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...
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.
PURPOSE AND USE OF PROCESS INDUSTRY PRACTICES In an effort to minimize the cost of process industry facilities, this Practice has been prepared from the technical requirements in the existing standards of major industrial users, contractors, or standards organizations. By harmonizing these...
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 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.

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.
Induction motors are the most important workhorses in industry. They are mostly used as constant-speed drives when fed from a voltage source of fixed frequency. Advent of advanced power electronic converters and powerful digital signal processors, however, has made possible the...
