Electric motors operate many essential systems onboard a vessel, including seawater pumps, ballast pumps, fans, compressors, ventilation equipment and hydraulic machinery. Continuous operation, humidity, heat, vibration and heavy starting loads can eventually affect motor windings and mechanical components. Our Motor Repair & Rewinding in Lome service provides inspection, overhaul, rewinding and testing for marine electric motors.

A motor that trips its protection device, overheats, produces excessive noise or fails to start may have several possible causes. The fault can originate from the winding, insulation, bearings, rotor, starter or power supply. Proper diagnosis is therefore required before deciding whether the motor needs a simple repair or complete rewinding.

MARINE ELECTRIC MOTOR INSPECTION

Motor troubleshooting begins with electrical and mechanical checks. Voltage, current, winding resistance and insulation resistance can be measured to identify abnormal electrical conditions.

The motor housing, terminal box, cooling arrangement and cable connections are also inspected. Signs of overheating, moisture penetration, burned insulation or loose terminals can indicate the cause of repeated motor failures.

Mechanical condition is assessed through examination of the shaft, bearings, coupling and rotor movement. Excessive vibration may indicate bearing wear, rotor imbalance, misalignment or other mechanical problems.

MOTOR REWINDING SERVICES

When winding damage is extensive, rewinding may be required to restore the motor. The damaged winding is carefully removed and the stator core is inspected before new winding work begins.

The replacement winding is prepared according to the motor's original electrical characteristics, including voltage, frequency, number of poles and winding configuration. Proper insulation materials and winding techniques are important for achieving reliable operating performance.

After winding installation, the stator is treated and prepared for electrical testing. Insulation resistance and other appropriate tests are performed before the motor is returned to service.

BEARING AND ROTOR REPAIR

Bearings are critical to motor reliability. Worn or damaged bearings can create excessive vibration, heat and shaft movement, eventually affecting the winding and rotor.

Bearing replacement can be carried out during motor overhaul. The rotor and shaft are also checked for scoring, corrosion, imbalance and mechanical damage.

Where required, rotor balancing and shaft-related corrective work can be considered to improve smooth operation and reduce vibration.

MOTOR TESTING AND COMMISSIONING

Following repair or rewinding, the motor should be tested before being placed back into normal service. Insulation condition, winding resistance and electrical connections can be checked, while operational tests can monitor current, vibration, temperature and rotation.

The motor's performance under its intended application can also be assessed when suitable testing conditions are available.

Our Motor Repair & Rewinding in Lome service supports motors used throughout marine machinery and auxiliary systems. For a ship at Lome Port, motor repair can often be coordinated with planned maintenance or equipment downtime.

Whether the ship has a burned winding, insulation failure, bearing damage, overheating or a motor that will not start, technical inspection can determine whether the unit requires repair, rewinding or component replacement.
