Low-voltage three-phase squirrel-cage induction motors-Low-voltage top runner motor

active, Most Current
Organization: JSA
Publication Date: 20 March 2014
Status: active
Page Count: 61
ICS Code (Motors): 29.160.30
scope:

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 and/or frequencies.

- Rated voltage 600 V or under

- Rated output 0.75 kW or over up to and including 375 kW

- 2, 4 or 6 poles

- Duty type S1 (continuous running duty) or S3 (intermittent periodic duty) having 80 % or more cyclic duration factor

- Commercial power source driven type

- Motors suitable for conditions of installation site specified in clause 6

This Standard also covers the following motors.

- Motors having flange, foot or shaft of special dimensions

- Motors incorporated in geared motors and brake motors irrespective of the shapes of shafts and/or flanges

This Standard does not cover the following motors.

- Motors that are driven exclusively by inverter.

- Motors which are completely integrated into a machine (for example, pump, fan and compressor) therefore which cannot be tested separately from the machine

NOTE: The International Standards corresponding to this Standard and the symbol of degree of correspondence are as follows.

IEC 60034-1: 2010 Rotating electrical machines-Part 1: Rating and performance

IEC 60034-8: 2007 Rotating electrical machines-Part 8: Terminal markings and direction of rotation

IEC 60034-9: 2007 Rotating electrical machines-Part 9: Noise limits

IEC 60034-12: 2007 Rotating electrical machines-Part 12: Starting performance of single-speed three-phase cage induction motors

IEC 60072-1: 1991 Dimensions and output series for rotating electrical machines-Part 1: Frame numbers 56 to 400 and flange numbers 55 to 1 080 (Overall evaluation: MOD)

In addition, symbols which denote the degree of correspondence in the contents between the relevant International Standards and JIS are IDT (identical), MOD (modified), and NEQ (not equivalent) according to ISO/lEC Guide 21-1.
