This International Standard is applicable to three-phase cage induction motors and establishes two methods for determination of efficiency: • Method 1: for motors tested by using a torque measurement device, with additional load losses derived from measurements; • Method...
This technical specification specifies test methods for determining losses and efficiencies of converter-fed AC induction motors within the scope of IEC 60034-1. The AC induction motor is then part of a variable frequency power drive system (PDS) as defined in IEC...
This Standard specifies the test methods and marking requirements, and references energy efficiency levels for three-phase induction motors. Note: The test methods contained in this Standard are not limited to specific types of motors, but where this Standard is...
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 Practice describes the requirements for design, construction, and testing for motors in accordance with IEC requirements for single-speed, horizontal or vertical, polyphase squirrel cage induction motors that are 1000 volts and below. This Practice covers motors...
This part of IEC 60034 specifies efficiency classes for single-speed, three-phase, 50 Hz and 60 Hz, cage-induction motors that: • have a rated voltage UN up to 1 000 V; NOTE - The standard also applies to motors rated for two or more voltages and/or frequencies. • have a...
This part of IEC 60034 specifies efficiency classes for single-speed, three-phase, 50 Hz and 60 Hz, cage-induction motors that: • have a rated voltage UN up to 1 000 V; NOTE The standard also applies to motors rated for two or more voltages and/or frequencies. • have a...
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 document establishes a classification for fan efficiency. It applies to all electric-motor-driven fan systems that utilize a specific combination of components as defined below: a) fan airflow performance determined in accordance with an accepted performance standard; b)...
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...
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.
This International Standard specifies test methods for determining losses and efficiencies of converter-fed AC motors (AC induction motors) within the scope of IEC 60034-1, operating with variable speed.
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...
