The standards in this section apply to the following types of rotating machines: 1. Induction motors larger than fractional horse power (for definition of fractional horse power motor, see 9-60). 2. Induction generators. They are applicable also to induction...
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...
Preface Two motivations prompted the writing of this book: first, to acclaim the simple, technological elegance of the widely used polyphase induction motor and its frequently unrecognized importance to modern industry and the economic well-being of society; and second, to collect...
This standard covers instructions for conducting and reporting the more generally applicable and acceptable tests to determine the performance characteristics of single-phase induction motors, including non-excited synchronous motors. It is not intended that this standard shall...
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 construction...
This standard covers instructions for conducting and reporting the more generally applicable and acceptable tests of polyphase induction motors and generators. Many of the tests described may be applied to both motors and generators, as needed, and no attempt is made to...
This Standard covers integral horsepower, three-phase, alternating current, squirrel cage induction motors rated up to 15 kV at 50/60 Hz. This Standard also covers inverter duty motors. Note: This Standard may also be applied with discretion to products outside the scope of...
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 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 International Standard sets out guidelines for the online techniques recommended for the purposes of condition monitoring and diagnostics of machines, based on electrical signature analysis. This International Standard is applicable to three-phase induction motors.
The book covers various issues related to machinery condition monitoring, signal processing and conditioning, instrumentation and measurements, faults for induction motors failures, new trends in condition monitoring, and the fault identification process using motor currents...
This International Standard sets out guidelines for the on-line techniques recommended for the purposes of condition monitoring and diagnostics of machines, based on the electrical signature analysis. This part of ISO 20958 is applicable to three-phase induction motors fed from fixed...
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 induction motors shown below. This Standard covers the motors having the ratings of two or more voltages...
