Armature Coils
LH Marthinusen manufactures and refurbishes armature coils used in a variety of industrial rotating electrical machines. These coils are produced to meet the electrical and mechanical requirements of DC machines operating in demanding industrial and transport environments.
Armature coils are manufactured to suit specific machine configurations and operating conditions, supporting reliable electrical performance and long service life.
Applications
Our armature coils are used across several machine types, including:
- Industrial DC motors
- Traction motors used in electric and diesel locomotives
- Motor generators
- Motor alternators
Each coil is designed and produced to match the required machine configuration.
Conductor and Insulation Systems
A range of conductor and main wall insulation systems are available to meet application requirements. These include:
- Kapton insulation
- Enamel insulation
- Double glass insulation
- Enamel and glass combinations
- Nomex insulation systems
- Conductor bonded mica or Mylar insulation
- Poroband insulation materials
These insulation systems support both mechanical strength and thermal performance within the coil structure.
Manufacturing and Testing
LH Marthinusen applies controlled manufacturing processes and material selection to maintain consistent coil quality. Comprehensive coil testing forms part of the production process to verify insulation integrity and electrical performance before installation.
Through specialised manufacturing equipment and experienced technical teams, LH Marthinusen delivers armature coil solutions that support reliable operation of DC machines across industrial, traction and power generation applications.
