Book Review: The Theory of Linear Induction Machinery

The Theory ofLinear Induction Machinery: M. POLOUJADOFF (Oxford University Press, 1980,276 pp. £15) In recent years there has been a substantial research activity in linear induction motors and this has led to a correspondingly high rate of publication of technical papers. Thus, in 1975 it was estimated that the publication rate approximately doubled between 1967 and 1970,and then increased by a further 50% between 1970 and 1972. Nevertheless, the topic remains a very specialised one, occupying a narrow band within the field of electrical machines. Furthermore, industrial applications of linear induction motors have not yet shown a growth commensurate with the research activity, although there has been much expenditure on investigations, particularly with reference to transportation schemes. At this point Professor PoloujadolT has contributed a very useful work which presents and compares various theoretical treatments of this class of machine. This will be very helpful to those requiring practical calculation methods and also to those commencing studies in this field. The book is also to be commended for its excellent final chapter which reviews the principal experimental projects conducted internationally. The bibliography of over 200 references will save many hours of searching by future workers. B. J. CHALMERS, Department ofElectrical Engineering and Electronics, UMIST
