Millimeters- roll out value for metric units The amount of revolutions that the this gearing combination will cause the driving wheels to turn in one minute. This is the RPM value entering the transmission through spur gear, not taking transmission ratio into account. The amount of revolutions that the motor and pinion and spur gear combination will cause the transmission to turn in one minute. You need atleast two inputs in this calculator. Resistor, Capacitor, Time - Input / Output. This can be used to calculate Resistor or Capacitor for a given time in seconds. The motor spins this many rounds per minute. This calculator will help you to calculate the time constant when using Resistor and Capacitor in series. A nominal voltage for LiPo batteries is 3.7 v per cell. The kilovolts amount indicates how many revolutions the motor will make in one minute per volts appliedīattery voltage when fully charged. The amount of revolutions that the pinion gear must turn in order to turn the wheels one revolution.Įnter the kilovolts amount of the motor. The middle/idle gear doesn't have to be taken into account in calculations.

It is presumed that the transmission consists of 3 gears. You can set the transmission ratio to 1:1 value, calculate the ratio based on transmission gear sizes or manually enter the ratio if it is already known. Transmission ratio unknown, calculate as 1 : 1 The number reflects how many revolutions does the pinion gear make to turn the spur gear one revolution. Use at your own risk :-) The calculated values are not saved anywhere. RC car gearing calculator RC car gearing calculator Entities
