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

Due to the continued success of projects in the field of kinetic energy storage drives, e+a is an ideal partner for applications that require operation of a motor in a vacuum.
