Beschreibung
Zusammenfassung:	The present invention discloses a motor efficiency analysis method for motor inverter. The method can be performed via a real-time motor operation efficiency display device. Based on the measured primary current signal and the voltage provided by the driving device, the device can estimate related data, such as the real-time efficiency, rotational speed, torque and stator resistance, by means of several algorithms. Besides, the device is designed to be applied to most motors; therefore, users can manage the efficiency of all motors of the factory without the need to stop the machines or the manufacturing process. 本发明公开种用于马达变频器的马达效率分析方法，其为与马达变频器结合的马达即时运转效率显示装置，该装置通过初级侧电流信号测量与驱动装置提供既有的电压数值，即可通过多个演算方法来估测出此负载点下，马达的即时效率、转速、扭矩、定子电阻的相关数据，符合现场配置的设计可让用户不须停机或影响生产工艺即可进行整厂的马达效能管理。
