Rewinding Stator
Kamol Engineering Service Co., Ltd. specializes in the design, manufacturing, repair, and maintenance of motors and generators for both alternating current (AC) and direct current (DC), covering voltages from 380 volts up to 25,000 volts.
Our coils are produced from flat copper conductors using a hot-press process, enabling coil lengths up to 8.6 meters and supporting unlimited horsepower, with production time of only 10 seconds per coil. Every piece is manufactured to international standards for maximum precision, durability, and quality.
When the stator is damaged… don’t let production come to a halt.
Warning Signs and Common Issues
The stator is the heart of a motor or generator, and damage can seriously impact your operations. Signs that a stator may require maintenance include:
- Abnormally high motor temperature
- Loss of power or noticeably reduced efficiency
- Frequent breaker tripping
- Unusual noise or vibration
- Burn marks or a burning smell from the windings
Our stator rewinding service is a cost-effective solution to restore your machinery to like-new condition.
Our Standard Stator Rewinding Process
Transparent and Traceable Service Procedures
| 1. Inspection and Problem Analysis | 2. Careful Removal of Old Windings | 3. Slot and Insulation Preparation | 4. Rewinding with Premium Materials | ||
| We receive the motor and record preliminary data, followed by advanced electrical testing using instruments such as EL CID and Tan Delta to accurately identify the root cause of the failure. | The damaged windings are professionally removed from the stator core, ensuring no harm to the core structure or surrounding components. | Each slot is thoroughly cleaned and fitted with new, high-quality insulation materials to prepare for the installation of new windings. | New windings are made using high-grade copper and standardized winding techniques to achieve optimal electrical performance and reliability in line with engineering specifications. | ||
| 5. VPI (Vacuum Pressure Impregnation) Varnish Process | 6. Assembly and Finishing | 7. Final Testing and Quality Assurance | |||
| The stator undergoes VPI varnish impregnation, allowing the varnish to deeply penetrate under vacuum and pressure, thereby enhancing mechanical strength and insulation integrity. | All components are precisely reassembled, with replacement of consumable parts such as bearings and seals as required to ensure smooth operation. | Comprehensive post-repair electrical tests are conducted, including Insulation Resistance, Surge Test, and Hi-Pot Test, to verify that the motor is ready to perform at full efficiency. | |||
