Motors for energy storage
Since 2008, e+a Elektromaschinen und Antriebe AG has been supplying rotors & stators for kinetic energy storage systems using flywheel technology.
Design Challenges:
- Electrical insulation performance in a vacuum
- Thermal issues in vacuum environments
Expertise:
- Motor operation in a vacuum, typically with flywheel energy storage devices
- Testing of slot insulation materials in a vacuum
- Evaluation of optimized stator windings during vacuum operation
- Calculation of power losses, especially in the rotor
