What is Induction Motor Maintenance ?

Induction motor maintenance definition

Induction motor maintenance involves operations that increase the life of the equipment and help it operate more efficiently.

Maintenance types of induction motors

Squirrel cage induction motors: Squirrel cage induction motors require much less maintenance because they do not contain brushes, commutators, or slip rings.

Coil rotor induction motor: Because it contains slip rings, brushes, so it does need to be maintained from time to time.

Maintenance type

Maintenance is divided into restorative (corrective)

This type of maintenance occurs after a failure occurs. It has the disadvantages of shortening the service life of the machine and wasting energy. It is also known as corrective maintenance.

Protective (preventive) type

This relates to planned measures taken to prevent breakdowns and failures. Examples include oil changes, lubrication, belt tightening, and filter changes.

Common fault

Stator winding fault
Bearing failure
Rotor fault

Maintenance schedule

Regular maintenance tasks should be performed weekly, every five/six months, and once a year to keep the motor in good condition.

Importance of maintenance

A proper maintenance schedule is essential to prevent costly repairs and ensure efficient operation, especially for three-phase induction motors.

Vibration Testing and Fault Research of High - Voltage Shunt Reactors

1 Vibration Monitoring and Fault Diagnosis Technology for High - Voltage Shunt Reactors1.1 Measuring Point Layout StrategyVibration characteristic parameters (frequency, power, energy) of high - voltage shunt reactors are fully recorded in operation logs. For vibration analysis, focus on resolving the complexity of electric field distribution at winding ends. Quantitatively evaluate field - strength distribution under operating/lightning overvoltage and voltage gradient characteristics of longit

Research on Online Diagnosis of Secondary Circuit Faults of Electronic Current Transformers

1 Principle and Role of Electronic Current Transformers1.1 Working Principle of ECTAn Electronic Current Transformer (ECT) is a key device for managing safe power system operations, converting large currents into manageable small-current signals for measurement and control. Unlike traditional transformers (relying on direct magnetic field interaction between primary and secondary windings), ECTs use sensors (e.g., Hall effect sensors) to detect magnetic field changes from the primary winding. Th

What are the fault diagnosis and handling technologies for 35kV combined transformers?

What are the fault diagnosis and handling technologies for 35kV combined transformers?

For fault diagnosis and handling of 35kV combined transformers, the following technical means can be adopted:Insulation Fault DiagnosisUse equipment such as high-voltage test transformers, power frequency withstand voltage testers, and partial discharge detection systems to conduct a comprehensive assessment of the insulation performance of combined transformers. When the insulation resistance is found to be lower than 1000MΩ or the dielectric loss factor tanδ exceeds 0.5%, an applic

What are the common faults of low-voltage voltage transformers?

Open - Circuit Fault on the Secondary SideOpen - circuit in the secondary side is a typical fault of low - voltage voltage transformers, showing abnormal voltmeter readings (zero/fluctuation), faulty power meters, buzzing noises, and core overheating. When open - circuited, the secondary voltage spikes (no secondary current to balance the primary EMF), causing core saturation, flux distortion, and potential overheating/damage.Causes include loose terminals, poor contact, or human error.
