三相电机启动时“嗡嗡”作响可能是由以下原因引起的：

　　电源电压低：如果电源电压低于电机额定电压，电机会无法正常启动或者启动困难，产生“嗡嗡”声。

　　电机损坏：电机内部损坏或轴承磨损等问题可能会导致电机无法正常启动或者启动困难，同时也会产生嗡嗡声。

　　电容故障：三相电机启动时需要使用启动电容，如果启动电容故障，电机无法正常启动，同时也会产生嗡嗡声。

　　过载或堵转：如果电机在运行时遇到了过载或者堵转情况，电机就无法正常运行，同时也会产生嗡嗡声。

　　电机绕组故障：电机绕组可能会出现断路、短路等问题，导致电机无法正常启动或者启动困难，同时也会产生嗡嗡声。

　　如果电机启动时出现嗡嗡声，可以通过检查电源电压、检查电机是否损坏或者堵转、检查启动电容是否正常以及检查电机绕组是否故障等方法来找出故障原因，并及时进行修复。同时，为了延长电机的使用寿命，应该注意电机的正确使用和维护。
