The components developed by Magnet-Motor GmbH for the energy supply of electromagnetic launchers are explained as well as their combination to a mobile energy supply system is presented: Multiple Electronic Permanentmagnet (MEP)-motor and -generator, Magnetic Dynamic Storage (MDS) and superconducting inductive storage. Another part of the paper gives a report on a new coil gun launcher concept developed by Magnet-Motor. This work is part of the German-French government joint program on electromagnetic and electrothermal launchers and is carried out under subcontract of Rheinmetall/TZN-Germany.
