Abstract
A flywheel system for a machine includes a rotary body affixed to a rotary shaft of the machine for rotating with the shaft as a unit; an additional rotary body forming a flywheel mass and being mounted on the shaft for rotation relative thereto; an electromagnetic device for torque-transmittingly coupling the rotary bodies to one another in a contactless manner; and a control for actuating the electromagnetic device.

A flywheel system for a machine having a rotary shaft, comprising
- (a) a rotary body adapted to be affixed to the shaft for rotating therewith as a unit;
- (b) an additional rotary body forming a flywheel mass and being adapted to be mounted on the shaft for rotation relative thereto;
- one of the rotary bodies being a first rotary body and another of the rotary bodies being a second rotary body;
- (c) control means;
- and
- (d) electromagnetic means for torque-transmittingly coupling said first and second rotary bodies to one another in a contactless manner;
- said electromagnetic means including
- (1) a plurality of pole bodies mounted circumferentially on said first rotary body in a uniform distribution;
- each pole body having a pole face oriented towards a surface of said second rotary body;
- (2) a separate coil carried by each said pole body;
- and
- (3) means for electrically connecting each said coil with said control means for actuating said electromagnetic means.
A flywheel system for a machine having a rotary shaft, comprising
- (a) a rotary body adapted to be affixed to the shaft for rotating therewith as a unit;
- (b) an additional rotary body forming a flywheel mass and being adapted to be mounted on the shaft for rotation relative thereto;
- said rotary body adapted to be affixed to the shaft having a flywheel mass less than an effective flywheel mass of said additional rotary body;
