About Gear motor (combined with motor and reducer gearbox)
Original motor speed ÷ Deceleration ratio = output speed
For example:
Gear ratio = 1:298; Motor no-load speed = 6V 10000; Output speed = 10000 ÷ 298 = about 6V 30RPM
Common torque unit: 1N.M = 10KG.CM = 0.1KG.M
About the torque of the motor:
"Strength", if the motor torque is too small, can't drive to take the weight of the object.
Calculation formula:
Output speed (no-load speed) after motor reduction
= Motor no-load input speed/gearbox reduction ratio
Motor rated output speed
= Rated motor input speed / gearbox reduction ratio Motor no-load input speed / gearbox reduction ratio * 80%
Output torque of motor after deceleration (rated torque)
= Motor load torque * reduction ratio * gearbox efficiency
