Rewinding Small Motors describes the technique of rewinding various types of motors, such as split phase, capacitor-start, repulsion, repulsion-induction, repulsion-start, shaded pole, three-phase induction, universal, and d.c. The book describes in detail the rewinding process. The technician should start by determining the following: (1) coil connection; (2) number of turns per coil; (3) number of coils per pole; (4) the gauge of the wire; and (5) the space occupied by the winding. The book notes the importance of the varieties of wind and the various techniques adopted to obtain the optimum wind for any particular type of armature. Varnishing and finishing forms part of the whole operation; this adds insulation between turns, secures the whole winding against the action of centrifugal force, and also seals the part from moisture or dust. A motor-driven winding machine should have speed control, a lead-screw reverser, and a wire guide. The book points out that a coil cannot be wound anyhow as the coil voltage governs the technique of winding that is to be used. The book is suitable for fitters, engineers, apprentices, technicians, and students of mechanical or electrical engineering.

First published in 1920, this comprehensive manual on armature winding and motor repair offers a detailed collection of practical electrical methods to fix motor and generator problems. To be used by maintenance specialists and electrical engineers, Daniel H. Braymer’s compilation of material was obtained through practical engagement in repair shop work, power station work and the maintenance of motors in industrial plants. Full of firsthand experience, the volume will provide answers to those needing assistance in armature winding and many other electrical problems that can occur within the workshop. Chapters in this volume include: Direct Current Windings Alternating Current Windings Repair Shop Methods for Rewinding D-C Armatures Testing Direct-Current Armature Windings Insulating Coils and Slots for D-C and A-C Windings Practical Ways for Reconnecting Induction Motors Inspection and Repair of Motor Starters, Motors and Generators Machine Equipment and Tools Needed in a Repair Shop Republished by Read & Co. Books, Armature Winding and Motor Repair continues to be considered a valuable asset within the subject. It provides a handy guide for any practical repairman looking to enlarge their knowledge of solving electrical problems while also appealing to amateurs just starting in the field.

This book reports the state of the art of energy-efficient electrical motor driven system technologies, which can be used now and in the near future to achieve significant and cost-effective energy savings. It includes the recent developments in advanced electrical motor end-use devices (pumps, fans and compressors) by some of the largest manufacturers. Policies and programs to promote the large scale penetration of energy-efficient technologies and the market transformation are featured in the book, describing the experiences carried out in different parts of the world. This extensive coverage includes contributions from relevant institutions in the Europe, North America, Latin America, Africa, Asia, Australia and New Zealand.

A fully expanded new edition documenting the significant improvements that have been made to the tests and monitors of electrical insulation systems Electrical Insulation for Rotating Machines: Design, Evaluation, Aging, Testing, and Repair, Second Edition covers all aspects in the design, deterioration, testing, and repair of the electrical insulation used in motors and generators of all ratings greater than fractional horsepower size. It discusses both rotor and stator windings; gives a historical overview of machine insulation design; and describes the materials and manufacturing methods of the rotor and stator winding insulation systems in current use (while covering systems made over fifty years ago). It covers how to select the insulation systems for use in new machines, and explains over thirty different rotor and stator winding failure processes, including the methods to repair, or least slow down, each process. Finally, it reviews the theoretical basis, practical application, and interpretation of forty different tests and monitors that are used to assess winding insulation condition, thereby helping machine users avoid unnecessary machine failures and reduce maintenance costs. Electrical Insulation for Rotating Machines: Documents the large array of machine electrical failure mechanisms, repair methods, and test techniques that are currently available Educates owners of machines as well as repair shops on the different failure processes and shows them how to fix or otherwise ameliorate them Offers chapters on testing, monitoring, and maintenance strategies that assist in educating machine users and repair shops on the tests needed for specific situations and how to minimize motor and generator maintenance costs Captures the state of both the present and past “art” in rotating machine insulation system design and manufacture, which helps designers learn from the knowledge acquired by previous generations An ideal read for researchers, developers, and manufacturers of electrical insulating materials for machines, Electrical Insulation for Rotating Machines will also benefit designers of motors and generators who must select and apply electrical insulation in machines.
