Inclusions The requirements in this standard apply to polyphase induction motors intended for use in power generating stations, including the following: a) Frame size larger than NEMA 440 series b) Squirrel-cage type c) Single speed or multispeed d) Horizontal or vertical...
This Practice covers minimum requirements for design, fabrication, inspection, testing, shipment, and documentation of squirrel-cage induction motors (above NEMA 440 frame sizes) for special purpose applications. This Practice is based upon API 541, Third Edition, and specifies...
This Practice describes the requirements for design, construction, and testing for NEMA premium-efficiency, horizontal or vertical, polyphase squirrel cage induction motors that are 4000 volts and below, including hazardous (classified) areas.
This Standard defines the electrical and mechanical requirements of induction-type light sources for use in roadway and area lighting luminaires.
This Practice covers minimum requirements for design, fabrication, inspection, testing, shipment, and documentation of squirrel-cage induction motors (above NEMA 440 frame sizes) for general purpose applications. This Practice is based upon API 541, Third Edition, and specifies...
GENERAL The intent of this specification is to outline the minimum requirements for three-phase ac induction motors applied to municipal and industrial applications for operation on voltages 5000 volts or less, rated 2500HP or less, operating more than 2000 hours per year at >75% of...
The standards in this guide cover alternating-current squirrel-cage motors up to and including the ratings built in frames corresponding to the continuous open-type ratings. PURPOSE This is a condensation of the standards on motors included in NEMA Motors and Generators,...
Preface to the Second Edition Throughout the years, many books and articles have been written about induction heat treating. In the author's opinion, Induction Heat Treatment of Steel, Lee Semiatin and Dave Stutz, 1986, was an excellent early source for induction heating and...
The second edition of the Handbook of Induction Heating reflects the number of substantial advances that have taken place over the last decade in theory, computer modeling, semi-conductor power supplies, and process technology of induction heating and induction heat treating....
This book aims at a theoretical and practical treatment of both conduction and induction heating. They shape a common theory, one being the 'mirror image' of the other, and so one get two for the price of one. The book comprises four parts: conduction theory, induction theory, heat...
This energy management guide provides practical information concerning the proper selection and application of medium AC polyphase squirrel-cage induction motors, including installation, operation, and maintenance in fixed frequency applications.
1.1 Scope. This specification provides the minimum fabrication, and quality requirements for the induction brazing of materials such as steels, copper, copper alloys, and heat- and corrosion-resistant alloys as well as other materials that can be adequately induction brazed. Note that...
This specification defines the requirements for locally hardening steel parts by the induction hardening method.
General This standard covers the requirements for form-wound induction motors for use in general purpose petroleum, chemical and other industrial severe duty applications and with the following characteristics: a) rated 185 kW [250 horsepower (hp)] through 2240 kW (3000 hp) for four-,...
This standard applies to premium-efficiency totally enclosed fan-cooled (TEFC), horizontal and vertical, single-speed, squirrel cage polyphase induction motors, up to and including 370 kW (500 hp), and 4000 V nominal, in National Electrical Manufacturers Association (NEMA)...
This recommended practice provides guidelines for the establishment of an induction hardening process for steel components. It is intended to be used as a guide for designers of induction hardened parts, for process auditors, and for purchase specifications and/or process sheets as...
