1 Scope
This part of IEC 60034:
— specif ies test m ethods f or the determ ination of sound power level of rotating electrical m achines;
— specifies maximum A-weighted sound power levels for factory acceptance testing of network-supplied, rotating electrical machines in accordance with lEC 60034-1, having methods of cooling according to lEC 60034-6 and degrees of protection according to lEC 60034-5, and having the following characteristics:
• standard design, either a.c. or d.c., without additional special electrical, mechanical, or acoustical modifications intended to reduce the sound power level ;
• rated output from 1 kW (or kVA) up to and including 5 500 kW (or kVA);
• rated speed not greater than 3 750 min –1 .
— provides guidance for the determination of noise levels for a.c. cage induction motors supplied by converters.
