy efficiency: New electric motors are often more energy efficient, resulting in greater long-term energy and cost savings.
    • Performance requirements: Determine whether the motor, once repaired, would meet the output and efficiency requirements of your operation. If not, you may need to replace it.
    • Downtime and lost productivity: Assess the financial impact of motor downtime in your production. Perhaps the downtime is expensive, and it’s more financially feasible to do a quick replacement rather than an extensive repair.
    • Service history: On reviewing a motor’s maintenance history, look for signs of recurring issues. This could make a replacement electric motor the smarter option.
    • Technological upgrades: Replacing your motor with a newer model may be worth the higher cost if you need the enhanced features.
    • Warranty coverage: See if your electric motor is still under warranty because this alone can significantly cut your repair costs.
    • Expert opinion: Motor technicians and engineers can provide a reliable assessment of the motor’s true condition and then suggest the most effective solution.

    A cost-benefit analysis using the points above will help determine whether industrial electric motor repair or replacement is the wisest course of action. Compare each choice’s short- and long-term benefits and decide what your cost threshold is where repair is no longer cost-effective.

  2. Motor Bearing Failure 101 – Types & Causes

    Leave a Comment

    Bearings are a critical element of electric motors. They facilitate even load handling, reduce friction, provide shaft support, and enhance the reliability and longevity of rotating components. However, without proper installation, operation, and maintenance, bearings can become damaged or fail. Here, we’ll go over some of the most common causes of bearing failure and how to prevent them.

    Common Causes for Motor Bearing Failure

    Common Causes for Motor Bearing Failure

    Some of the most common causes of motor bearing failure include:

    Motor Bearing Failure 101

    Motor Bearing Failure 101
    • Improper lubrication & fretting. Improper lubrication can lead to overheating and excessive wear on bearings. The lack of lubrication can also cause fretting, which develops when two dry and dissimilar surfaces move against each other, resulting in corrosion.
    • Corrosion & contamination. Contaminants such as water, sand, dirt, and chemicals can lead to various problems in bearing assemblies. For instance, they can erode/corrode bearing surfaces or degrade the lubricant, all of which can cause premature failure.
    • Misalignment. Misalignment between the shaft and bearing housing can be caused by contaminated components, bent shafts, or improperly positioned locking nuts and shafts. These problems can result in excessive vibrations and uneven load distribution, which can lead to failure.
    • Fatigue. Bearings are subjected to repeated cycles of load and stress during operation. Over time, this can lead to material fatigue and the development of cracks in bearing components, ultimately causing the bearing to fail.
    • Moisture. Outdoor or humid environments can lead to moisture seeping into your bearings. This creates the ideal setting for rust and corrosion development that contributes to bearing failure.
    • High temperatures. It’s important to refer to your motor’s operating guide for lubrication requirements and working temperature. Incorrect lubricant can bleed in even mild temperatures, resulting in a variety of lubricant-related problems. High temperatures can also decrease bearing hardness, leading to cracks.
    • Incorrect installation. Bearing failure can be caused by improper installation and setup. The most common installation mistakes include imbalance, incorrect mounting, and misalignment or excessive shaft run-out.
    • Electrical damage. The passage of electrical currents through the bearing can lead to electrical erosion, or arcing. This can cause various issues, including lubricant degradation, pitting damage to the rolling elements and raceways, and premature bearing failure.
