A gearbox (gear reducer) can reduce output rotation speed and get a big torque having the motor equipped with it.
Its reduction ratio is 1:3~1:180,which can be used together with the intermediate gear reducer to reach gear reduction ratio 1:1800.
GPG gearbox is very low noise and not required for oil change.
