This standard specifies 50H. Or the four design parameters of the starting performance of the 60H2 single-speed three-phase cage induction motor. The motor should comply with GB 755-2000 standard, and. The rated voltage does not exceed 1 000 V; . Direct starting or star-delta starting; . There is no juice according to the S1 working system type; ． Can have any level of protection. This standard also applies to dual-voltage motors with the same degree of magnetic saturation under both voltages, as well as increased safety motors in the T1 to T3 temperature groups that comply with GB 3836.1-2000 and GB 3836.3-2000 standards. Note 1: This standard does not require each manufacturer to produce motors of all four designs. The selection of any design according to this standard will be negotiated by the manufacturer/·and the user. Note 2: Special-purpose motors do not need to comply with the above four design regulations. Note 3: The torque values and apparent power values given in this standard are limit values (minimum or maximum values, no tolerance). However, it should be noted that the values given by the manufacturer on the sample may include tolerances, and the tolerances should comply with the provisions of the GB 755-2000 standard. Note 4: The stalled rotor apparent power listed in the attached table corresponds to the symmetrical steady-state current effective value when the rotor is stalled. When the motor is connected to the current, there will be an o. The 5-week asymmetric instantaneous peak current is 1.8-2.8 times the steady-state value. The peak value and decay time of this current are a function of the motor design and closing phase angle.
