PREFACE 



p ms book has been compiled as a foundation for lecture courses 

 junior and senior students in Electrical Engineering, 

 ""he theory and characteristics of electrical machines are devel- 

 ed from the fundamental principles of electrostatics and electro- 

 magnetics. Only the more standard types have been discussed 

 since familiarity with the principles of their operations will guide 

 the student to a cc iplete understanding of other machines which 

 differ only in mine f respects. This general groundwork may be 

 extended to suit the requirements of particular classes.
