强烈不建议使用！ 无人机电机密封圈脱落或丢失后继续飞行会引发严重风险，必须立即更换后再运行。原因如下：
一、立即停飞的三大原因：
润滑脂泄漏：电机轴承将在数十分钟内因缺乏润滑而过热卡死，导致电机报废。
粉尘入侵：空气中的尘埃、水分会直接进入轴承滚道，形成研磨效应，加速磨损。
动力失衡：多旋翼无人机若单个电机密封失效，可能因该电机转速异常导致失控炸机。
二、应急检测方法：
观察电机轴根部是否有油脂渗出（泄漏迹象）。
手动旋转电机听是否有沙沙异响（粉尘已侵入）。
用棉签擦拭轴根部检查是否沾有油污（润滑脂正在流失）。
三、临时处理方案（仅限迫降）：
若飞行中突发脱落，应立即：
保持飞机平稳悬停。
缓慢降落至安全区域。
降落後彻底清洁电机轴并更换密封圈。
四、更换密封圈注意事项：
安装前在唇口涂抹少量锂基润滑脂。
使用专用工具或套筒垂直压入，避免唇口翻折。
更换后需进行地面测试：手动旋转应顺畅无卡顿。
切记：密封圈是电机生命的“保险丝”，缺失状态下每多飞一分钟，电机报废风险增加50%！
