摘要： An electrical machine, such as an electric motor, dynamo or alternator has a casing (26) with cooling vents (64) enabling cooling fluid (F) to flow into and out of the casing when the rotor (10) of the electrical machine rotates. The rotor (10) may be formed from conductive elements (44) connected together at their outer regions by inter-connecting members (40) which have vanes (68, 70) arranged to direct cooling fluid over the outer regions. Each conductive element (44) is a metal strip (45) with legs (46, 48) bent in opposite directions (D.sub.1, D.sub.2) relative to the plane of the strip. Portions of the windings (28, 30) of the rotor (10) are spaced apart to allow fluid to flow between the windings to enhance the cooling effect. With a current carrying rotor, the magnetic field intensity across the rotor is varied by varying the axial separation of the rotor and the stator (74, 76).

摘要： There is disclosed a rotor for an electrical machine, the rotor having a current-carrying winding comprising a plurality of circumferentially distributed winding portions which lie in at least one plane perpendicular to the rotor axis, and extend from a radially inner region to a radially outer region. A commutator is provided by surfaces of the winding portions at the inner region, and the winding is formed from a plurality of conductive sections, each having ends which lie at said outer region, interconnections between the winding sections being made only by way of those ends. Thus, soldered connections made between the winding sections will be remote from the commutator, which is the main source of heat for overheating, and moreover will be at positions where air cooling due to rotor movement is greatest. Air gaps between the winding portions at the outer region aid this cooling affect even further.

摘要： An electromagnetic device has a stator and a rotor rotating between facing surfaces of the stator and bearing a plurality of magnets distributed at regular intervals along its periphery. The magnets are so arranged that they form a sequence of alternately opposite poles on the surfaces of the rotor directed towards the stator, and the stator comprises two sets of independently supported magnetic yokes located at both sides of the rotor in front of the magnets. The magnetic yokes have two axially oriented arms, the end surfaces of which, in static conditions of the rotor, at least partly face a pair of successive magnets on a same surface of the rotor.

摘要： A variable speed DC motor contained within a housing having bearing openings at each end, an armature disposed in the housing and pivoted in the bearing openings, the improvement being a first cylindrical field shell surrounding the armature and having a pair of oppositely disposed field pole segments mounted the shell and facing the armature. There is a second cylindrical field shell surrounding the armature and also having a pair of oppositely disposed field pole segments mounted facing the armature. The motor also has a gear means coupled to each of the shells for angularly displacing said first and second shells opposite to each other with respect to the neutral axis of the motor.
