- Scope
- This part of IEC 60034 specifies efficiency classes for single-speed, three-phase, 50 Hz and 60 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 $1 (continuous duty) or $3 (intermittent periodic duty) 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 from IEC 60072-1 are covered by this standard. Geared motors and brake motors are covered by this standard although special shafts and flanges 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) that cannot be tested separately from the machine.
