 Selecting the reduction gear ratio
Two selection criteria may be applied.
 The first criterion concerns the required speed output of the reduction gear only. It is adequate for most applications and is easy to apply.
Given that :

N1 = required speed of geared motor
Nb = basic nominal speed of motor

 The second criterion concerns the required usable power output of the motor. The rotational speed of the motor is given by :
N = speed of motor (rpm)
No = no-load speed of motor (rpm)
P = required output power (W)
Cd = start-up torque of motor (Nm)
This gives the equation :
In order to avoid using numbers less than 1 where the reduction ratio is concerned, the value 1/R is employed.
Due to the fact that it is always a reduction gear and not a «multiplier» gear, there should be no ambiguity concerning the number used.
