Hawkins Electrical Guide v. 02 (of 10) / Questions, Answers, & Illustrations, A progressive course of study for engineers, electricians, students and those desiring to acquire a working knowledge of electricity and its applications

This practical technical guide presents a progressive question-and-answer treatment of armature design, winding practice, and motor components for electricians and students. It explains armature types and coil arrangements such as lap, wave, Siemens, and double windings, and details winding diagrams and procedures. The work examines armature theory, covering current distribution, armature reaction, eddy currents, lamination, and iron loss, and treats commutation issues including brush placement and sparking. It also addresses brushes and brush gear, mechanical armature construction, insulation and ventilation, and illustrated assembly and troubleshooting techniques for applied electrical machinery.
