摘要:
The paper derives the equations required in the prediction of the steady-state characteristics of an alternator supplying a synchronous motor, which is of particular interest in electric ship propulsion. These equations are valid for any degree of saliency and any value of synchronous reactance in either machine. Since considerable labour is required in the numerical evaluation of the equations, the power, terminal voltage, armature current and pole angles at pull-out; as functions of the machine synchronous reactances, are given in the form of tables or families of curves. A curve is given showing the variation of the pull-out power with saliency, and another shows the extent to which the pull-out power of a combination of two machines is reduced in comparison with the values which would be obtained if either machine were running on an infinite busbar.

摘要:
The paper describes two further and improved 3:1 pole-changing windings which both have only nine control leads, and in which a 60° spread has been used, instead of the 120° spread which was used in a machine previously described. A particular feature of these windings is that the coil pitch is critical, and can have only one value. Full-pitched coils cause very bad crawling effects.

摘要:
The paper is an extension of the author's earlier paper which gave details of the incidence, together with an explanation, of the large amount of sheath fracture experienced with lead and lead-alloy sheathed cables run on hooks. The conclusion was reached that, with correct design, satisfactory life can be obtained for cables so installed.As a result of that work the author has been led to the further conclusion, briefly recorded in the discussion on the earlier paper, that, contrary to the common view, installation on spaced supports is preferable to any other method where this alternative is available.The reasons for this conclusion are discussed, and the consideration of construction on spaced supports is extended both as to method and analysis of behaviour. A new method, employing pairs of supports instead of single ones, is described.The principles and conclusions are applicable to lead- or aluminium-sheathed cables of solid, oil-filled, or gas-pressure type, and to communication cables.
