適用范圍：This International standard specifies the parameters for four designs of starting performanceof single-speed three-phase 50 Hz or 60 Hz cage induction motors in accordance withIEC 60034-1 that:? have a rated voltage up to 1 000 V;? are intended for direct-on-line or star-delta starting;? are rated on the basis of duty type S1;? are constructed to any degree of protection.The standard also applies to dual voltage motors provided that the flux saturation level is thesame for both voltages and to motors having type of protection 'e – increased safety' withtemperature classes T1 to T3 complying with IEC 60079-0 and IEC 60079-7.NOTE 1 It is not expected that all manufacturers will produce machines for all four designs. The selection of anyspecific design in accordance with this standard will be a matter of agreement between the manufacturer and thepurchaser.NOTE 2 Designs other than the four specified may be necessary for particular applications.NOTE 3 The values of torque and apparent power given in this standard are limiting values (that is, minimum ormaximum without tolerance), but it should be noted that values given in manufacturers' catalogues may includetolerances in accordance with IEC 60034-1.NOTE 4 The values tabled for locked rotor apparent power are based on r.m.s. symmetrical steady state lockedrotor currents; at motor switch on there will be a one-half cycle asymmetrical instantaneous peak current whichmay range from 1,8 to 2,8 times the steady state value. The current peak and decay time are a function of themotor design and switching angle.
