Cons of Stopping shaft connected to gearbox

Hi,



I'm new to this field. I'm interested in knowing electrical motor/generator operations. I have few questions here could you please help me. Qtn: I have a shaft rotating a minute and not rotating 10 seconds. i.e 1min rotates + 10sec stopped + 1min rotates + 10...and so on. In this case does gear box provides constant output? or does gear box needs continuous rotating shaft? what are the cons if the shaft stops like this?



Thanks a million in advance!
