ABSTRACT:
A drive arrangement including a flywheel, an electric motor drivingly connected to the flywheel for rotating the same is provided with a motion transmitting train operatively interposed between the flywheel and an output member of the drive arrangement for transmitting motion from the flywheel to the output member only after a certain number of revolutions of the flywheel about its axis, thereby permitting the flywheel to be accelerated under no-load conditions before the energy stored therein is transmitted to the output member and to a load connected to the same. Because energy can be supplied by the drive arrangement at a much higher rate than would be available from the electric motor, the drive arrangement is well suited for door operating units of a motorcar and the like which need to be installed in the limited space within the door.
