適用范圍：This part of IEC 60034 specifies efficiency classes for single-speed, three-phase, 50 Hz and60 Hz, cage-induction motors that:? have a rated voltage UN up to 1 000 V;NOTE The standard also applies to motors rated for two or more voltages and/or frequencies.? have a rated output PN between 0,75 kW and 375 kW;? have either 2, 4 or 6 poles;? are rated on the basis of either duty type S1 (continuous duty) or S3 (intermittent periodicduty) with a rated cyclic duration factor of 80 % or higher;? are capable of operating direct on-line;? are rated for operating conditions in accordance with IEC 60034-1, Clause 6.Motors with flanges, feet and/or shafts with mechanical dimensions different fromIEC 60072-1 are covered by this standard.Geared motors and brake motors are covered by this standard although special shafts andflanges may be used in such motors.Excluded are:? Motors made solely for converter operation in accordance with IEC 60034-25.? Motors completely integrated into a machine (for example pump, fan and compressor) thatcannot be tested separately from the machine.
