Summary

TLDRIn this video, the presenter provides an overview of electrical motor maintenance and repair. The focus is on two main types of maintenance: preventive and turnaround. Preventive maintenance involves tasks like inspecting the motor visually, cleaning components, checking for loose or corroded parts, and ensuring proper insulation resistance. Turnaround maintenance includes more in-depth actions such as rewinding, bearing replacement, and balancing the stator. The presenter emphasizes the importance of regular maintenance to keep motors running at peak performance. The video concludes with an encouraging message to stay motivated in learning and maintenance practices.

Takeaways

  • 😀 Perform regular visual inspections of the motor to detect any issues early.
  • 😀 Clean the motor body and cooling fins to ensure proper airflow and prevent overheating.
  • 😀 Inspect and clean the motor's cooling fan to maintain efficient cooling.
  • 😀 Check the motor cover for loose or corroded bolts that could affect motor performance.
  • 😀 Replace or repair the cooling fan and motor cover if damaged.
  • 😀 Inspect the terminal box for voltage and ensure it is sealed properly.
  • 😀 Use a megohmmeter to measure the insulation resistance of the stator or rotor, with a minimum of 0.5 MΩ.
  • 😀 Test the insulation resistance of motor cables using a megohmmeter or hipot device.
  • 😀 Regularly check transformers and current systems to ensure proper functionality.
  • 😀 Replace or lubricate bearings to ensure smooth motor operation and prevent wear.

Q & A

  • What is the main focus of the motor maintenance lesson?

    -The main focus is on electric motor maintenance and repair, specifically ensuring the motor operates optimally through preventive and turnaround maintenance.

  • What does preventive maintenance involve for electric motors?

    -Preventive maintenance involves a series of tasks aimed at ensuring the motor is in good condition, such as visual inspections, cleaning, and checking components like the fan, bolts, and insulation.

  • How do you perform a visual inspection of an electric motor?

    -The motor should be examined visually to check for any visible abnormalities such as damage or wear on parts like the body, fins, and cooling system.

  • Why is cleaning the motor's body and fins important?

    -Cleaning the motor's body and fins removes dust and debris that could affect the motor's efficiency and cooling, preventing overheating and damage.

  • What is the purpose of inspecting the motor’s cooling fan?

    -Inspecting and cleaning the cooling fan ensures that it is working properly, preventing overheating and maintaining efficient motor performance.

  • What should be checked regarding the motor's cover during maintenance?

    -The motor’s cover should be checked for any loose or corroded bolts, as well as any damage that could compromise the motor's protective casing.

  • What should you do if the cooling fan or cover is damaged?

    -If the cooling fan or cover is damaged, they should be repaired or replaced to ensure the motor’s cooling system works effectively and the motor remains protected.

  • How is insulation resistance measured in a motor, and what value is considered acceptable?

    -Insulation resistance is measured using a megger, with an acceptable resistance value being at least 0.5 Mega Ohms for the stator or rotor.

  • What is the importance of checking the motor’s wiring insulation?

    -Checking the motor’s wiring insulation ensures there are no faults that could lead to short circuits or electrical hazards. This is done using a megger or hipot tester.

  • What does turnaround maintenance involve for electric motors?

    -Turnaround maintenance involves more intensive repairs, including tasks like rewinding, replacing bearings, balancing the stator, and servicing motor accessories such as switches.
