(Nobody got hurt, they just wet their pants)

As it fell i heard clicking. Not knowing too much about the keyang it scares me. It seems to work OK. I cannot turn the gear with my hand with no power and with power it spins. when the motor is moving a load i hear the same clicking when it stalls.

Any Idea whether it is broken?

Is the clicking coming from the motor or the breaker panels?
