How to calculate the motor with gearbox output specs?

1. Output Speed(No-load)=Motor Speed(No-load)/Reduction Ratio

2. Output Torque=Motor Torque*Reduction Ratio*Gearbox Efficiency

e.g.:

PM-33126000-30K
1. Output Speed(No-load)= 6000/ 30=200RPM

2. Output Torque= 45* 30* 73%=985.5gf.cm≈1kgf.cm=0.098N.m
