Scope

Main Technical Content: 4.1 The motor shall comply with the requirements of this standard and be manufactured in accordance with the drawings and technical documents approved through the prescribed procedures. 4.2 Under the following altitude and ambient air temperature conditions, the motor shall be able to operate at rated conditions. For deviations in on-site operating conditions, corrections shall be made in accordance with the provisions of GB/T 755-2019. — Altitude not exceeding 1000m. — The maximum ambient air temperature varies with the seasons, but does not exceed 40℃. — The minimum ambient air temperature is -15℃. 4.3 During motor operation, the deviations of power supply voltage and frequency from the rated values shall comply with the provisions of GB/T 755-2019. 4.4 When the motor operates at rated power, voltage, and frequency, its efficiency (according to GB/T 18613-2020) and guaranteed value of power factor shall meet the requirements of Table 15. — The motor's efficiency is determined by the method of loss analysis of input-output power (according to the provisions of GB/T 1032-2012, section 11.3). — In the calculation, the efficiency value takes four significant digits, and the power factor value takes three significant digits. — When measuring efficiency, the shaft sealing ring should be removed. 4.9 The tolerance of the guaranteed values of the motor's electrical performance shall comply with Table 20. The rounding interval for the values in items 4.5–4.8 is set to 0.01. Table 20 Tolerance of Electrical Performance Guarantee Values 4.10 The temperature rise of the motor's stator winding shall be performed in accordance with the following requirements: 4.11 Under the conditions of thermal state and gradually increasing torque, the motor shall be able to withstand a short-term overtorque test of the maximum torque value specified in item 4.7 (including tolerance) for 15 s, without sudden changes in speed, stalling, or ha
