Let me give it a try... 1. 电机装在机器的哪个位置上？请拍一张照片。 Where in the machine does the motor get installed? Pls take a clear photo. 2. 拍一张清晰的安装孔的照片，机器已经更新换代了，老机器的接线可能跟新机器的接线不一样了。 Since the old machines have been replaced by new ones, which might have different connection systems, so be careful to take a picture of these mounting holes.
