Foreword
This standard is a revision of JB/T58001991 "Technical Conditions for YH Series (IP23) Marine Three-Phase Asynchronous Motors (Frame Size 160~315)".
Compared with JB/T5800-1991, the main changes of this standard are as follows: The writing format is in accordance with GB/T1.1-2000 and GB/T1.2-2002. This standard adds technical indicators for motors with fans and motors with rated voltage of 440V and rated frequency of 60Hz. According to the actual manufacturing and use conditions, the guaranteed value of the ratio of the motor's stall torque to the rated torque and the noise value of the A-weighted sound power level measured at no-load are modified. According to the provisions of GB/T4772.1-1999, the motor installation dimension A/2 is deleted. According to the provisions of GB10068-2000, the vibration limit of the motor is modified. According to the provisions of GB755-2000, the tolerance of the guaranteed value of some parameters of the motor is supplemented. According to the provisions of China Classification Society's "Steel Seagoing Ship Classification and Construction Rules" (2001), the ambient temperature, inclination and temperature rise limit of the motor are modified.
This standard adjusts the order of some clauses of the original standard. This standard replaces JB/T58001991.
