Applies to a.c., d.c., and universal machines of rated output up to 750 W (or 750 V.A.) per 1000 r/min with rated voltages up to 240 V d.c., up to 480 volt single-phase a.c., and up to 650 V three-phase a.c., intended for applications for which a light construction is adequate. Dimensions are specified for four frame sizes and for four methods of mounting. A shaft extension is specified for each frame size; in two cases an alternative smaller diameter shaft extension is specified. Preferred outputs between 2.5 W and 3000 W are listed but not allocated to frame sizes.

This Part of this standard specifies the dimensions and performance of a.c., d.c., and universal type electrical machines intended for applications for which a lighter construction than that specified in AS 1360, Part 10 is adequate and having the following characteristics:(a) Foot, flange, face-flange or resilient mounting.(b) Sleeve or rolling bearings.(c) Any type of enclosure.(d) A rated voltage up to and including 240 V d.c., 480 V single-phase a.c., or 650 V three-phase a.c.(e) A continuous rated output (or equivalent continuous rated output for short-time rated machines) up to and including 0.75 kW (or kV.A) for each 1000 r/min of the rated speed (or synchronous speed for a.c. machines).NOTE: It is recognized that in practice there is some overlap between the ratings covered by this Part and those covered by Part 10: e.g. motors of certain ratings may be constructed to comply either with this Part or with Part 10 but not necessarily with both.
