Centrifuge Motor Repair & Rewinding Service in Guinea-Bissau
Engineering Excellence & Technical Support

• Customer Contact: The process begins when a client contacts the service provider, either by phone, email, or in person, to report a malfunctioning centrifuge motor or to request a rewinding service.

• Problem Description: The client provides details about the motor's issue (e.g., not spinning, making unusual noises, overheating, complete failure) and the type of centrifuge it's used in (e.g., laboratory, industrial).

• Urgency & Location: The client may indicate the urgency of the repair and provide the location for potential on-site assessment or pickup.

• Service Scope: The client clarifies whether they require a full repair, a specific component replacement, or a complete motor rewinding.

• Motor Collection/On-Site Inspection: Depending on the agreement, the motor is either collected from the client's premises or an on-site technician performs a preliminary inspection.

• Troubleshooting & Diagnosis: Skilled technicians diagnose the root cause of the motor's malfunction. This may involve visual inspection, electrical testing (e.g., resistance checks, insulation testing), and mechanical checks.

• Repair/Rewinding Scope Definition: Based on the diagnosis, the technician determines the necessary repairs (e.g., bearing replacement, brush replacement, capacitor issues) or confirms the need for a full rewinding.

• Parts & Material Estimation: The required spare parts and winding materials (copper wire, insulation, varnish) are identified and their costs estimated.

• Labor Estimation: The estimated labor hours for diagnosis, repair, and rewinding are calculated.

• Formal Quotation: A detailed quotation is provided to the client, outlining the scope of work, parts required, labor costs, estimated turnaround time, and any applicable warranties.

• Quotation Review & Acceptance: The client reviews the quotation and provides their approval to proceed.

• Work Order Creation: A formal work order is generated, documenting all details of the service request, including client information, motor specifications, agreed-upon scope, and cost.

• Disassembly: The centrifuge motor is carefully disassembled to access internal components.

• Cleaning & Inspection: All parts are thoroughly cleaned, and a detailed inspection is performed to identify any wear, damage, or corrosion.

• Component Repair/Replacement: Any identified faulty components (bearings, seals, brushes, etc.) are repaired or replaced with genuine or equivalent parts.

• Rewinding Process (if applicable):

- **Coil Removal:** The old windings are carefully removed.

- **Core Cleaning & Inspection:** The motor core is cleaned and inspected for damage.

- **New Coil Winding:** New copper coils are wound according to original specifications or optimized designs.

- **Insulation Application:** High-quality insulation materials are applied to protect the windings.

- **Coil Insertion & Securing:** The new coils are meticulously inserted and secured within the motor core.

- **Varnishing & Curing:** The windings are impregnated with insulating varnish and cured under controlled conditions to enhance durability and electrical properties.

• Reassembly: The motor is reassembled meticulously, ensuring all parts are correctly fitted and secured.

• Electrical Testing: Comprehensive electrical tests are performed, including insulation resistance, continuity, and surge testing.

• No-Load Testing: The motor is run under no-load conditions to check for smooth operation, correct speed, and absence of unusual noises or vibrations.

• Load Testing (if feasible/required): In some cases, the motor may be tested under simulated load conditions to verify performance under operational stress.

• Performance Verification: Key performance parameters are measured and compared against specifications.

• Final Inspection: A thorough visual inspection is conducted to ensure the motor is clean, correctly assembled, and free from any external damage.

• Test Reports: All test results and inspection findings are documented in a comprehensive report.

• Invoicing: The final invoice is prepared based on the agreed-upon quotation and any approved additional work.

• Warranty Information: Details of the warranty provided for the repair/rewinding service are clearly communicated.

• Client Notification: The client is informed that their centrifuge motor is ready for pickup or delivery.

• Motor Return/Installation: The repaired/rewound motor is either collected by the client or delivered and, if agreed upon, installed back into the centrifuge.

• Client Handover & Briefing: The client receives the motor along with the test report and warranty information. A brief explanation of the work performed may be provided.

• Post-Service Follow-up: The service provider may follow up with the client after a period to ensure the motor is functioning correctly and to address any concerns.
