Conductor arrangement and transportable electrical drive device

A mobile electrical drive device having a conductor arrangement for transmitting electrical energy in a mobile system comprising a land vehicle, aircraft, or watercraft, the conductor arrangement comprising:

• an inner conductor;
• and
• an outer conductor arranged coaxially thereto,
• insulated from each other by an insulating layer,
• wherein the conductor arrangement is configured to electrically connect an electrical energy source to a drive motor for supplying the same with energy, wherein the conductor arrangement is designed for a DC voltage between the inner and outer conductors of less than 1000 volts,
• wherein the conductor arrangement connects a battery to the drive motor of the drive device, wherein the drive device comprises:
• a circuit configuration for feeding the drive motor implemented as a multiphase electric machine, the circuit configuration comprising a circuit board having one connection each for a positive pole and a negative pole for connecting to an intermediate circuit voltage;
• and
• at least one semiconductor power switch each mounted on the circuit board and connecting the positive pole and the negative pole to an output connection, forming a half-bridge circuit,
• wherein the connections for the positive pole and the negative pole and the output connection are each implemented having a flat area such that the connections for the positive pole and the negative pole are disposed adjacent to each other or one above the other relative to a plane of the circuit board and extend flat in axial and radial directions of the drive motor, and
• wherein the output connection is set up for providing a cycled voltage as an actuating signal for an electrical phase of the machine.
