Stepping IEC Motor Standards

This technical specification gives the requirements for rotating control motors and describes the appropriate tests. It also gives dimensions and marking information and the details to be provided by the manufacturer in associated data sheets and catalogues. This technical specification is...

The second edition of this highly successful text has been greatly expanded and updated, and is now available in two companion volumes. Stepping into Palliative Care 2 focuses on symptom management, emergencies, bereavement and spirituality. This practical guide with numerous examples,...

This part of IEC 61800 applies to adjustable speed a.c. drive systems that include power conversion, control equipment and a motor. Excluded are traction for railway applications and electrical vehicle drives. It applies to power drive systems (see figure 1) with converter voltages...

This International Standard is applicable to a.c. contactors and/or contactor-based motorstarters designed for indoor installation and operation at frequencies up to and including 60 Hz on systems having voltages above 1 000 V but not exceeding 12 000 V. It is applicable only to three-pole...

The following topics are dealt with: Stepping motors; drive circuits; accurate load positioning: static torque characteristics; multistep operation: torque-speed characteristics; high-speed operation; open-loop control; closed-loop control; microprocessor-based stepping...

This technical report provides step-by-step information to aid RESPONSIBLE ORGANIZATIONS in implementation of the RISK MANAGEMENT PROCESS required by IEC 80001-1. Specifically, it details the steps involved in executing subclause 4.4 of IEC 80001-1:2010 and provides...

This part of IEC 62343, which is a Technical Report, describes failure mode effect analysis (FMEA) for optical units of dynamic modules. FMEA is one of the effective and useful analysis methods to determine the reliability evaluation test items and conditions that are defined in future...

This part of IEC/IEEE 80005 describes the data interfaces of shore and ships as well as step by step procedures for low and high voltage shore connection systems communication for non-emergency functions, where required. This standard specifies the interface descriptions,...

This document applies to medium power transformers from 25 kVA up to 3 150 kVA with highest voltage for equipment up to 36 kV, or in low voltage (LV) networks with highest voltage for equipment of up to 1,1 kV equipped with voltage regulating devices. Voltage regulating distribution transformers...

This part of IEC 61300 evaluates the effect of loads which is possible to occur when fibre optic devices are exposed to critical situations such as being stepped on, being run over by vehicle tyres, when an evenly-distributed static load is applied to the top surface of a street...
