<p>A dynamo-electric machine comprises a direct current machine with two wound rotors. One (1) of the rotors is fitted with an input shaft (12) and the other is fitted with an output shaft. The rotors are located near each other and in a common magnetic circuit provided by system of field windings (3) and magnets. The two rotor windings and the field windings are electrically connected to each other through electrical connection devices, of which one (4) is located on the input shaft (12) and the other is located on the output shaft. These electrical connection devices are associated with brushes (5) which may be movable or adjustable and which bear on the electrical connection devices. Associated with the machine is an electrical circuit which enables current generated by the action of one (1) of the rotors relative to the field to provide energisation for the other rotor, which acts as a motor in conjuction with the field.</p> |
