Salient Pole Rotor Coils
LH Marthinusen manufactures and refurbishes salient pole rotor coils for use in hydro, synchronous and power generation applications. These coils are designed to meet the electrical and mechanical requirements of large rotating machines, supporting reliable performance in demanding operating environments.
Manufacturing and Refurbishment Capabilities
Our capabilities include both the manufacture of new coils and the re insulation of existing coils. This allows equipment to be restored to operational condition while maintaining compatibility with original machine designs.
Coils are produced using:
- Sectional conductors wound directly onto the rotor
- Flat conductor configurations depending on application requirements
Manufacturing Equipment and Processes
The manufacturing process is supported by specialised equipment to ensure accurate and consistent coil production, including:
- Multi-stage hydraulic consolidation press
- Rectifier controlled insulation curing systems
- Bespoke tooling for precise coil manufacturing
- Deflection tester to verify mechanical integrity
These processes support consistent quality and reliable coil performance.
Conductor and Insulation Systems
A range of conductor insulation systems is available to suit specific operating conditions, including:
- Enamel insulation
- Double glass insulation
- Enamel and glass combinations
- Nomex insulation systems such as B stage Prinom or Thermopreg materials
Through controlled manufacturing processes and material selection, LH Marthinusen delivers salient pole rotor coil solutions that support reliable operation in hydro and power generation applications.
