more teeth on the pinion , more speed , less torque
less teeth on the pinion , more torque, less speed

more teeth on the spur , more torque, less speed
less teeth on the spur , more speed , less torque


more turns in motor ,more torque, less rpm, lower amp draw
less turns in motor ,more rpm , less torque, higher amp draw

also taller gearing (speed)= more amp draw
shorter gearing (torque) = (USUALLY) less draw
