This technical specification specifies test methods for determining losses and efficiencies of converter-fed AC inductionmotors within the scope of IEC 60034-1. The AC inductionmotor is then part of a variable frequency power drive system (PDS) as defined in...
This part of the IEC 60034 series applies to three-phase low-voltage cage inductionmotors of frame numbers 56 to 400 as specified in IEC 60072-1. This standard establishes procedures to obtain values for elements of single phase equivalent circuit diagrams from tests...
This International Standard is applicable to three-phase cage inductionmotors 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 2: for...
This International Standard specifies the performance requirements for fluorescent induction lamps for general lighting purposes. In this standard, the term "lamp" stands for "induction lamp". It may be expected that lamps which comply with this standard will start and operate...
This part of IEC 60034 specifies the parameters for eight designs of starting performance of single-speed three-phase 50 Hz or 60 Hz cage inductionmotors in accordance with IEC 60034-1 that: - have a rated voltage up to 1 000 V; - are intended for direct-on-line or...
This part of IEC 60034 specifies the parameters for four eight designs of starting performance of single-speed three-phase 50 Hz or 60 Hz cage inductionmotors in accordance with IEC 60034-1 that: - have a rated voltage up to 1 000 V; - are intended for direct-on-line or...
This International Standard specifies the safety requirements for fluorescent induction lamps for general lighting purposes. It also specifies the method a manufacturer should use to show compliance with the requirements of this standard on the basis of whole production appraisal in...
Scope and object This part of IEC 60110 is applicable both to indoor capacitor units and indoor capacitor banks intended to be used, particularly, for power factor correction in induction heating, melting, stirring or casting installations, and similar applications with controlled or...
This technical specification deals with the steady-state operation of cage inductionmotors within the scope of IEC 60034-12, when fed from converters. It covers the operation over the whole speed setting range, but does not deal with starting or transient phenomena. Only...
This part of IEC 60034 is intended to establish methods of determining efficiencies from tests, and also to specify methods of obtaining specific losses. This standard applies to d.c. machines and to a.c. synchronous and induction machines of all sizes within the scope of IEC...
This technical report deals with the steady-state operation of cage inductionmotors within the scope of IEC 60034-12, when fed from converters. It covers the operation over the whole speed setting range, but does not deal with starting or transient phenomena. Only indirect...
This part of IEC 60034 specifies efficiency classes for single-speed, three-phase, 50 Hz and 60 Hz, cage-inductionmotors 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...
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...
This Standard specifies the low-voltage top runner motors (hereafter referred to as motors) among the low-voltage three-phase 50 Hz and/or 60 Hz squirrel-cage inductionmotors shown below. This Standard covers the motors having the ratings of two or more voltages...
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 part of IEC 60034 specifies requirements relating to the use of thermal protectors and thermal detectors incorporated into the stator windings or placed in other suitable positions in induction machines in order to protect them against serious damage due to thermal overloads. It...
