摘要
介绍了矿用永磁同步变频调速电动机的检验标准现状,结合永磁同步电动机的低转速大转矩、需要变频器起动和调速等特点,提出了电动机性能检验方案和检验项目,给出了与检验自起动永磁同步电动机不同的检验方法和测量方法。试验结果表明,检验项目和测量的结果均能准确、有效的反映永磁同步变频调速电动机的性能情况。
The current status of inspection standards for permanent magnet synchronous frequency control motors for mines is introduced. Combining the characteristics of permanent magnet synchronous motors with low speed and large torque, frequency converter starting and speed regulation, etc., the motor performance inspection program and inspection items are proposed. The inspection method and measurement method are different from those of the self-starting permanent magnet synchronous motor. The trial results show that the inspection items and measurement results can accurately and effectively reflect the performance of the permanent magnet synchronous frequency control motor.
