This standard specifies the energy efficiency grades, minimum allowable values of energy efficiency, evaluating values of energy conservation and test methods for line-start three-phase permanent magnet synchronous motor, permanent magnet synchronous motor for elevator, permanent magnet synchronous motor driven by variable frequency equipment (hereinafter referred to as permanent magnet synchronous motors).
This standard is applicable to the single-speed enclosed self-cooled line-start three-phase permanent magnet synchronous motor with voltage of 1140V or lower, power supply of 50Hz three-phase alternating current supply, rated power of 0.55~375kW and pole number of 2, 4, 6, 8, 10, 12 and 16 in continuous duty, the converter-fed permanent magnet synchronous motor for elevator with voltage of 1000V or lower and rated power of 0.55~110kW, and the converter-fed permanent magnet synchronous motor driven by variable frequency equipment with voltage of 1000V or lower and rated power of 0.55~90kW.
