Design and Testing of Electrical Machines
A Dahlander motor also known as a pole changing motor , dual- or two speed-motor is a type of multispeed induction motor , in which the speed of the motor is varied by altering the number of poles; this is achieved by altering the wiring connections inside the motor. The motor may have fixed or variable torque depending on the stator winding. It is named after its inventor Robert Dahlander — Robert Dahlander, a Swedish engineer working for ASEA ,  discovered that switching the poles in a motor led to a reduction in the speed of the motor. The new connection was named the "Dahlander connection" and a motor having such a configuration is commonly referred to as a "pole changing motor" or a "Dahlander motor".

Deshpande Book Summary: This textbook offers a practical approach to electrical machines, featuring clear-cut explanations of fundamental principles, and attention to industrial practices in design and testing of electrical machines. The basic theory, principle of operation and characteristics of transformers, three-phase induction motors, single-phase induction motors, synchronous machines and dc machines are dealt with in Appendices to provide the background for the design of these machines. The initial chapters of the book are devoted to basic parameters of design of electrical apparatus, characteristics of magnetic, electric and insulating materials, construction of electrical machines, and basic design requirements of magnetic and electrical circuits of machines. Detailed procedures for designing transformers, three-phase induction motors, single-phase induction motors, synchronous machines and dc machines are explained in a simple and logical way.
Возбужденный, Беккер ускорил шаги в поисках телефона. По другой стороне улицы, оставаясь невидимым, шел человек в очках в тонкой металлической оправе. ГЛАВА 27 Тени в зале шифровалки начали удлиняться и терять четкость. Автоматическое освещение постепенно становилось ярче. Сьюзан по-прежнему молча сидела за компьютером, ожидая вестей от Следопыта. Поиск занял больше времени, чем она рассчитывала. Мысли ее мешались: она тосковала по Дэвиду и страстно желала, чтобы Грег Хейл отправился домой.
